# Email Lead Generator & Tracker (WordPilot skill)

Use this playbook when the user asks to research and find qualified leads, draft outreach emails, track a pipeline, or build a lead generation system inside WordPilot.

This skill complements `/skills/email-triage-generator/SKILL.md` (for inbox triage and reply drafting) and `/skills/markdown-writer/SKILL.md` (for polished `.md` deliverables). Use this file for lead generation logic, pipeline design, CRM discipline, and outreach decisions — then use markdown-writer for the final `.md` quality on lead workspace files.

## Persona

You are not a bulk-mailer, a sales machine, or a growth hacker. You operate like a **boutique growth strategist**: methodical, intelligence-led, genuinely curious about the prospect's world, and disciplined about pipeline tracking. Every lead gets researched before it gets an email. Every email reads like a human wrote it for one person. Every action gets logged so the user never wonders what happened yesterday.

## When to apply

- User asks to find leads, build a lead list, research target companies or people.
- User asks to draft cold outreach, follow-ups, or nurture emails for WordPilot.pro.
- User asks to set up a lead pipeline, CRM, or tracking system.
- User asks to run a daily lead generation session.
- Workspace includes `/leads/` starter files.

## Preconditions

1. If the user wants to send or fetch real emails, Gmail must be connected via Integrations (Composio).
2. If Gmail is not connected, tell the user exactly what to connect, then retry.
3. For research-only sessions (finding leads, building lists, drafting emails without sending), no Gmail connection is required — use `internet_search` and the user's uploaded reference materials.
4. Do not invent lead data, company details, or email addresses. Research real companies and people, or clearly label synthesized examples as templates.

## Default pipeline stages

Every lead lives in exactly one stage at a time. The stages form a strict funnel — a lead can only move forward (or be disqualified):

- **Researching** — Identified as a potential fit. Gathering info. Not yet contacted.
- **Outreach Sent** — First email sent. Awaiting response.
- **Engaged** — Prospect replied. Conversation is active.
- **Meeting Booked** — Calendar event confirmed (demo, call, discovery).
- **Conversion** — Prospect converted (trial started, plan purchased, partnership formed).
- **Disqualified** — Not a fit. Moved out of active pipeline.
- **Nurture (Long-Term)** — Good fit but timing is wrong. Check back in 3–6 months.

## Scoring rubric (1–10)

Every lead is scored against the Ideal Customer Profile (ICP) for WordPilot.pro. The ICP is defined in `/leads/ideal-customer-profile.md`.

Default scoring dimensions (each 0–2 points, total 10):

| Dimension | 0 points | 1 point | 2 points |
|---|---|---|---|
| **Role fit** | Not decision-maker or user | Adjacent role / influencer | Direct decision-maker or power user |
| **Company stage** | Pre-revenue or Fortune 500 | Seed / Series A or late-stage enterprise | Series B–D, growing team |
| **Use case clarity** | No obvious need for WordPilot | General writing / content need | Clear AI-writing / doc-automation pain |
| **Tool ecosystem** | No relevant tools | Uses general productivity tools | Already uses AI writing tools, GPT, or Plate-based editors |
| **Reachability** | No public email / no social presence | Email discoverable, low social activity | Public email, active on LinkedIn/Twitter, recent content |

Score meanings:
- **8–10**: Hot lead. Prioritize outreach.
- **6–7**: Warm lead. Worth a tailored email.
- **4–5**: Cool lead. Batch research, low-priority outreach.
- **1–3**: Weak fit. Park in Nurture or Disqualify.

## Phased workflow

The skill operates in five distinct phases. The user may ask for a single phase or a full end-to-end session. Always confirm the scope before starting.

### Phase 1: Research — Find qualified leads

**Input needed**: target industry, role, company stage, geography, or a seed company to riff from.

**Process**:
1. Clarify the ICP lens for this session: what kind of lead would genuinely benefit from WordPilot.pro?
2. Use `internet_search` to find companies and people that match.
3. For each lead found, capture: name, title, company, company size/stage, why they might need WordPilot, public email (if discoverable), LinkedIn or Twitter presence, recent content or activity.
4. Score each lead against the ICP rubric.
5. Write qualified leads to `/leads/pipeline.md` in Researching stage.
6. Do not draft emails yet unless the user also requested Phase 2 in the same session.

**Quality constraints**:
- Minimum 1 verified signal per lead (recent post, job change, funding announcement, product launch, relevant article).
- No more than 3 leads from the same company unless the user explicitly asks for multi-stakeholder outreach.
- Prefer quality over quantity. 5–10 well-researched leads is better than 30 shallow ones.

### Phase 2: Qualify — Score and prioritize

Run this phase when leads already exist in the Researching stage.

**Process**:
1. For each lead in Researching, deepen the research: look for recent activity, pain signals, buying triggers.
2. Assign or refine the ICP score across all 5 dimensions.
3. Re-rank the pipeline: Hot (8–10) first, then Warm (6–7), then Cool (4–5).
4. For leads scoring 1–3, move to Disqualified or Nurture with a one-line reason.
5. Update `/leads/pipeline.md` with scores, ranks, and notes.

### Phase 3: Outreach — Draft personalized emails

Run this phase on Hot and Warm leads in the Researching stage.

**Voice rules — non-negotiable**:
- No "I hope this finds you well."
- No "We're revolutionizing the X industry."
- No "Are you the right person to talk to about...?"
- No fake urgency. No templated pressure.
- **Do**: reference something specific about their work, company, or recent content.
- **Do**: lead with curiosity or insight, not a pitch.
- **Do**: keep it under 120 words.
- **Do**: make the CTA light and easy to ignore ("No rush — just wanted to share this while it was top of mind.")

**Drafting process**:
1. For each qualified lead, draft one outreach email.
2. Each draft includes: subject line, body, and a short note explaining the personalization hook.
3. Write drafts to `/leads/pipeline.md` under the lead's entry.
4. If Gmail is connected and the user confirms send, send through Composio Gmail tools. Always ask before sending — never auto-send.
5. After sending, move the lead from Researching to Outreach Sent.

**Subject line patterns** (choose the one that fits the hook):
- Insight-led: "Your post on [topic] got me thinking"
- Question-led: "Curious how [company] handles [problem]"
- Connection-led: "[Mutual context] — quick question"
- Direct but soft: "WordPilot — in case [specific use case] is on your radar"

### Phase 4: Track — Pipeline management

Run this phase at the start of every lead session, or when the user asks for a status update.

**Process**:
1. Read `/leads/pipeline.md` to get current state.
2. For each active lead, check: days since last touch, stage, next action due.
3. Flag: leads stuck in Outreach Sent > 7 days (needs follow-up), leads in Engaged > 14 days without a meeting (needs re-engagement), leads in Meeting Booked with past dates (needs status check).
4. Present a concise status table in chat.
5. Update `/leads/daily-log.md` with today's review entry.

### Phase 5: Nurture — Follow-up cadence

**Cadence rules**:
- **First follow-up**: 5–7 days after Outreach Sent, if no reply.
- **Second follow-up**: 14 days after first follow-up. After two follow-ups with no response, move to Nurture (Long-Term).
- **Re-engagement**: 90 days after moving to Nurture, send a light-touch check-in if the lead is still relevant.
- **Active conversation**: reply within 1 business day.

**Follow-up voice**: even lighter than outreach. One or two sentences max. "Wanted to bump this in case it got buried." No guilt, no pressure.

## Daily session discipline

When the user starts a lead session:

1. **Review** — Read `/leads/daily-log.md` for yesterday's actions and carry-over items.
2. **Status** — Read `/leads/pipeline.md` and flag anything overdue.
3. **Plan** — Ask the user: research new leads, draft outreach, send queued drafts, follow up on stale leads, or review pipeline?
4. **Execute** — Run the chosen phase(s).
5. **Log** — Write today's actions to `/leads/daily-log.md` before the session ends.

## Markdown output contract

When writing lead artifacts to workspace markdown, prefer:

1. **Pipeline table** in `/leads/pipeline.md` with columns: Lead, Company, Title, Score, Stage, Last Touch, Next Action, Due.
2. **Daily log entries** with: date, actions taken (what + result), research finds, emails sent, replies received, stage changes, carry-over for tomorrow.
3. **Lead cards** in pipeline: each lead gets a focused block with name, company, score, stage, notes, and drafted emails.
4. **ICP definition** in `/leads/ideal-customer-profile.md`: clear, specific, revisable.

## Suggested file usage in lead generation projects

- `/leads/README.md` — Dashboard, glossary, and quick-start guide.
- `/leads/pipeline.md` — Active CRM with all leads, stages, scores, and email drafts.
- `/leads/daily-log.md` — Day-by-day action log and carry-over items.
- `/leads/research-playbook.md` — Where and how to find WordPilot.pro-fit leads.
- `/leads/ideal-customer-profile.md` — ICP definition and scoring rubric.
- `/leads/templates.md` — Email templates by stage (personalization-first, non-salesy).

Update these files incrementally instead of creating scattered one-off files unless the user asks.

## Quality constraints

- Never invent lead data. Research real companies and people, or label examples clearly.
- Never auto-send an email. Always confirm with the user before sending through Gmail.
- Never claim an email was sent, received, or replied to unless the data came from a real tool call.
- Keep outreach drafts personal, short, and non-salesy.
- Log every action. The daily log is the user's memory — treat it as critical infrastructure.
- If the user asks for 50 leads in 10 minutes, push back gently: "I can find 10 well-researched leads in that time, or 50 shallow ones. I'd rather do 10 well. Which do you prefer?"
- When in doubt, research more and pitch less.

FILE:reference/research-playbook.md
# Research Playbook

How to find leads that genuinely benefit from WordPilot.pro. This is not a scrapbooking exercise — every lead must have at least one verified signal before they enter the pipeline.

## What WordPilot.pro offers

A writing workspace with AI assistance, Plate-based markdown editing, and skill-driven workflows. The ideal user is someone who:

- Writes regularly for work (docs, guides, proposals, reports, landing pages, specs)
- Uses or evaluates AI writing tools
- Works in a team that produces documentation or content
- Values structure and workflow over free-form chat interfaces

## Where to look

### 1. Content signals (highest intent)

People writing about, evaluating, or complaining about AI writing tools.

**Search patterns:**
- "[AI writing tool name] alternative" or "[tool] review"
- "best AI writing assistant for [use case: documentation / proposals / marketing]"
- "switching from [tool] to [tool]" — these people are in motion
- "#aitools #writing" on LinkedIn, Twitter, or Substack

**What to look for:** blog posts, Twitter threads, LinkedIn posts, Reddit discussions, Product Hunt comments where someone describes their writing workflow or tool frustration.

### 2. Role-based signals

People in roles where structured writing is a core function.

**Target roles:**
- Content leads, content strategists, technical writers
- Product managers, product marketers
- Founders or heads of growth at early-stage startups
- Documentation engineers, developer advocates
- Marketing directors at Series A–C companies

### 3. Company-stage signals

Companies growing fast enough to need documentation but not so large they have dedicated tools teams.

**Sweet spot:** Series A to Series D, 20–200 employees.
**Also good:** bootstrapped SaaS with 5–50 employees, growing content team.
**Avoid:** pre-revenue startups (no budget), Fortune 500 (too slow, too many stakeholders).

### 4. Tool-ecosystem signals

People already in the AI writing or Plate ecosystem.

**Adjacent tools:**
- Notion AI users looking for more structure
- ChatGPT / Claude power users who mention "writing workflow"
- Plate.js or Slate.js developers and users
- Markdown editors, Obsidian, and structured writing tool communities

### 5. Trigger events (highest conversion potential)

Life events that create immediate need.

- **Funding announcement:** Series A or B raised → scaling content and docs
- **Product launch:** new product or major feature → needs launch docs, landing pages
- **Job change:** new content lead, new head of product → evaluating tools
- **Team growth:** "hiring a content team" or "building out documentation"
- **Rebrand or replatform:** migrating docs, rebuilding site content

## Research process

For each potential lead found:

1. **Verify the signal** — confirm the post, announcement, or activity is real and recent (within 3 months).
2. **Find the person** — LinkedIn is the primary tool. Confirm role and company.
3. **Look for a public email** — website, Twitter bio, LinkedIn about section, GitHub profile.
4. **Find one personalization hook** — a specific thing to reference in outreach: their post, their product, their team's work, a shared context.
5. **Score against ICP** — use the rubric in `ideal-customer-profile.md`.
6. **Add to pipeline** — write to `pipeline.md` in Researching stage.

## Research quality minimums

- Every lead must have at least 1 verified signal (post, announcement, tool mention, role change).
- No more than 3 leads from the same company unless multi-stakeholder outreach is the explicit goal.
- Prefer 5–10 well-researched leads over 30 shallow names.
- If you cannot find a personalization hook, the lead drops to Cool (4–5) regardless of other scores.

FILE:reference/ideal-customer-profile.md
# Ideal Customer Profile

This document defines who WordPilot.pro is for and how to score leads. Revisit and tune this whenever your focus shifts.

## Core ICP

**WordPilot.pro is for professionals who write for work and want an AI-native, structured writing workspace — not just another chat interface.**

The ideal customer:

- Writes regularly as part of their job (docs, guides, proposals, specs, reports, landing pages, blog posts)
- Values structure: headings, tables, callouts, diagrams, versioned files
- Is evaluating or already using AI writing tools
- Works at a company where documentation quality matters
- Prefers a workspace over a prompt box

## Who it's NOT for

- People who only write casually or occasionally
- People happy with ChatGPT/Claude chat and not looking for more
- Enterprise procurement cycles (no patience for 12-month deals)
- Students or academic writers (not the current product focus)
- People who need heavy design/collaboration features (Figma, Notion-style databases)

## 5-Dimension Scoring Rubric

Score each lead 0–2 on every dimension. Maximum total: 10.

### 1. Role fit (0–2)

| Score | Criteria |
|---|---|
| 0 | Not a decision-maker or user. Wrong department entirely. |
| 1 | Adjacent role or influencer. Might champion internally. |
| 2 | Direct decision-maker or power user. Can sign up today. |

**High-signal titles:** Content Lead, Head of Content, Technical Writer, Product Manager, Product Marketer, Founder, Head of Growth, Developer Advocate, Documentation Engineer.

### 2. Company stage (0–2)

| Score | Criteria |
|---|---|
| 0 | Pre-revenue, idea-stage, or Fortune 500 enterprise. |
| 1 | Seed / Series A (small but funded) or late-stage enterprise with autonomous teams. |
| 2 | Series B–D. Growing team, documentation needs scaling, budget exists. |

**Sweet spot:** 20–200 employees, growing, hiring writers or content people.

### 3. Use case clarity (0–2)

| Score | Criteria |
|---|---|
| 0 | No obvious reason they'd need WordPilot. |
| 1 | General writing, content, or documentation need — plausible but unclear. |
| 2 | Clear pain point: scaling docs, AI writing workflow, structured content, multi-format output. |

**High-signal signals:** recent posts about AI writing tools, documentation challenges, content team scaling, markdown workflows.

### 4. Tool ecosystem (0–2)

| Score | Criteria |
|---|---|
| 0 | No relevant tools visible. Analogue workflow. |
| 1 | Uses general productivity tools (Notion, Google Docs, Confluence). |
| 2 | Already uses AI writing tools (ChatGPT, Claude, Jasper, Copy.ai), markdown editors, or Plate-based tools. |

**High-signal tools:** Notion AI, ChatGPT Plus/Pro, Claude, Jasper, Copy.ai, Obsidian, Plate.js, Slate.js, MDX, any "AI writing assistant" in their stack.

### 5. Reachability (0–2)

| Score | Criteria |
|---|---|
| 0 | No public email, no social presence, no way to contact. |
| 1 | Email discoverable. Light social activity. |
| 2 | Public email, active on LinkedIn or Twitter, recent content. Easy personalization hook. |

**High-signal platforms:** active LinkedIn presence, Twitter/X threads about their work, personal website with email, GitHub with public email, conference talks or podcasts.

## Score tiers

| Score | Tier | Label | Action |
|---|---|---|---|
| 8–10 | Hot | Priority outreach | Draft within 24 hours of research |
| 6–7 | Warm | Worth pursuing | Tailored email within the week |
| 4–5 | Cool | Low priority | Batch research; send if bandwidth |
| 1–3 | Weak | Marginal fit | Disqualify or park in Nurture |

## When to revise this ICP

- After 20 outreach emails: review response rates by score tier. Tighten or loosen.
- When the product changes: new features open new use cases and audiences.
- When you discover an unexpected convert: add that signal pattern to the ICP.
- Quarterly: review and refresh regardless.

FILE:reference/templates.md
# Email Templates

Templates are starting points, not finished products. Every email sent must include at least one personalization hook specific to the recipient. Never send a template as-is.

## Template rules

- Replace every `[bracket]` with real, specific details.
- Add at least one line that could only be written for this person.
- Keep it under 120 words.
- Light, curious tone. No pressure.
- Easy-to-ignore CTA. "No rush" is your friend.

## Outreach — Insight-led

Use when you found the lead through something they wrote or shared.

**Subject:** Your [post / thread / article] on [topic]

Hi [name],

Your [post / thread] on [specific topic] got me thinking — especially the bit about [specific detail].

I'm building [WordPilot.pro / a writing workspace that does X], and your take on [topic] maps closely to what we're working on.

Would love to hear how you're thinking about [related question]. No rush — just wanted to share while it was top of mind.

[Your name]

---

## Outreach — Question-led

Use when the lead's company or role suggests a specific problem.

**Subject:** Curious how [company] handles [problem]

Hi [name],

Quick question: how is [company] handling [specific problem or workflow] these days?

We've been working on [WordPilot.pro / a tool that helps with X], and I keep hearing from [similar roles / companies] that [pain point] is a real challenge.

Would love to hear if that maps to your world at all. Zero pitch — genuinely curious.

[Your name]

---

## Outreach — Connection-led

Use when you share mutual context: industry, background, tool, community.

**Subject:** [Mutual context] — quick question

Hi [name],

Saw we both [share mutual context: same industry / same tool / same community / same event]. Your work on [specific thing] caught my eye.

I'm working on [WordPilot.pro / brief one-line description], and I've been talking to [similar people / roles] about how they handle [problem].

Worth a 2-minute read? Happy to share more if it's interesting — no pressure either way.

[Your name]

---

## Follow-up #1 — Light bump (5–7 days after outreach)

**Subject:** Re: [original subject]

Hi [name],

Wanted to bump this in case it got buried. Would still love your take on [original hook / question].

No worries if the timing's off.

[Your name]

---

## Follow-up #2 — Last attempt (14 days after first follow-up)

**Subject:** Re: [original subject]

Hi [name],

One last ping — I'll leave you alone after this. If [topic / problem] is on your radar at any point, I'd be happy to share what we're building.

Either way, really respect the work you're doing at [company].

# Lead Generator & Tracker (WordPilot.pro)

Use this playbook to research, qualify, track, and professionally convert leads for WordPilot.pro — an AI-powered writing workspace. This skill operates on a **daily cadence**: each day you check in, WordPilot reports progress, researches new leads, advances existing ones, and produces an updated daily board.

This skill is designed for **sustained, professional lead generation** — not mass blasting. Every lead gets context, every outreach feels human, and every follow-up is tracked.

## Core Philosophy

1. **Research before reaching out.** Never cold-contact someone without understanding their context, work, and why WordPilot might genuinely help them.
2. **Value-first, never salesy.** Position WordPilot as a tool that solves real problems — not a "deal" to jump on.
3. **Slow is smooth.** The conversion pipeline is 5 stages; leads advance when they show real interest, not when a timer expires.
4. **Everything is tracked.** The `/leads/` workspace folder is the single source of truth.
5. **Daily accountability.** Every session produces a concrete update to the daily board.

## When to Apply

- User says "how's lead gen going?", "show me today's leads", "find new leads", "check the pipeline", or similar.
- User opens the workspace and the daily board needs updating.
- User asks to research a specific segment, industry, or persona.
- User wants to draft outreach to a specific lead or stage.
- User wants to review conversion metrics or pipeline health.

## Preconditions

- Gmail should be connected (via Integrations → Composio) for outreach and tracking. If not connected, research and qualification still proceed — but outreach steps will be drafted for review rather than sent.
- Google Sheets or Notion are optional but recommended for external CRM sync. If connected, leads can sync bidirectionally.
- Composio Search and Browser Tool are used for deep lead research — both are pre-connected on WordPilot.

## Conversion Pipeline (6 Stages)

Every lead moves through these stages. Movement between stages is deliberate, not automatic.

### Stage 1 — Discovered
Lead has been identified through research. Basic info captured: name, role, company, why they might need WordPilot. No outreach yet.

### Stage 2 — Researched  
Deep context gathered: recent work, pain points, public content, team size, tech stack, current tools. A "hook" identified — something specific that connects their work to WordPilot's value.

### Stage 3 — Qualified
Lead meets qualification criteria: decision-making authority or influence, active in relevant space (writing, documentation, content, dev tools), company has budget signals, and the fit is genuine — not forced.

### Stage 4 — Contacted
First outreach sent (email, social, or other channel). Message is personalized, references specific research, and opens a conversation — not a pitch.

### Stage 5 — Nurturing
Lead has responded or shown interest. In active conversation. Follow-ups are timely and value-adding. Goal: get them to try WordPilot.pro.

### Stage 6 — Converted
Lead has signed up, joined a waitlist, or committed to trying WordPilot. Hand-off complete. Track for referrals and case studies.

## Workspace Structure

All lead work lives under `/leads/`. Keep this structure clean and always up to date:

```
/leads/
├── daily-board.md          ← Today's todos, progress, and session log
├── pipeline.md             ← Full pipeline view: all leads by stage
├── research-methods.md     ← Research playbooks by persona/industry
├── templates.md            ← Outreach templates, follow-up patterns, DM scripts
├── archive/                ← Converted, dead, or dormant leads
│   └── 2026-05/
└── leads/                  ← Individual lead files (one per lead)
    └── john-doe.md
```

## Daily Cadence (The Loop)

When the user checks in each day (or you're invoked for lead work), follow this loop:

### 1) READ THE ROOM
- Read `/leads/daily-board.md` to understand yesterday's state and today's open items.
- Read `/leads/pipeline.md` to see current pipeline health.
- Check if Gmail/Sheets/Notion are connected (ask user to connect if needed for today's work).

### 2) PROCESS YESTERDAY'S OUTSTANDING
- Any follow-ups due today? Draft them.
- Any leads stuck in a stage too long? Note them and suggest next action.
- Any responses received since last session? Process them.

### 3) RESEARCH NEW LEADS (if pipeline needs filling)
- Pick 1–2 research segments (by persona, industry, or use case).
- Use Composio Search Web to find people/teams that match.
- For promising leads, deep-research with Fetch URL Content or Browser Tool.
- Create individual lead files in `/leads/leads/`.
- Add to pipeline at Stage 1 (Discovered).

### 4) ADVANCE EXISTING LEADS
- For Researched leads: qualify them against criteria. Move to Stage 3 or note why not.
- For Qualified leads: draft first outreach. If Gmail connected, offer to send.
- For Contacted leads: check if follow-up is due. Draft if so.
- For Nurturing leads: suggest next value-add (case study, feature highlight, direct invite).

### 5) UPDATE THE DAILY BOARD
- Write today's session summary to `/leads/daily-board.md`.
- Update pipeline stage counts.
- Set tomorrow's priority items.
- Mark todos as done.

### 6) REPORT TO USER
Summarize: what was done today, pipeline health (counts per stage), top 3 priority leads, and what's queued for tomorrow. Keep it concise but complete.

## Research Methodology

### Finding Leads (Composio Search Web)

Search by segment. Examples:
- `"technical writing" team lead "documentation" site:linkedin.com/in`
- `content strategist "AI writing" OR "AI content" startup`
- `developer advocate documentation tool "dev experience"`
- `head of content OR director of content SaaS 2025 2026`
- `"documentation as code" engineer OR architect OR lead`

Always search with recency and role qualifiers. Review citations for real people, not generic listicles.

### Deep Research (Fetch URL Content / Browser Tool)

For promising leads, research their:
- **Current role and company**: What do they do? Team size? Public projects?
- **Pain points**: Are they drowning in docs? Migrating tools? Scaling content?
- **Current stack**: What tools do they mention? Notion, Confluence, Google Docs, GitBook?
- **Public content**: Blog posts, talks, tweets, GitHub repos that show their thinking.
- **Hook**: Find one specific, genuine connection to WordPilot's value.

### Qualification Criteria

Score leads 1–5 on each (aim for 3+ overall):
- **Relevance**: Does their work intersect with writing, docs, content, or developer tools?
- **Authority**: Do they have decision power or influence over tooling?
- **Reach**: Do they have an audience, team, or public presence?
- **Timing**: Is there a signal they're looking for something new? (job change, tool migration, scaling pain)
- **Fit**: Would WordPilot genuinely help them? Don't force it.

## Outreach Principles

### Voice & Tone
- Professional, warm, curious — never pitchy.
- Lead with what you noticed about THEIR work.
- Position WordPilot as "something I thought you might find interesting" — not "something you need to buy."
- Respect their time. Short messages. Clear value. Easy to ignore.

### First Contact Template (Adapt, Don't Copy-Paste)

```
Subject: Your [specific work / post / talk] on [topic]

Hi [Name],

I came across your [post/talk/repo/work] on [specific topic] — really enjoyed 
[one specific insight you genuinely appreciated].

I work on WordPilot, an AI workspace for writing and documentation. Given your 
work on [their domain], I thought you might find it interesting — especially 
[one specific feature or angle that connects to their work].

No pitch — just wanted to share in case it's useful. Happy to give you early 
access if you'd like to try it.

Best,
[Your name]
```

### Follow-Up Principles
- Wait 5–7 days before following up.
- Add new value each time — a feature update, a case study, a relevant article.
- Never "just checking in" or "bumping this."
- After 3 unanswered messages, move to dormant. Revisit in 2–3 months with fresh context.

## Research Methods by Persona

Tailor search and outreach by persona. See `/leads/research-methods.md` for detailed playbooks. Quick reference:

| Persona | Where to Find | What to Lead With |
|---|---|---|
| **Technical Writer** | Write the Docs, LinkedIn, GitHub docs repos | WordPilot's MDX blocks, diagram support, version control |
| **Content Strategist** | Content marketing communities, Twitter/X, Medium | AI-assisted drafting, content pipelines, team workspaces |
| **Developer Advocate** | DevRel communities, conference talks, YouTube | Documentation generation, GitHub integration, API docs |
| **Engineering Manager** | Engineering blogs, HN, LinkedIn | Documentation workflows, team onboarding, knowledge management |
| **Founder / Indie Hacker** | Product Hunt, Indie Hackers, Twitter/X | All-in-one writing workspace, speed, shipping content faster |
| **Technical PM** | LinkedIn, product communities, Medium | Spec-to-documentation pipeline, PRDs, cross-functional docs |

## Tools Reference

### Composio Search Web (Primary Research)
```
COMPOSIO_SEARCH_WEB with query strings targeting specific personas and segments.
Review response.data.citations for real people/companies.
```

### Composio Fetch URL Content (Deep Research)
```
COMPOSIO_SEARCH_FETCH_URL_CONTENT on specific About/Team/Blog pages.
Extract context, not just contact info.
```

### Browser Tool (For Complex Sites)
```
BROWSER_TOOL_CREATE_TASK for LinkedIn profiles, dynamic pages, or sites 
that block simple fetches. Use WatchTask to poll results.
```

### Gmail (Outreach)
```
GMAIL_CREATE_EMAIL_DRAFT → review with user → GMAIL_SEND_EMAIL or GMAIL_SEND_DRAFT.
Always draft first, never auto-send without user review.
```

### Google Sheets / Notion (External CRM Sync)
```
GOOGLESHEETS_UPSERT_ROWS for spreadsheet-based CRM.
NOTION_UPSERT_ROW_DATABASE for Notion-based tracking.
Sync pipeline data when these are connected.
```

## Anti-Patterns (Do Not Do)

- **Never auto-send emails without user review.** Draft, show, get approval.
- **Never scrape personal emails from unauthorized sources.** Only use publicly available professional contact info or platforms where the person has shared their email for professional purposes.
- **Never send generic blast messages.** Every outreach must reference specific research.
- **Never over-research one lead.** 15–20 minutes max per lead for deep research. Move on.
- **Never leave the daily board empty.** Every session produces an update — even if it's "no new leads today, advanced 2 existing."
- **Never force-fit a lead.** If WordPilot isn't genuinely useful for someone, note it and move them out of the pipeline.
- **Never stalk or over-contact.** Max 3 unanswered messages, then move to dormant.

## Quality Standards

- Every lead file has a real hook — not just "they write things."
- Pipeline counts are accurate and updated same-session.
- Outreach drafts sound like a human wrote them — specifically for that person.
- Daily board is written so the user can scan it in 60 seconds.
- Research is documented, not just remembered.
- If Gmail/Sheets/Notion aren't connected, say so — and still do everything possible without them.

## Getting Started (First Session)

When this skill is first invoked and there's no `/leads/` folder yet:

1. Create the full workspace structure under `/leads/`.
2. Write the initial `/leads/daily-board.md` with today's date.
3. Write the initial `/leads/pipeline.md` with empty stage tables.
4. Write `/leads/research-methods.md` with detailed persona playbooks.
5. Write `/leads/templates.md` with outreach patterns.
6. Ask the user: "What segment or persona should I research first?" — then begin.

## First Contact Templates

### For Technical Writers
```
Subject: Your [talk/post] on [specific documentation topic]

Hi [Name],

I caught your [talk/post] on [topic] — the point about [specific insight] 
really landed. Documentation teams deal with that exact tension between 
richness and maintainability.

I'm working on WordPilot, an AI writing workspace that handles that well — 
it supports advanced MDX blocks (diagrams, equations, columns) in plain 
markdown, so docs stay readable AND rich. No lock-in, no proprietary format.

No pitch — just thought you might find the approach interesting given your 
work. Happy to share more if you're curious.

Best,
[Your name]
```

### For Content Strategists
```
Subject: Your piece on [content challenge]

Hi [Name],

Really enjoyed your piece on [specific content challenge] — the [specific 
point] matches what a lot of content teams are running into right now.

I work on WordPilot, an AI workspace that helps content teams draft, review, 
and publish faster. The AI doesn't replace writers — it handles the 
repetitive parts so strategists can focus on strategy.

Would be happy to show you how it works if you're interested. No sales 
pressure — just thought it aligned with your thinking.

Best,
[Your name]
```

### For Developer Advocates
```
Subject: Your tutorial on [topic] — sharp work

Hi [Name],

Your tutorial on [topic] was excellent — particularly the [specific part]. 
Creating that kind of content at quality takes real time.

I'm building WordPilot, and one thing we focused on was making technical 
content creation faster: diagrams right in markdown (Mermaid/Kroki), 
GitHub-integrated docs, and AI that actually understands code.

Given how much technical content you produce, I thought you might find it 
useful. Happy to give you early access if you want to try it.

Cheers,
[Your name]
```

### For Engineering Managers
```
Subject: Documentation workflows and developer experience

Hi [Name],

I read about [company/team]'s approach to [engineering practice] — 
impressive how you handle [specific challenge] at scale.

One area I've been thinking about is documentation friction in engineering 
teams. We built WordPilot specifically so docs don't feel like a separate 
chore — markdown-native, GitHub-connected, with AI that helps without 
getting in the way.

No pitch — just curious if documentation workflow is something on your radar. 
Happy to share what we're building if relevant.

Best,
[Your name]
```

### For Founders / Indie Hackers
```
Subject: Writing tool you might find useful

Hi [Name],

Been following your build on [platform] — really impressive progress on 
[product]. The way you handle [specific thing] is smart.

I built WordPilot as an AI writing workspace — it replaces the patchwork of 
Google Docs, Notion, and markdown editors with one tool that actually works 
for real writing. Might be useful for your content, docs, or even product specs.

No pressure — just thought it might save you some tool-switching time. Happy 
to share access if you want to kick the tires.

Cheers,
[Your name]
```

### For Technical Product Managers
```
Subject: Your approach to [product practice]

Hi [Name],

Enjoyed reading about how you handle [specific product workflow] at 
[company] — the [specific insight] is something more teams should adopt.

I work on WordPilot, an AI writing workspace. One thing it handles 
particularly well is the spec-to-documentation pipeline — rich markdown 
with diagrams and equations, collaboration built in, and no proprietary 
format lock-in.

Thought it might be relevant given your focus on [their domain]. Happy to 
show you if you're interested.

Best,
[Your name]
```

## Follow-Up Patterns

### Follow-Up 1 (5–7 days after first contact)
```
Subject: Re: Your [original topic]

Hi [Name],

Just following up on my previous note — I know inboxes get busy.

I also wanted to mention [one new specific thing] about WordPilot since I 
last wrote: [feature update, new capability, relevant case study].

No rush — just wanted to keep it on your radar in case it's useful.

Best,
[Your name]
```

### Follow-Up 2 (5–7 days after follow-up 1)
```
Subject: Quick thought on [their domain]

Hi [Name],

I came across [relevant article / trend / insight] and immediately thought of 
your work on [their topic]. [One sentence connecting the insight to them].

WordPilot handles this well — specifically [relevant feature]. I won't keep 
following up after this, but wanted to share the connection.

If it ever becomes relevant, my inbox is open.

Best,
[Your name]
```

### Follow-Up 3 — Final (5–7 days after follow-up 2)
```
Subject: Re: Quick thought on [their domain]

Hi [Name],

Last note from me — I'll leave you be after this.

If you ever want to explore WordPilot, the door's open. We're building 
something genuinely useful for [their persona], and I think you'd find it 
interesting.

No reply needed — just wanted to leave that on the table.

Best,
[Your name]
```

---

## DM / Social Outreach (Twitter, LinkedIn)

### LinkedIn Connection Note
```
Hi [Name] — I came across your [work/talk/post] on [topic] and was really 
impressed by [specific insight]. I work on an AI writing tool that touches 
similar ground. Would love to connect.
```

### Twitter DM (if already connected)
```
Hey [Name] — loved your [post/thread] on [topic]. Working on an AI writing 
workspace that handles [related thing] really well. Thought you might find 
it interesting: [link]. No pitch — just sharing.
```

---

## Response Handling

### If They Reply "Not interested"
```
Thanks for letting me know, [Name]. Totally understand — appreciate you 
taking the time to reply. All the best with [their work/company].
```

### If They Reply "Tell me more"
Send a concise 3–4 sentence overview of WordPilot with one specific feature 
relevant to their work. End with an invitation to try it or schedule a 
quick walkthrough.

### If They Reply "Trying it out"
Celebrate internally (move to Stage 5 — Nurturing). Send a warm welcome 
with a getting-started tip relevant to their use case. Offer to answer 
questions.

## Anti-Patterns (Never Do These)

- ❌ "Just following up!" with no new value
- ❌ "We're disrupting the [X] space" jargon
- ❌ Long emails — keep under 150 words
- ❌ HTML-heavy or image-heavy emails
- ❌ Asking for a call in the first message
- ❌ "Limited time offer" or urgency tactics
- ❌ Name-dropping without permission
- ❌ Assuming their pain points without research

I want you to act as a Micro-SaaS 'Vibecoder' Architect and Senior Product Manager. I will provide you with a problem I want to solve, my target user, and my preferred AI coding environment. Your goal is to map out a clear, actionable blueprint for building an AI-powered MVP.

For this request, you must provide:
1) **The Core Loop:** A step-by-step breakdown of the single most important user journey (The 'Aha' Moment).
2) **AI Integration Strategy:** Specifically how LLMs or AI APIs should be utilized (e.g., prompt chaining, RAG, direct API calls) to solve the core problem efficiently.
3) **The 'Vibecoder' Tech Stack:** Recommend the fastest path to deployment (frontend, backend, database, and hosting) suited for rapid AI-assisted coding.
4) **MVP Scope Reduction:** Identify 3 features that founders usually build first but must be EXCLUDED from this MVP to launch faster.
5) **The Kickoff Prompt:** Write the exact, highly detailed prompt I should paste into my AI coding assistant to generate the foundational boilerplate for this app.

Do not break character. Be highly technical but ruthlessly focused on shipping fast.

Problem to Solve: Problem_to_Solve
Target User: Target_User
Preferred AI Coding Tool: Cursor, v0, Lovable, Bolt.new, etc.

You are a Senior Product Manager with expertise in writing comprehensive Product Requirements Documents (PRDs). We are going to collaborate on writing a PRD for: [your_productfeature_idea]

  IMPORTANT: Before we begin drafting, please ask me 5-8 clarifying questions to gather essential context:
  - Product vision and strategic alignment
  - Target users and their pain points
  - Success metrics and business objectives
  - Technical constraints or preferences
  - Scope boundaries (MVP vs future releases)

  Once I answer, we'll create the PRD in phases. For each section, use this structure:

  **Phase 1: Problem & Context**
  - Problem statement (data-backed)
  - User personas and scenarios
  - Market/competitive context
  - Success metrics (specific, measurable)

  **Phase 2: Solution & Requirements**
  - Product overview and key features
  - User stories in Given/When/Then format
  - Functional requirements (MVP vs future)
  - Non-functional requirements (performance, security, scalability)

  **Phase 3: Technical & Implementation**
  - Technical architecture considerations
  - Dependencies and integrations
  - Implementation phases with testable milestones
  - Risk assessment and mitigation

  **Output Guidelines:**
  - Use consistent patterns (if acceptance criteria starts with verbs, maintain throughout)
  - Separate functional from non-functional requirements
  - For AI features: specify accuracy thresholds (e.g., ≥90%), hallucination limits (<2%)
  - Include confidence levels for assumptions
  - Prefer long-form written sections over bullet points for clarity

  Context about my company/project:
  add_your_company_context_charter_tech_stack_team_size_etc

  Let's start with your clarifying questions.

## Core Principles for Prompt Engineering

### 1. Clarity and Directness
- **Be explicit**: State exactly what you want Claude to do
- **Avoid ambiguity**: Use precise language that leaves no room for misinterpretation
- **Use concrete examples**: Show, don't just tell
- **Structure logically**: Organize information hierarchically

### 2. Conciseness
- **Respect context windows**: Keep prompts focused and relevant
- **Remove redundancy**: Eliminate unnecessary repetition
- **Progressive disclosure**: Provide details only when needed
- **Token efficiency**: Optimize for both quality and cost

### 3. Appropriate Degrees of Freedom
- **Define constraints**: Set clear boundaries for what Claude should/shouldn't do
- **Specify format**: Be explicit about desired output format
- **Set scope**: Clearly define what's in and out of scope
- **Balance flexibility**: Allow room for Claude's reasoning while maintaining control

## Advanced Prompt Engineering Techniques

### Chain-of-Thought (CoT) Prompting
Encourage step-by-step reasoning for complex tasks:
```
"Let's think through this step by step:
1. First, identify...
2. Then, analyze...
3. Finally, conclude..."
```

### Few-Shot Prompting
Use examples to guide behavior:
- **1-shot**: Single example for simple tasks
- **2-shot**: Two examples for moderate complexity
- **Multi-shot**: Multiple examples for complex patterns

### XML Tags for Structure
Use XML tags for clarity and parsing:
```xml
<task>
  <objective>What you want done</objective>
  <constraints>Limitations and rules</constraints>
  <format>Expected output format</format>
</task>
```

### Role-Based Prompting
Assign expertise to Claude:
```
"You are an expert prompt engineer with deep knowledge of...
Your task is to..."
```

### Prefilling
Start Claude's response to guide format:
```
"Here's my analysis:

Key findings:"
```

### Prompt Chaining
Break complex tasks into sequential prompts:
1. Prompt 1: Analyze input
2. Prompt 2: Process analysis
3. Prompt 3: Generate output

## Custom Instructions & System Prompts

### System Prompt Design
- **Define role**: What expertise should Claude embody?
- **Set tone**: What communication style is appropriate?
- **Establish constraints**: What should Claude avoid?
- **Clarify scope**: What's the domain of expertise?

### Behavioral Guidelines
- **Do's**: Specific behaviors to encourage
- **Don'ts**: Specific behaviors to avoid
- **Edge cases**: How to handle unusual situations
- **Escalation**: When to ask for clarification

## Skill Structure Best Practices

### Writing Effective Descriptions
- **First line**: Clear, concise summary (max 1024 chars)
- **Specificity**: Indicate exact capabilities
- **Use cases**: Mention primary applications
- **Avoid vagueness**: Don't use "helps with" or "assists in"

### Progressive Disclosure Patterns

**Pattern 1: High-level guide with references**
- Start with overview
- Link to detailed sections
- Organize by complexity

**Pattern 2: Domain-specific organization**
- Group by use case
- Separate concerns
- Clear navigation

## 1. Chain-of-Thought (CoT) Prompting

### What It Is
Encouraging Claude to break down complex reasoning into explicit steps before providing a final answer.

### When to Use
- Complex reasoning tasks
- Multi-step problems
- Tasks requiring justification
- When consistency matters

### Basic Structure
```
Let's think through this step by step:

Step 1: [First logical step]
Step 2: [Second logical step]
Step 3: [Third logical step]

Therefore: [Conclusion]
```

### Example
```
Problem: A store sells apples for $2 each and oranges for $3 each. 
If I buy 5 apples and 3 oranges, how much do I spend?

Let's think through this step by step:

Step 1: Calculate apple cost
- 5 apples × $2 per apple = $10

Step 2: Calculate orange cost
- 3 oranges × $3 per orange = $9

Step 3: Calculate total
- $10 + $9 = $19

Therefore: You spend $19 total.
```

### Benefits
- More accurate reasoning
- Easier to identify errors
- Better for complex problems
- More transparent logic

## 2. Few-Shot Learning

### What It Is
Providing examples to guide Claude's behavior without explicit instructions.

```
Example: "Happy" → Positive
Now classify: "Terrible" →
```

#### 2-Shot (Two Examples)
Best for: Moderate complexity
```
Example 1: "Great product!" → Positive
Example 2: "Doesn't work well" → Negative
Now classify: "It's okay" →
```

#### Multi-Shot (Multiple Examples)
Best for: Complex patterns, edge cases
```
Example 1: "Love it!" → Positive
Example 2: "Hate it" → Negative
Example 3: "It's fine" → Neutral
Example 4: "Could be better" → Neutral
Example 5: "Amazing!" → Positive
Now classify: "Not bad" →
```

### Best Practices
- Use diverse examples
- Include edge cases
- Show correct format

```
Extract key information from this document:
- Main topic
- Key points (bullet list)
- Important dates
- Relevant entities

Format as JSON.
```

**Prompt 2: Analyze Extracted Data**
```
Analyze this extracted information:
[JSON from Prompt 1]

Identify:
- Relationships between entities
- Temporal patterns
- Significance of each point
```

**Prompt 3: Generate Summary**
```
Based on this analysis:
[Analysis from Prompt 2]

Create an executive summary that:

Then provide: Relevant details
Finally include: Edge cases and exceptions
```

#### Hierarchical Organization
```
Level 1: Core concept
├── Level 2: Key components
│   ├── Level 3: Specific details
│   └── Level 3: Implementation notes
└── Level 2: Related concepts
```

#### Conditional Information
```
If [condition], include [information]
Else, skip [information]

This reduces unnecessary context.
```

### Best Practices
- Include only necessary context
- Organize hierarchically
- Use references for detailed info
- Summarize before details
- Link related concepts

## 8. Multimodal Prompting

### Vision Prompting

#### Structure
```

# MCP Server Development Guide

## Overview

Create MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. The quality of an MCP server is measured by how well it enables LLMs to accomplish real-world tasks.

---

# Process

## 🚀 High-Level Workflow

Creating a high-quality MCP server involves four main phases:

### Phase 1: Deep Research and Planning

#### 1.1 Understand Modern MCP Design

**API Coverage vs. Workflow Tools:**
Balance comprehensive API endpoint coverage with specialized workflow tools. Workflow tools can be more convenient for specific tasks, while comprehensive coverage gives agents flexibility to compose operations. Performance varies by client—some clients benefit from code execution that combines basic tools, while others work better with higher-level workflows. When uncertain, prioritize comprehensive API coverage.

**Tool Naming and Discoverability:**
Clear, descriptive tool names help agents find the right tools quickly. Use consistent prefixes (e.g., `github_create_issue`, `github_list_repos`) and action-oriented naming.

**Context Management:**
Agents benefit from concise tool descriptions and the ability to filter/paginate results. Design tools that return focused, relevant data. Some clients support code execution which can help agents filter and process data efficiently.

**Actionable Error Messages:**
Error messages should guide agents toward solutions with specific suggestions and next steps.

#### 1.2 Study MCP Protocol Documentation

**Navigate the MCP specification:**

Start with the sitemap to find relevant pages: `https://modelcontextprotocol.io/sitemap.xml`

Then fetch specific pages with `.md` suffix for markdown format (e.g., `https://modelcontextprotocol.io/specification/draft.md`).

Key pages to review:
- Specification overview and architecture
- Transport mechanisms (streamable HTTP, stdio)
- Tool, resource, and prompt definitions

#### 1.3 Study Framework Documentation

**Recommended stack:**
- **Language**: TypeScript (high-quality SDK support and good compatibility in many execution environments e.g. MCPB. Plus AI models are good at generating TypeScript code, benefiting from its broad usage, static typing and good linting tools)
- **Transport**: Streamable HTTP for remote servers, using stateless JSON (simpler to scale and maintain, as opposed to stateful sessions and streaming responses). stdio for local servers.

**Load framework documentation:**

- **MCP Best Practices**: [📋 View Best Practices](./reference/mcp_best_practices.md) - Core guidelines

**For TypeScript (recommended):**
- **TypeScript SDK**: Use WebFetch to load `https://raw.githubusercontent.com/modelcontextprotocol/typescript-sdk/main/README.md`
- [⚡ TypeScript Guide](./reference/node_mcp_server.md) - TypeScript patterns and examples

**For Python:**
- **Python SDK**: Use WebFetch to load `https://raw.githubusercontent.com/modelcontextprotocol/python-sdk/main/README.md`
- [🐍 Python Guide](./reference/python_mcp_server.md) - Python patterns and examples

#### 1.4 Plan Your Implementation

**Understand the API:**
Review the service's API documentation to identify key endpoints, authentication requirements, and data models. Use web search and WebFetch as needed.

**Tool Selection:**
Prioritize comprehensive API coverage. List endpoints to implement, starting with the most common operations.

---

### Phase 2: Implementation

#### 2.1 Set Up Project Structure

See language-specific guides for project setup:
- [⚡ TypeScript Guide](./reference/node_mcp_server.md) - Project structure, package.json, tsconfig.json
- [🐍 Python Guide](./reference/python_mcp_server.md) - Module organization, dependencies

#### 2.2 Implement Core Infrastructure

Create shared utilities:
- API client with authentication
- Error handling helpers
- Response formatting (JSON/Markdown)
- Pagination support

#### 2.3 Implement Tools

For each tool:

**Input Schema:**
- Use Zod (TypeScript) or Pydantic (Python)
- Include constraints and clear descriptions
- Add examples in field descriptions

**Output Schema:**
- Define `outputSchema` where possible for structured data
- Use `structuredContent` in tool responses (TypeScript SDK feature)
- Helps clients understand and process tool outputs

**Tool Description:**
- Concise summary of functionality
- Parameter descriptions
- Return type schema

**Implementation:**
- Async/await for I/O operations
- Proper error handling with actionable messages
- Support pagination where applicable
- Return both text content and structured data when using modern SDKs

**Annotations:**
- `readOnlyHint`: true/false
- `destructiveHint`: true/false
- `idempotentHint`: true/false
- `openWorldHint`: true/false

---

### Phase 3: Review and Test

#### 3.1 Code Quality

Review for:
- No duplicated code (DRY principle)
- Consistent error handling
- Full type coverage
- Clear tool descriptions

#### 3.2 Build and Test

**TypeScript:**
- Run `npm run build` to verify compilation
- Test with MCP Inspector: `npx @modelcontextprotocol/inspector`

**Python:**
- Verify syntax: `python -m py_compile your_server.py`
- Test with MCP Inspector

See language-specific guides for detailed testing approaches and quality checklists.

---

### Phase 4: Create Evaluations

After implementing your MCP server, create comprehensive evaluations to test its effectiveness.

**Load [✅ Evaluation Guide](./reference/evaluation.md) for complete evaluation guidelines.**

#### 4.1 Understand Evaluation Purpose

Use evaluations to test whether LLMs can effectively use your MCP server to answer realistic, complex questions.

#### 4.2 Create 10 Evaluation Questions

To create effective evaluations, follow the process outlined in the evaluation guide:

1. **Tool Inspection**: List available tools and understand their capabilities
2. **Content Exploration**: Use READ-ONLY operations to explore available data
3. **Question Generation**: Create 10 complex, realistic questions
4. **Answer Verification**: Solve each question yourself to verify answers

#### 4.3 Evaluation Requirements

Ensure each question is:
- **Independent**: Not dependent on other questions
- **Read-only**: Only non-destructive operations required
- **Complex**: Requiring multiple tool calls and deep exploration
- **Realistic**: Based on real use cases humans would care about
- **Verifiable**: Single, clear answer that can be verified by string comparison
- **Stable**: Answer won't change over time

#### 4.4 Output Format

Create an XML file with this structure:

```xml
<evaluation>
  <qa_pair>
    <question>Find discussions about AI model launches with animal codenames. One model needed a specific safety designation that uses the format ASL-X. What number X was being determined for the model named after a spotted wild cat?</question>
    <answer>3</answer>
  </qa_pair>
<!-- More qa_pairs... -->
</evaluation>
```

# MCP Server Best Practices

## Quick Reference

### Server Naming
- **Python**: `{service}_mcp` (e.g., `slack_mcp`)
- **Node/TypeScript**: `{service}-mcp-server` (e.g., `slack-mcp-server`)

### Tool Naming
- Use snake_case with service prefix
- Format: `{service}_{action}_{resource}`
- Example: `slack_send_message`, `github_create_issue`

### Response Formats
- Support both JSON and Markdown formats
- JSON for programmatic processing
- Markdown for human readability

### Pagination
- Always respect `limit` parameter
- Return `has_more`, `next_offset`, `total_count`
- Default to 20-50 items

### Transport
- **Streamable HTTP**: For remote servers, multi-client scenarios
- **stdio**: For local integrations, command-line tools
- Avoid SSE (deprecated in favor of streamable HTTP)

---

## Server Naming Conventions

Follow these standardized naming patterns:

**Python**: Use format `{service}_mcp` (lowercase with underscores)
- Examples: `slack_mcp`, `github_mcp`, `jira_mcp`

**Node/TypeScript**: Use format `{service}-mcp-server` (lowercase with hyphens)
- Examples: `slack-mcp-server`, `github-mcp-server`, `jira-mcp-server`

The name should be general, descriptive of the service being integrated, easy to infer from the task description, and without version numbers.

---

## Tool Naming and Design

### Tool Naming

1. **Use snake_case**: `search_users`, `create_project`, `get_channel_info`
2. **Include service prefix**: Anticipate that your MCP server may be used alongside other MCP servers
   - Use `slack_send_message` instead of just `send_message`
   - Use `github_create_issue` instead of just `create_issue`
3. **Be action-oriented**: Start with verbs (get, list, search, create, etc.)
4. **Be specific**: Avoid generic names that could conflict with other servers

### Tool Design

- Tool descriptions must narrowly and unambiguously describe functionality
- Descriptions must precisely match actual functionality
- Provide tool annotations (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- Keep tool operations focused and atomic

---

## Response Formats

All tools that return data should support multiple formats:

### JSON Format (`response_format="json"`)
- Machine-readable structured data
- Include all available fields and metadata
- Consistent field names and types
- Use for programmatic processing

### Markdown Format (`response_format="markdown"`, typically default)
- Human-readable formatted text
- Use headers, lists, and formatting for clarity
- Convert timestamps to human-readable format
- Show display names with IDs in parentheses
- Omit verbose metadata

---

## Pagination

For tools that list resources:

- **Always respect the `limit` parameter**
- **Implement pagination**: Use `offset` or cursor-based pagination
- **Return pagination metadata**: Include `has_more`, `next_offset`/`next_cursor`, `total_count`
- **Never load all results into memory**: Especially important for large datasets
- **Default to reasonable limits**: 20-50 items is typical

Example pagination response:
```json
{
  "total": 150,
  "count": 20,
  "offset": 0,
  "items": [...],
  "has_more": true,
  "next_offset": 20
}
```

---

## Transport Options

### Streamable HTTP

**Best for**: Remote servers, web services, multi-client scenarios

**Characteristics**:
- Bidirectional communication over HTTP
- Supports multiple simultaneous clients
- Can be deployed as a web service
- Enables server-to-client notifications

**Use when**:
- Serving multiple clients simultaneously
- Deploying as a cloud service
- Integration with web applications

### stdio

**Best for**: Local integrations, command-line tools

**Characteristics**:
- Standard input/output stream communication
- Simple setup, no network configuration needed
- Runs as a subprocess of the client

**Use when**:
- Building tools for local development environments
- Integrating with desktop applications
- Single-user, single-session scenarios

**Note**: stdio servers should NOT log to stdout (use stderr for logging)

### Transport Selection

| Criterion | stdio | Streamable HTTP |
|-----------|-------|-----------------|
| **Deployment** | Local | Remote |
| **Clients** | Single | Multiple |
| **Complexity** | Low | Medium |
| **Real-time** | No | Yes |

---

## Security Best Practices

### Authentication and Authorization

**OAuth 2.1**:
- Use secure OAuth 2.1 with certificates from recognized authorities
- Validate access tokens before processing requests
- Only accept tokens specifically intended for your server

**API Keys**:
- Store API keys in environment variables, never in code
- Validate keys on server startup
- Provide clear error messages when authentication fails

### Input Validation

- Sanitize file paths to prevent directory traversal
- Validate URLs and external identifiers
- Check parameter sizes and ranges
- Prevent command injection in system calls
- Use schema validation (Pydantic/Zod) for all inputs

### Error Handling

- Don't expose internal errors to clients
- Log security-relevant errors server-side
- Provide helpful but not revealing error messages
- Clean up resources after errors

### DNS Rebinding Protection

For streamable HTTP servers running locally:
- Enable DNS rebinding protection
- Validate the `Origin` header on all incoming connections
- Bind to `127.0.0.1` rather than `0.0.0.0`

---

## Tool Annotations

Provide annotations to help clients understand tool behavior:

| Annotation | Type | Default | Description |
|-----------|------|---------|-------------|
| `readOnlyHint` | boolean | false | Tool does not modify its environment |
| `destructiveHint` | boolean | true | Tool may perform destructive updates |
| `idempotentHint` | boolean | false | Repeated calls with same args have no additional effect |
| `openWorldHint` | boolean | true | Tool interacts with external entities |

**Important**: Annotations are hints, not security guarantees. Clients should not make security-critical decisions based solely on annotations.

---

## Error Handling

- Use standard JSON-RPC error codes
- Report tool errors within result objects (not protocol-level errors)
- Provide helpful, specific error messages with suggested next steps
- Don't expose internal implementation details
- Clean up resources properly on errors

Example error handling:
```typescript
try {
  const result = performOperation();
  return { content: [{ type: "text", text: result }] };
} catch (error) {
  return {
    isError: true,
    content: [{
      type: "text",
      text: `Error: error.message. Try using filter='active_only' to reduce results.`
    }]
  };
}
```

---

## Testing Requirements

Comprehensive testing should cover:

- **Functional testing**: Verify correct execution with valid/invalid inputs
- **Integration testing**: Test interaction with external systems
- **Security testing**: Validate auth, input sanitization, rate limiting
- **Performance testing**: Check behavior under load, timeouts
- **Error handling**: Ensure proper error reporting and cleanup

---

## Documentation Requirements

- Provide clear documentation of all tools and capabilities
- Include working examples (at least 3 per major feature)
- Document security considerations
- Specify required permissions and access levels
- Document rate limits and performance characteristics
FILE:reference/evaluation.md
# MCP Server Evaluation Guide

## Overview

This document provides guidance on creating comprehensive evaluations for MCP servers. Evaluations test whether LLMs can effectively use your MCP server to answer realistic, complex questions using only the tools provided.

---

## Quick Reference

### Evaluation Requirements
- Create 10 human-readable questions
- Questions must be READ-ONLY, INDEPENDENT, NON-DESTRUCTIVE
- Each question requires multiple tool calls (potentially dozens)
- Answers must be single, verifiable values
- Answers must be STABLE (won't change over time)

### Output Format
```xml
<evaluation>
   <qa_pair>
      <question>Your question here</question>
      <answer>Single verifiable answer</answer>
   </qa_pair>
</evaluation>
```

---

## Purpose of Evaluations

The measure of quality of an MCP server is NOT how well or comprehensively the server implements tools, but how well these implementations (input/output schemas, docstrings/descriptions, functionality) enable LLMs with no other context and access ONLY to the MCP servers to answer realistic and difficult questions.

## Evaluation Overview

Create 10 human-readable questions requiring ONLY READ-ONLY, INDEPENDENT, NON-DESTRUCTIVE, and IDEMPOTENT operations to answer. Each question should be:
- Realistic
- Clear and concise
- Unambiguous
- Complex, requiring potentially dozens of tool calls or steps
- Answerable with a single, verifiable value that you identify in advance

## Question Guidelines

### Core Requirements

1. **Questions MUST be independent**
   - Each question should NOT depend on the answer to any other question
   - Should not assume prior write operations from processing another question

2. **Questions MUST require ONLY NON-DESTRUCTIVE AND IDEMPOTENT tool use**
   - Should not instruct or require modifying state to arrive at the correct answer

3. **Questions must be REALISTIC, CLEAR, CONCISE, and COMPLEX**
   - Must require another LLM to use multiple (potentially dozens of) tools or steps to answer

### Complexity and Depth

4. **Questions must require deep exploration**
   - Consider multi-hop questions requiring multiple sub-questions and sequential tool calls
   - Each step should benefit from information found in previous questions

5. **Questions may require extensive paging**
   - May need paging through multiple pages of results
   - May require querying old data (1-2 years out-of-date) to find niche information
   - The questions must be DIFFICULT

6. **Questions must require deep understanding**
   - Rather than surface-level knowledge
   - May pose complex ideas as True/False questions requiring evidence
   - May use multiple-choice format where LLM must search different hypotheses

7. **Questions must not be solvable with straightforward keyword search**
   - Do not include specific keywords from the target content
   - Use synonyms, related concepts, or paraphrases
   - Require multiple searches, analyzing multiple related items, extracting context, then deriving the answer

### Tool Testing

8. **Questions should stress-test tool return values**
   - May elicit tools returning large JSON objects or lists, overwhelming the LLM
   - Should require understanding multiple modalities of data:
     - IDs and names
     - Timestamps and datetimes (months, days, years, seconds)
     - File IDs, names, extensions, and mimetypes
     - URLs, GIDs, etc.
   - Should probe the tool's ability to return all useful forms of data

9. **Questions should MOSTLY reflect real human use cases**
   - The kinds of information retrieval tasks that HUMANS assisted by an LLM would care about

10. **Questions may require dozens of tool calls**
    - This challenges LLMs with limited context
    - Encourages MCP server tools to reduce information returned

11. **Include ambiguous questions**
    - May be ambiguous OR require difficult decisions on which tools to call
    - Force the LLM to potentially make mistakes or misinterpret
    - Ensure that despite AMBIGUITY, there is STILL A SINGLE VERIFIABLE ANSWER

### Stability

12. **Questions must be designed so the answer DOES NOT CHANGE**
    - Do not ask questions that rely on "current state" which is dynamic
    - For example, do not count:
      - Number of reactions to a post
      - Number of replies to a thread
      - Number of members in a channel

13. **DO NOT let the MCP server RESTRICT the kinds of questions you create**
    - Create challenging and complex questions
    - Some may not be solvable with the available MCP server tools
    - Questions may require specific output formats (datetime vs. epoch time, JSON vs. MARKDOWN)
    - Questions may require dozens of tool calls to complete

## Answer Guidelines

### Verification

1. **Answers must be VERIFIABLE via direct string comparison**
   - If the answer can be re-written in many formats, clearly specify the output format in the QUESTION
   - Examples: "Use YYYY/MM/DD.", "Respond True or False.", "Answer A, B, C, or D and nothing else."
   - Answer should be a single VERIFIABLE value such as:
     - User ID, user name, display name, first name, last name
     - Channel ID, channel name
     - Message ID, string
     - URL, title
     - Numerical quantity
     - Timestamp, datetime
     - Boolean (for True/False questions)
     - Email address, phone number
     - File ID, file name, file extension
     - Multiple choice answer
   - Answers must not require special formatting or complex, structured output
   - Answer will be verified using DIRECT STRING COMPARISON

### Readability

2. **Answers should generally prefer HUMAN-READABLE formats**
   - Examples: names, first name, last name, datetime, file name, message string, URL, yes/no, true/false, a/b/c/d
   - Rather than opaque IDs (though IDs are acceptable)
   - The VAST MAJORITY of answers should be human-readable

### Stability

3. **Answers must be STABLE/STATIONARY**
   - Look at old content (e.g., conversations that have ended, projects that have launched, questions answered)
   - Create QUESTIONS based on "closed" concepts that will always return the same answer
   - Questions may ask to consider a fixed time window to insulate from non-stationary answers
   - Rely on context UNLIKELY to change
   - Example: if finding a paper name, be SPECIFIC enough so answer is not confused with papers published later

4. **Answers must be CLEAR and UNAMBIGUOUS**
   - Questions must be designed so there is a single, clear answer
   - Answer can be derived from using the MCP server tools

### Diversity

5. **Answers must be DIVERSE**
   - Answer should be a single VERIFIABLE value in diverse modalities and formats
   - User concept: user ID, user name, display name, first name, last name, email address, phone number
   - Channel concept: channel ID, channel name, channel topic
   - Message concept: message ID, message string, timestamp, month, day, year

6. **Answers must NOT be complex structures**
   - Not a list of values
   - Not a complex object
   - Not a list of IDs or strings
   - Not natural language text
   - UNLESS the answer can be straightforwardly verified using DIRECT STRING COMPARISON
   - And can be realistically reproduced
   - It should be unlikely that an LLM would return the same list in any other order or format

## Evaluation Process

### Step 1: Documentation Inspection

Read the documentation of the target API to understand:
- Available endpoints and functionality
- If ambiguity exists, fetch additional information from the web
- Parallelize this step AS MUCH AS POSSIBLE
- Ensure each subagent is ONLY examining documentation from the file system or on the web

### Step 2: Tool Inspection

List the tools available in the MCP server:
- Inspect the MCP server directly
- Understand input/output schemas, docstrings, and descriptions
- WITHOUT calling the tools themselves at this stage

### Step 3: Developing Understanding

Repeat steps 1 & 2 until you have a good understanding:
- Iterate multiple times
- Think about the kinds of tasks you want to create
- Refine your understanding
- At NO stage should you READ the code of the MCP server implementation itself
- Use your intuition and understanding to create reasonable, realistic, but VERY challenging tasks

### Step 4: Read-Only Content Inspection

After understanding the API and tools, USE the MCP server tools:
- Inspect content using READ-ONLY and NON-DESTRUCTIVE operations ONLY
- Goal: identify specific content (e.g., users, channels, messages, projects, tasks) for creating realistic questions
- Should NOT call any tools that modify state
- Will NOT read the code of the MCP server implementation itself
- Parallelize this step with individual sub-agents pursuing independent explorations
- Ensure each subagent is only performing READ-ONLY, NON-DESTRUCTIVE, and IDEMPOTENT operations
- BE CAREFUL: SOME TOOLS may return LOTS OF DATA which would cause you to run out of CONTEXT
- Make INCREMENTAL, SMALL, AND TARGETED tool calls for exploration
- In all tool call requests, use the `limit` parameter to limit results (<10)
- Use pagination

### Step 5: Task Generation

After inspecting the content, create 10 human-readable questions:
- An LLM should be able to answer these with the MCP server
- Follow all question and answer guidelines above

## Output Format

Each QA pair consists of a question and an answer. The output should be an XML file with this structure:

```xml
<evaluation>
   <qa_pair>
      <question>Find the project created in Q2 2024 with the highest number of completed tasks. What is the project name?</question>
      <answer>Website Redesign</answer>
   </qa_pair>
   <qa_pair>
      <question>Search for issues labeled as "bug" that were closed in March 2024. Which user closed the most issues? Provide their username.</question>
      <answer>sarah_dev</answer>
   </qa_pair>
   <qa_pair>
      <question>Look for pull requests that modified files in the /api directory and were merged between January 1 and January 31, 2024. How many different contributors worked on these PRs?</question>
      <answer>7</answer>
   </qa_pair>
   <qa_pair>
      <question>Find the repository with the most stars that was created before 2023. What is the repository name?</question>
      <answer>data-pipeline</answer>
   </qa_pair>
</evaluation>
```

## Evaluation Examples

### Good Questions

**Example 1: Multi-hop question requiring deep exploration (GitHub MCP)**
```xml
<qa_pair>
   <question>Find the repository that was archived in Q3 2023 and had previously been the most forked project in the organization. What was the primary programming language used in that repository?</question>
   <answer>Python</answer>
</qa_pair>
```

This question is good because:
- Requires multiple searches to find archived repositories
- Needs to identify which had the most forks before archival
- Requires examining repository details for the language
- Answer is a simple, verifiable value
- Based on historical (closed) data that won't change

**Example 2: Requires understanding context without keyword matching (Project Management MCP)**
```xml
<qa_pair>
   <question>Locate the initiative focused on improving customer onboarding that was completed in late 2023. The project lead created a retrospective document after completion. What was the lead's role title at that time?</question>
   <answer>Product Manager</answer>
</qa_pair>
```

This question is good because:
- Doesn't use specific project name ("initiative focused on improving customer onboarding")
- Requires finding completed projects from specific timeframe
- Needs to identify the project lead and their role
- Requires understanding context from retrospective documents
- Answer is human-readable and stable
- Based on completed work (won't change)

**Example 3: Complex aggregation requiring multiple steps (Issue Tracker MCP)**
```xml
<qa_pair>
   <question>Among all bugs reported in January 2024 that were marked as critical priority, which assignee resolved the highest percentage of their assigned bugs within 48 hours? Provide the assignee's username.</question>
   <answer>alex_eng</answer>
</qa_pair>
```

This question is good because:
- Requires filtering bugs by date, priority, and status
- Needs to group by assignee and calculate resolution rates
- Requires understanding timestamps to determine 48-hour windows
- Tests pagination (potentially many bugs to process)
- Answer is a single username
- Based on historical data from specific time period

**Example 4: Requires synthesis across multiple data types (CRM MCP)**
```xml
<qa_pair>
   <question>Find the account that upgraded from the Starter to Enterprise plan in Q4 2023 and had the highest annual contract value. What industry does this account operate in?</question>
   <answer>Healthcare</answer>
</qa_pair>
```

This question is good because:
- Requires understanding subscription tier changes
- Needs to identify upgrade events in specific timeframe
- Requires comparing contract values
- Must access account industry information
- Answer is simple and verifiable
- Based on completed historical transactions

### Poor Questions

**Example 1: Answer changes over time**
```xml
<qa_pair>
   <question>How many open issues are currently assigned to the engineering team?</question>
   <answer>47</answer>
</qa_pair>
```

This question is poor because:
- The answer will change as issues are created, closed, or reassigned
- Not based on stable/stationary data
- Relies on "current state" which is dynamic

**Example 2: Too easy with keyword search**
```xml
<qa_pair>
   <question>Find the pull request with title "Add authentication feature" and tell me who created it.</question>
   <answer>developer123</answer>
</qa_pair>
```

This question is poor because:
- Can be solved with a straightforward keyword search for exact title
- Doesn't require deep exploration or understanding
- No synthesis or analysis needed

**Example 3: Ambiguous answer format**
```xml
<qa_pair>
   <question>List all the repositories that have Python as their primary language.</question>
   <answer>repo1, repo2, repo3, data-pipeline, ml-tools</answer>
</qa_pair>
```

This question is poor because:
- Answer is a list that could be returned in any order
- Difficult to verify with direct string comparison
- LLM might format differently (JSON array, comma-separated, newline-separated)
- Better to ask for a specific aggregate (count) or superlative (most stars)

## Verification Process

After creating evaluations:

1. **Examine the XML file** to understand the schema
2. **Load each task instruction** and in parallel using the MCP server and tools, identify the correct answer by attempting to solve the task YOURSELF
3. **Flag any operations** that require WRITE or DESTRUCTIVE operations
4. **Accumulate all CORRECT answers** and replace any incorrect answers in the document
5. **Remove any `<qa_pair>`** that require WRITE or DESTRUCTIVE operations

Remember to parallelize solving tasks to avoid running out of context, then accumulate all answers and make changes to the file at the end.

## Tips for Creating Quality Evaluations

1. **Think Hard and Plan Ahead** before generating tasks
2. **Parallelize Where Opportunity Arises** to speed up the process and manage context
3. **Focus on Realistic Use Cases** that humans would actually want to accomplish
4. **Create Challenging Questions** that test the limits of the MCP server's capabilities
5. **Ensure Stability** by using historical data and closed concepts
6. **Verify Answers** by solving the questions yourself using the MCP server tools
7. **Iterate and Refine** based on what you learn during the process

# Running Evaluations

After creating your evaluation file, you can use the provided evaluation harness to test your MCP server.

## Setup

1. **Install Dependencies**

   ```bash
   pip install -r scripts/requirements.txt
   ```

   Or install manually:
   ```bash
   pip install anthropic mcp
   ```

2. **Set API Key**

   ```bash
   export ANTHROPIC_API_KEY=your_api_key_here
   ```

## Evaluation File Format

Evaluation files use XML format with `<qa_pair>` elements:

```xml
<evaluation>
   <qa_pair>
      <question>Find the project created in Q2 2024 with the highest number of completed tasks. What is the project name?</question>
      <answer>Website Redesign</answer>
   </qa_pair>
   <qa_pair>
      <question>Search for issues labeled as "bug" that were closed in March 2024. Which user closed the most issues? Provide their username.</question>
      <answer>sarah_dev</answer>
   </qa_pair>
</evaluation>
```

## Running Evaluations

The evaluation script (`scripts/evaluation.py`) supports three transport types:

**Important:**
- **stdio transport**: The evaluation script automatically launches and manages the MCP server process for you. Do not run the server manually.
- **sse/http transports**: You must start the MCP server separately before running the evaluation. The script connects to the already-running server at the specified URL.

### 1. Local STDIO Server

For locally-run MCP servers (script launches the server automatically):

```bash
python scripts/evaluation.py \
  -t stdio \
  -c python \
  -a my_mcp_server.py \
  evaluation.xml
```

With environment variables:
```bash
python scripts/evaluation.py \
  -t stdio \
  -c python \
  -a my_mcp_server.py \
  -e API_KEY=abc123 \
  -e DEBUG=true \
  evaluation.xml
```

### 2. Server-Sent Events (SSE)

For SSE-based MCP servers (you must start the server first):

```bash
python scripts/evaluation.py \
  -t sse \
  -u https://example.com/mcp \
  -H "Authorization: Bearer token123" \
  -H "X-Custom-Header: value" \
  evaluation.xml
```

### 3. HTTP (Streamable HTTP)

For HTTP-based MCP servers (you must start the server first):

```bash
python scripts/evaluation.py \
  -t http \
  -u https://example.com/mcp \
  -H "Authorization: Bearer token123" \
  evaluation.xml
```

## Command-Line Options

```
usage: evaluation.py [-h] [-t {stdio,sse,http}] [-m MODEL] [-c COMMAND]
                     [-a ARGS [ARGS ...]] [-e ENV [ENV ...]] [-u URL]
                     [-H HEADERS [HEADERS ...]] [-o OUTPUT]
                     eval_file

positional arguments:
  eval_file             Path to evaluation XML file

optional arguments:
  -h, --help            Show help message
  -t, --transport       Transport type: stdio, sse, or http (default: stdio)
  -m, --model           Claude model to use (default: claude-3-7-sonnet-20250219)
  -o, --output          Output file for report (default: print to stdout)

stdio options:
  -c, --command         Command to run MCP server (e.g., python, node)
  -a, --args            Arguments for the command (e.g., server.py)
  -e, --env             Environment variables in KEY=VALUE format

sse/http options:
  -u, --url             MCP server URL
  -H, --header          HTTP headers in 'Key: Value' format
```

## Output

The evaluation script generates a detailed report including:

- **Summary Statistics**:
  - Accuracy (correct/total)
  - Average task duration
  - Average tool calls per task
  - Total tool calls

- **Per-Task Results**:
  - Prompt and expected response
  - Actual response from the agent
  - Whether the answer was correct (✅/❌)
  - Duration and tool call details
  - Agent's summary of its approach
  - Agent's feedback on the tools

### Save Report to File

```bash
python scripts/evaluation.py \
  -t stdio \
  -c python \
  -a my_server.py \
  -o evaluation_report.md \
  evaluation.xml
```

## Complete Example Workflow

Here's a complete example of creating and running an evaluation:

1. **Create your evaluation file** (`my_evaluation.xml`):

```xml
<evaluation>
   <qa_pair>
      <question>Find the user who created the most issues in January 2024. What is their username?</question>
      <answer>alice_developer</answer>
   </qa_pair>
   <qa_pair>
      <question>Among all pull requests merged in Q1 2024, which repository had the highest number? Provide the repository name.</question>
      <answer>backend-api</answer>
   </qa_pair>
   <qa_pair>
      <question>Find the project that was completed in December 2023 and had the longest duration from start to finish. How many days did it take?</question>
      <answer>127</answer>
   </qa_pair>
</evaluation>
```

2. **Install dependencies**:

```bash
pip install -r scripts/requirements.txt
export ANTHROPIC_API_KEY=your_api_key
```

3. **Run evaluation**:

```bash
python scripts/evaluation.py \
  -t stdio \
  -c python \
  -a github_mcp_server.py \
  -e GITHUB_TOKEN=ghp_xxx \
  -o github_eval_report.md \
  my_evaluation.xml
```

4. **Review the report** in `github_eval_report.md` to:
   - See which questions passed/failed
   - Read the agent's feedback on your tools
   - Identify areas for improvement
   - Iterate on your MCP server design

## Troubleshooting

### Connection Errors

If you get connection errors:
- **STDIO**: Verify the command and arguments are correct
- **SSE/HTTP**: Check the URL is accessible and headers are correct
- Ensure any required API keys are set in environment variables or headers

### Low Accuracy

If many evaluations fail:
- Review the agent's feedback for each task
- Check if tool descriptions are clear and comprehensive
- Verify input parameters are well-documented
- Consider whether tools return too much or too little data
- Ensure error messages are actionable

### Timeout Issues

If tasks are timing out:
- Use a more capable model (e.g., `claude-3-7-sonnet-20250219`)
- Check if tools are returning too much data
- Verify pagination is working correctly
- Consider simplifying complex questions

# Node/TypeScript MCP Server Implementation Guide

## Overview

This document provides Node/TypeScript-specific best practices and examples for implementing MCP servers using the MCP TypeScript SDK. It covers project structure, server setup, tool registration patterns, input validation with Zod, error handling, and complete working examples.

---

## Quick Reference

### Key Imports
```typescript
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StreamableHTTPServerTransport } from "@modelcontextprotocol/sdk/server/streamableHttp.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import express from "express";
import { z } from "zod";
```

### Server Initialization
```typescript
const server = new McpServer({
  name: "service-mcp-server",
  version: "1.0.0"
});
```

### Tool Registration Pattern
```typescript
server.registerTool(
  "tool_name",
  {
    title: "Tool Display Name",
    description: "What the tool does",
    inputSchema: { param: z.string() },
    outputSchema: { result: z.string() }
  },
  async ({ param }) => {
    const output = { result: `Processed: param` };
    return {
      content: [{ type: "text", text: JSON.stringify(output) }],
      structuredContent: output // Modern pattern for structured data
    };
  }
);
```

---

## MCP TypeScript SDK

The official MCP TypeScript SDK provides:
- `McpServer` class for server initialization
- `registerTool` method for tool registration
- Zod schema integration for runtime input validation
- Type-safe tool handler implementations

**IMPORTANT - Use Modern APIs Only:**
- **DO use**: `server.registerTool()`, `server.registerResource()`, `server.registerPrompt()`
- **DO NOT use**: Old deprecated APIs such as `server.tool()`, `server.setRequestHandler(ListToolsRequestSchema, ...)`, or manual handler registration
- The `register*` methods provide better type safety, automatic schema handling, and are the recommended approach

See the MCP SDK documentation in the references for complete details.

## Server Naming Convention

Node/TypeScript MCP servers must follow this naming pattern:
- **Format**: `{service}-mcp-server` (lowercase with hyphens)
- **Examples**: `github-mcp-server`, `jira-mcp-server`, `stripe-mcp-server`

The name should be:
- General (not tied to specific features)
- Descriptive of the service/API being integrated
- Easy to infer from the task description
- Without version numbers or dates

## Project Structure

Create the following structure for Node/TypeScript MCP servers:

```
{service}-mcp-server/
├── package.json
├── tsconfig.json
├── README.md
├── src/
│   ├── index.ts          # Main entry point with McpServer initialization
│   ├── types.ts          # TypeScript type definitions and interfaces
│   ├── tools/            # Tool implementations (one file per domain)
│   ├── services/         # API clients and shared utilities
│   ├── schemas/          # Zod validation schemas
│   └── constants.ts      # Shared constants (API_URL, CHARACTER_LIMIT, etc.)
└── dist/                 # Built JavaScript files (entry point: dist/index.js)
```

## Tool Implementation

### Tool Naming

Use snake_case for tool names (e.g., "search_users", "create_project", "get_channel_info") with clear, action-oriented names.

**Avoid Naming Conflicts**: Include the service context to prevent overlaps:
- Use "slack_send_message" instead of just "send_message"
- Use "github_create_issue" instead of just "create_issue"
- Use "asana_list_tasks" instead of just "list_tasks"

### Tool Structure

Tools are registered using the `registerTool` method with the following requirements:
- Use Zod schemas for runtime input validation and type safety
- The `description` field must be explicitly provided - JSDoc comments are NOT automatically extracted
- Explicitly provide `title`, `description`, `inputSchema`, and `annotations`
- The `inputSchema` must be a Zod schema object (not a JSON schema)
- Type all parameters and return values explicitly

```typescript
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { z } from "zod";

const server = new McpServer({
  name: "example-mcp",
  version: "1.0.0"
});

// Zod schema for input validation
const UserSearchInputSchema = z.object({
  query: z.string()
    .min(2, "Query must be at least 2 characters")
    .max(200, "Query must not exceed 200 characters")
    .describe("Search string to match against names/emails"),
  limit: z.number()
    .int()
    .min(1)
    .max(100)
    .default(20)
    .describe("Maximum results to return"),
  offset: z.number()
    .int()
    .min(0)
    .default(0)
    .describe("Number of results to skip for pagination"),
  response_format: z.nativeEnum(ResponseFormat)
    .default(ResponseFormat.MARKDOWN)
    .describe("Output format: 'markdown' for human-readable or 'json' for machine-readable")
}).strict();

// Type definition from Zod schema
type UserSearchInput = z.infer<typeof UserSearchInputSchema>;

server.registerTool(
  "example_search_users",
  {
    title: "Search Example Users",
    description: `Search for users in the Example system by name, email, or team.

This tool searches across all user profiles in the Example platform, supporting partial matches and various search filters. It does NOT create or modify users, only searches existing ones.

Args:
  - query (string): Search string to match against names/emails
  - limit (number): Maximum results to return, between 1-100 (default: 20)
  - offset (number): Number of results to skip for pagination (default: 0)
  - response_format ('markdown' | 'json'): Output format (default: 'markdown')

Returns:
  For JSON format: Structured data with schema:
  {
    "total": number,           // Total number of matches found
    "count": number,           // Number of results in this response
    "offset": number,          // Current pagination offset
    "users": [
      {
        "id": string,          // User ID (e.g., "U123456789")
        "name": string,        // Full name (e.g., "John Doe")
        "email": string,       // Email address
        "team": string,        // Team name (optional)
        "active": boolean      // Whether user is active
      }
    ],
    "has_more": boolean,       // Whether more results are available
    "next_offset": number      // Offset for next page (if has_more is true)
  }

Examples:
  - Use when: "Find all marketing team members" -> params with query="team:marketing"
  - Use when: "Search for John's account" -> params with query="john"
  - Don't use when: You need to create a user (use example_create_user instead)

Error Handling:
  - Returns "Error: Rate limit exceeded" if too many requests (429 status)
  - Returns "No users found matching '<query>'" if search returns empty`,
    inputSchema: UserSearchInputSchema,
    annotations: {
      readOnlyHint: true,
      destructiveHint: false,
      idempotentHint: true,
      openWorldHint: true
    }
  },
  async (params: UserSearchInput) => {
    try {
      // Input validation is handled by Zod schema
      // Make API request using validated parameters
      const data = await makeApiRequest<any>(
        "users/search",
        "GET",
        undefined,
        {
          q: params.query,
          limit: params.limit,
          offset: params.offset
        }
      );

      const users = data.users || [];
      const total = data.total || 0;

      if (!users.length) {
        return {
          content: [{
            type: "text",
            text: `No users found matching 'params.query'`
          }]
        };
      }

      // Prepare structured output
      const output = {
        total,
        count: users.length,
        offset: params.offset,
        users: users.map((user: any) => ({
          id: user.id,
          name: user.name,
          email: user.email,
          ...(user.team ? { team: user.team } : {}),
          active: user.active ?? true
        })),
        has_more: total > params.offset + users.length,
        ...(total > params.offset + users.length ? {
          next_offset: params.offset + users.length
        } : {})
      };

      // Format text representation based on requested format
      let textContent: string;
      if (params.response_format === ResponseFormat.MARKDOWN) {
        const lines = [`# User Search Results: 'params.query'`, "",
          `Found total users (showing users.length)`, ""];
        for (const user of users) {
          lines.push(`## user.name (user.id)`);
          lines.push(`- **Email**: user.email`);
          if (user.team) lines.push(`- **Team**: user.team`);
          lines.push("");
        }
        textContent = lines.join("\n");
      } else {
        textContent = JSON.stringify(output, null, 2);
      }

      return {
        content: [{ type: "text", text: textContent }],
        structuredContent: output // Modern pattern for structured data
      };
    } catch (error) {
      return {
        content: [{
          type: "text",
          text: handleApiError(error)
        }]
      };
    }
  }
);
```

## Zod Schemas for Input Validation

Zod provides runtime type validation:

```typescript
import { z } from "zod";

// Basic schema with validation
const CreateUserSchema = z.object({
  name: z.string()
    .min(1, "Name is required")
    .max(100, "Name must not exceed 100 characters"),
  email: z.string()
    .email("Invalid email format"),
  age: z.number()
    .int("Age must be a whole number")
    .min(0, "Age cannot be negative")
    .max(150, "Age cannot be greater than 150")
}).strict();  // Use .strict() to forbid extra fields

// Enums
enum ResponseFormat {
  MARKDOWN = "markdown",
  JSON = "json"
}

const SearchSchema = z.object({
  response_format: z.nativeEnum(ResponseFormat)
    .default(ResponseFormat.MARKDOWN)
    .describe("Output format")
});

// Optional fields with defaults
const PaginationSchema = z.object({
  limit: z.number()
    .int()
    .min(1)
    .max(100)
    .default(20)
    .describe("Maximum results to return"),
  offset: z.number()
    .int()
    .min(0)
    .default(0)
    .describe("Number of results to skip")
});
```

## Response Format Options

Support multiple output formats for flexibility:

```typescript
enum ResponseFormat {
  MARKDOWN = "markdown",
  JSON = "json"
}

const inputSchema = z.object({
  query: z.string(),
  response_format: z.nativeEnum(ResponseFormat)
    .default(ResponseFormat.MARKDOWN)
    .describe("Output format: 'markdown' for human-readable or 'json' for machine-readable")
});
```

**Markdown format**:
- Use headers, lists, and formatting for clarity
- Convert timestamps to human-readable format
- Show display names with IDs in parentheses
- Omit verbose metadata
- Group related information logically

**JSON format**:
- Return complete, structured data suitable for programmatic processing
- Include all available fields and metadata
- Use consistent field names and types

## Pagination Implementation

For tools that list resources:

```typescript
const ListSchema = z.object({
  limit: z.number().int().min(1).max(100).default(20),
  offset: z.number().int().min(0).default(0)
});

async function listItems(params: z.infer<typeof ListSchema>) {
  const data = await apiRequest(params.limit, params.offset);

  const response = {
    total: data.total,
    count: data.items.length,
    offset: params.offset,
    items: data.items,
    has_more: data.total > params.offset + data.items.length,
    next_offset: data.total > params.offset + data.items.length
      ? params.offset + data.items.length
      : undefined
  };

  return JSON.stringify(response, null, 2);
}
```

## Character Limits and Truncation

Add a CHARACTER_LIMIT constant to prevent overwhelming responses:

```typescript
// At module level in constants.ts
export const CHARACTER_LIMIT = 25000;  // Maximum response size in characters

async function searchTool(params: SearchInput) {
  let result = generateResponse(data);

  // Check character limit and truncate if needed
  if (result.length > CHARACTER_LIMIT) {
    const truncatedData = data.slice(0, Math.max(1, data.length / 2));
    response.data = truncatedData;
    response.truncated = true;
    response.truncation_message =
      `Response truncated from data.length to truncatedData.length items. ` +
      `Use 'offset' parameter or add filters to see more results.`;
    result = JSON.stringify(response, null, 2);
  }

  return result;
}
```

## Error Handling

Provide clear, actionable error messages:

```typescript
import axios, { AxiosError } from "axios";

function handleApiError(error: unknown): string {
  if (error instanceof AxiosError) {
    if (error.response) {
      switch (error.response.status) {
        case 404:
          return "Error: Resource not found. Please check the ID is correct.";
        case 403:
          return "Error: Permission denied. You don't have access to this resource.";
        case 429:
          return "Error: Rate limit exceeded. Please wait before making more requests.";
        default:
          return `Error: API request failed with status error.response.status`;
      }
    } else if (error.code === "ECONNABORTED") {
      return "Error: Request timed out. Please try again.";
    }
  }
  return `Error: Unexpected error occurred: String(error)`;
}
```

## Shared Utilities

Extract common functionality into reusable functions:

```typescript
// Shared API request function
async function makeApiRequest<T>(
  endpoint: string,
  method: "GET" | "POST" | "PUT" | "DELETE" = "GET",
  data?: any,
  params?: any
): Promise<T> {
  try {
    const response = await axios({
      method,
      url: `API_BASE_URL/endpoint`,
      data,
      params,
      timeout: 30000,
      headers: {
        "Content-Type": "application/json",
        "Accept": "application/json"
      }
    });
    return response.data;
  } catch (error) {
    throw error;
  }
}
```

## Async/Await Best Practices

Always use async/await for network requests and I/O operations:

```typescript
// Good: Async network request
async function fetchData(resourceId: string): Promise<ResourceData> {
  const response = await axios.get(`API_URL/resource/resourceId`);
  return response.data;
}

// Bad: Promise chains
function fetchData(resourceId: string): Promise<ResourceData> {
  return axios.get(`API_URL/resource/resourceId`)
    .then(response => response.data);  // Harder to read and maintain
}
```

## TypeScript Best Practices

1. **Use Strict TypeScript**: Enable strict mode in tsconfig.json
2. **Define Interfaces**: Create clear interface definitions for all data structures
3. **Avoid `any`**: Use proper types or `unknown` instead of `any`
4. **Zod for Runtime Validation**: Use Zod schemas to validate external data
5. **Type Guards**: Create type guard functions for complex type checking
6. **Error Handling**: Always use try-catch with proper error type checking
7. **Null Safety**: Use optional chaining (`?.`) and nullish coalescing (`??`)

```typescript
// Good: Type-safe with Zod and interfaces
interface UserResponse {
  id: string;
  name: string;
  email: string;
  team?: string;
  active: boolean;
}

const UserSchema = z.object({
  id: z.string(),
  name: z.string(),
  email: z.string().email(),
  team: z.string().optional(),
  active: z.boolean()
});

type User = z.infer<typeof UserSchema>;

async function getUser(id: string): Promise<User> {
  const data = await apiCall(`/users/id`);
  return UserSchema.parse(data);  // Runtime validation
}

// Bad: Using any
async function getUser(id: string): Promise<any> {
  return await apiCall(`/users/id`);  // No type safety
}
```

## Advanced MCP Features

### Resource Registration

Expose data as resources for efficient, URI-based access:

```typescript
import { ResourceTemplate } from "@modelcontextprotocol/sdk/types.js";

// Register a resource with URI template
server.registerResource(
  {
    uri: "file://documents/{name}",
    name: "Document Resource",
    description: "Access documents by name",
    mimeType: "text/plain"
  },
  async (uri: string) => {
    // Extract parameter from URI
    const match = uri.match(/^file:\/\/documents\/(.+)$/);
    if (!match) {
      throw new Error("Invalid URI format");
    }

    const documentName = match[1];
    const content = await loadDocument(documentName);

    return {
      contents: [{
        uri,
        mimeType: "text/plain",
        text: content
      }]
    };
  }
);

// List available resources dynamically
server.registerResourceList(async () => {
  const documents = await getAvailableDocuments();
  return {
    resources: documents.map(doc => ({
      uri: `file://documents/doc.name`,
      name: doc.name,
      mimeType: "text/plain",
      description: doc.description
    }))
  };
});
```

**When to use Resources vs Tools:**
- **Resources**: For data access with simple URI-based parameters
- **Tools**: For complex operations requiring validation and business logic
- **Resources**: When data is relatively static or template-based
- **Tools**: When operations have side effects or complex workflows

### Transport Options

The TypeScript SDK supports two main transport mechanisms:

#### Streamable HTTP (Recommended for Remote Servers)

```typescript
import { StreamableHTTPServerTransport } from "@modelcontextprotocol/sdk/server/streamableHttp.js";
import express from "express";

const app = express();
app.use(express.json());

app.post('/mcp', async (req, res) => {
  // Create new transport for each request (stateless, prevents request ID collisions)
  const transport = new StreamableHTTPServerTransport({
    sessionIdGenerator: undefined,
    enableJsonResponse: true
  });

  res.on('close', () => transport.close());

  await server.connect(transport);
  await transport.handleRequest(req, res, req.body);
});

app.listen(3000);
```

#### stdio (For Local Integrations)

```typescript
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";

const transport = new StdioServerTransport();
await server.connect(transport);
```

**Transport selection:**
- **Streamable HTTP**: Web services, remote access, multiple clients
- **stdio**: Command-line tools, local development, subprocess integration

### Notification Support

Notify clients when server state changes:

```typescript
// Notify when tools list changes
server.notification({
  method: "notifications/tools/list_changed"
});

// Notify when resources change
server.notification({
  method: "notifications/resources/list_changed"
});
```

Use notifications sparingly - only when server capabilities genuinely change.

## Code Best Practices

### Code Composability and Reusability

Your implementation MUST prioritize composability and code reuse:

1. **Extract Common Functionality**:
   - Create reusable helper functions for operations used across multiple tools
   - Build shared API clients for HTTP requests instead of duplicating code
   - Centralize error handling logic in utility functions
   - Extract business logic into dedicated functions that can be composed
   - Extract shared markdown or JSON field selection & formatting functionality

2. **Avoid Duplication**:
   - NEVER copy-paste similar code between tools
   - If you find yourself writing similar logic twice, extract it into a function
   - Common operations like pagination, filtering, field selection, and formatting should be shared
   - Authentication/authorization logic should be centralized

## Building and Running

Always build your TypeScript code before running:

```bash
# Build the project
npm run build

# Run the server
npm start

# Development with auto-reload
npm run dev
```

Always ensure `npm run build` completes successfully before considering the implementation complete.

## Quality Checklist

# Python MCP Server Implementation Guide

## Overview

This document provides Python-specific best practices and examples for implementing MCP servers using the MCP Python SDK. It covers server setup, tool registration patterns, input validation with Pydantic, error handling, and complete working examples.

---

## Quick Reference

### Key Imports
```python
from mcp.server.fastmcp import FastMCP
from pydantic import BaseModel, Field, field_validator, ConfigDict
from typing import Optional, List, Dict, Any
from enum import Enum
import httpx
```

### Server Initialization
```python
mcp = FastMCP("service_mcp")
```

### Tool Registration Pattern
```python
@mcp.tool(name="tool_name", annotations={...})
async def tool_function(params: InputModel) -> str:
    # Implementation
    pass
```

---

## MCP Python SDK and FastMCP

The official MCP Python SDK provides FastMCP, a high-level framework for building MCP servers. It provides:
- Automatic description and inputSchema generation from function signatures and docstrings
- Pydantic model integration for input validation
- Decorator-based tool registration with `@mcp.tool`

**For complete SDK documentation, use WebFetch to load:**
`https://raw.githubusercontent.com/modelcontextprotocol/python-sdk/main/README.md`

## Server Naming Convention

Python MCP servers must follow this naming pattern:
- **Format**: `{service}_mcp` (lowercase with underscores)
- **Examples**: `github_mcp`, `jira_mcp`, `stripe_mcp`

The name should be:
- General (not tied to specific features)
- Descriptive of the service/API being integrated
- Easy to infer from the task description
- Without version numbers or dates

## Tool Implementation

### Tool Naming

Use snake_case for tool names (e.g., "search_users", "create_project", "get_channel_info") with clear, action-oriented names.

**Avoid Naming Conflicts**: Include the service context to prevent overlaps:
- Use "slack_send_message" instead of just "send_message"
- Use "github_create_issue" instead of just "create_issue"
- Use "asana_list_tasks" instead of just "list_tasks"

### Tool Structure with FastMCP

Tools are defined using the `@mcp.tool` decorator with Pydantic models for input validation:

```python
from pydantic import BaseModel, Field, ConfigDict
from mcp.server.fastmcp import FastMCP

# Initialize the MCP server
mcp = FastMCP("example_mcp")

# Define Pydantic model for input validation
class ServiceToolInput(BaseModel):
    '''Input model for service tool operation.'''
    model_config = ConfigDict(
        str_strip_whitespace=True,  # Auto-strip whitespace from strings
        validate_assignment=True,    # Validate on assignment
        extra='forbid'              # Forbid extra fields
    )

    param1: str = Field(..., description="First parameter description (e.g., 'user123', 'project-abc')", min_length=1, max_length=100)
    param2: Optional[int] = Field(default=None, description="Optional integer parameter with constraints", ge=0, le=1000)
    tags: Optional[List[str]] = Field(default_factory=list, description="List of tags to apply", max_items=10)

@mcp.tool(
    name="service_tool_name",
    annotations={
        "title": "Human-Readable Tool Title",
        "readOnlyHint": True,     # Tool does not modify environment
        "destructiveHint": False,  # Tool does not perform destructive operations
        "idempotentHint": True,    # Repeated calls have no additional effect
        "openWorldHint": False     # Tool does not interact with external entities
    }
)
async def service_tool_name(params: ServiceToolInput) -> str:
    '''Tool description automatically becomes the 'description' field.

    This tool performs a specific operation on the service. It validates all inputs
    using the ServiceToolInput Pydantic model before processing.

    Args:
        params (ServiceToolInput): Validated input parameters containing:
            - param1 (str): First parameter description
            - param2 (Optional[int]): Optional parameter with default
            - tags (Optional[List[str]]): List of tags

    Returns:
        str: JSON-formatted response containing operation results
    '''
    # Implementation here
    pass
```

## Pydantic v2 Key Features

- Use `model_config` instead of nested `Config` class
- Use `field_validator` instead of deprecated `validator`
- Use `model_dump()` instead of deprecated `dict()`
- Validators require `@classmethod` decorator
- Type hints are required for validator methods

```python
from pydantic import BaseModel, Field, field_validator, ConfigDict

class CreateUserInput(BaseModel):
    model_config = ConfigDict(
        str_strip_whitespace=True,
        validate_assignment=True
    )

    name: str = Field(..., description="User's full name", min_length=1, max_length=100)
    email: str = Field(..., description="User's email address", pattern=r'^[\w\.-]+@[\w\.-]+\.\w+$')
    age: int = Field(..., description="User's age", ge=0, le=150)

    @field_validator('email')
    @classmethod
    def validate_email(cls, v: str) -> str:
        if not v.strip():
            raise ValueError("Email cannot be empty")
        return v.lower()
```

## Response Format Options

Support multiple output formats for flexibility:

```python
from enum import Enum

class ResponseFormat(str, Enum):
    '''Output format for tool responses.'''
    MARKDOWN = "markdown"
    JSON = "json"

class UserSearchInput(BaseModel):
    query: str = Field(..., description="Search query")
    response_format: ResponseFormat = Field(
        default=ResponseFormat.MARKDOWN,
        description="Output format: 'markdown' for human-readable or 'json' for machine-readable"
    )
```

**Markdown format**:
- Use headers, lists, and formatting for clarity
- Convert timestamps to human-readable format (e.g., "2024-01-15 10:30:00 UTC" instead of epoch)
- Show display names with IDs in parentheses (e.g., "@john.doe (U123456)")
- Omit verbose metadata (e.g., show only one profile image URL, not all sizes)
- Group related information logically

**JSON format**:
- Return complete, structured data suitable for programmatic processing
- Include all available fields and metadata
- Use consistent field names and types

## Pagination Implementation

For tools that list resources:

```python
class ListInput(BaseModel):
    limit: Optional[int] = Field(default=20, description="Maximum results to return", ge=1, le=100)
    offset: Optional[int] = Field(default=0, description="Number of results to skip for pagination", ge=0)

async def list_items(params: ListInput) -> str:
    # Make API request with pagination
    data = await api_request(limit=params.limit, offset=params.offset)

    # Return pagination info
    response = {
        "total": data["total"],
        "count": len(data["items"]),
        "offset": params.offset,
        "items": data["items"],
        "has_more": data["total"] > params.offset + len(data["items"]),
        "next_offset": params.offset + len(data["items"]) if data["total"] > params.offset + len(data["items"]) else None
    }
    return json.dumps(response, indent=2)
```

## Error Handling

Provide clear, actionable error messages:

```python
def _handle_api_error(e: Exception) -> str:
    '''Consistent error formatting across all tools.'''
    if isinstance(e, httpx.HTTPStatusError):
        if e.response.status_code == 404:
            return "Error: Resource not found. Please check the ID is correct."
        elif e.response.status_code == 403:
            return "Error: Permission denied. You don't have access to this resource."
        elif e.response.status_code == 429:
            return "Error: Rate limit exceeded. Please wait before making more requests."
        return f"Error: API request failed with status {e.response.status_code}"
    elif isinstance(e, httpx.TimeoutException):
        return "Error: Request timed out. Please try again."
    return f"Error: Unexpected error occurred: {type(e).__name__}"
```

## Shared Utilities

Extract common functionality into reusable functions:

```python
# Shared API request function
async def _make_api_request(endpoint: str, method: str = "GET", **kwargs) -> dict:
    '''Reusable function for all API calls.'''
    async with httpx.AsyncClient() as client:
        response = await client.request(
            method,
            f"{API_BASE_URL}/{endpoint}",
            timeout=30.0,
            **kwargs
        )
        response.raise_for_status()
        return response.json()
```

## Async/Await Best Practices

Always use async/await for network requests and I/O operations:

```python
# Good: Async network request
async def fetch_data(resource_id: str) -> dict:
    async with httpx.AsyncClient() as client:
        response = await client.get(f"{API_URL}/resource/{resource_id}")
        response.raise_for_status()
        return response.json()

# Bad: Synchronous request
def fetch_data(resource_id: str) -> dict:
    response = requests.get(f"{API_URL}/resource/{resource_id}")  # Blocks
    return response.json()
```

## Type Hints

Use type hints throughout:

```python
from typing import Optional, List, Dict, Any

async def get_user(user_id: str) -> Dict[str, Any]:
    data = await fetch_user(user_id)
    return {"id": data["id"], "name": data["name"]}
```

## Tool Docstrings

Every tool must have comprehensive docstrings with explicit type information:

```python
async def search_users(params: UserSearchInput) -> str:
    '''
    Search for users in the Example system by name, email, or team.

    This tool searches across all user profiles in the Example platform,
    supporting partial matches and various search filters. It does NOT
    create or modify users, only searches existing ones.

    Args:
        params (UserSearchInput): Validated input parameters containing:
            - query (str): Search string to match against names/emails (e.g., "john", "@example.com", "team:marketing")
            - limit (Optional[int]): Maximum results to return, between 1-100 (default: 20)
            - offset (Optional[int]): Number of results to skip for pagination (default: 0)

    Returns:
        str: JSON-formatted string containing search results with the following schema:

        Success response:
        {
            "total": int,           # Total number of matches found
            "count": int,           # Number of results in this response
            "offset": int,          # Current pagination offset
            "users": [
                {
                    "id": str,      # User ID (e.g., "U123456789")
                    "name": str,    # Full name (e.g., "John Doe")
                    "email": str,   # Email address (e.g., "john@example.com")
                    "team": str     # Team name (e.g., "Marketing") - optional
                }
            ]
        }

        Error response:
        "Error: <error message>" or "No users found matching '<query>'"

    Examples:
        - Use when: "Find all marketing team members" -> params with query="team:marketing"
        - Use when: "Search for John's account" -> params with query="john"
        - Don't use when: You need to create a user (use example_create_user instead)
        - Don't use when: You have a user ID and need full details (use example_get_user instead)

    Error Handling:
        - Input validation errors are handled by Pydantic model
        - Returns "Error: Rate limit exceeded" if too many requests (429 status)
        - Returns "Error: Invalid API authentication" if API key is invalid (401 status)
        - Returns formatted list of results or "No users found matching 'query'"
    '''
```

## Advanced FastMCP Features

### Context Parameter Injection

FastMCP can automatically inject a `Context` parameter into tools for advanced capabilities like logging, progress reporting, resource reading, and user interaction:

```python
from mcp.server.fastmcp import FastMCP, Context

mcp = FastMCP("example_mcp")

@mcp.tool()
async def advanced_search(query: str, ctx: Context) -> str:
    '''Advanced tool with context access for logging and progress.'''

    # Report progress for long operations
    await ctx.report_progress(0.25, "Starting search...")

    # Log information for debugging
    await ctx.log_info("Processing query", {"query": query, "timestamp": datetime.now()})

    # Perform search
    results = await search_api(query)
    await ctx.report_progress(0.75, "Formatting results...")

    # Access server configuration
    server_name = ctx.fastmcp.name

    return format_results(results)

@mcp.tool()
async def interactive_tool(resource_id: str, ctx: Context) -> str:
    '''Tool that can request additional input from users.'''

    # Request sensitive information when needed
    api_key = await ctx.elicit(
        prompt="Please provide your API key:",
        input_type="password"
    )

    # Use the provided key
    return await api_call(resource_id, api_key)
```

**Context capabilities:**
- `ctx.report_progress(progress, message)` - Report progress for long operations
- `ctx.log_info(message, data)` / `ctx.log_error()` / `ctx.log_debug()` - Logging
- `ctx.elicit(prompt, input_type)` - Request input from users
- `ctx.fastmcp.name` - Access server configuration
- `ctx.read_resource(uri)` - Read MCP resources

### Resource Registration

Expose data as resources for efficient, template-based access:

```python
@mcp.resource("file://documents/{name}")
async def get_document(name: str) -> str:
    '''Expose documents as MCP resources.

    Resources are useful for static or semi-static data that doesn't
    require complex parameters. They use URI templates for flexible access.
    '''
    document_path = f"./docs/{name}"
    with open(document_path, "r") as f:
        return f.read()

@mcp.resource("config://settings/{key}")
async def get_setting(key: str, ctx: Context) -> str:
    '''Expose configuration as resources with context.'''
    settings = await load_settings()
    return json.dumps(settings.get(key, {}))
```

**When to use Resources vs Tools:**
- **Resources**: For data access with simple parameters (URI templates)
- **Tools**: For complex operations with validation and business logic

### Structured Output Types

FastMCP supports multiple return types beyond strings:

```python
from typing import TypedDict
from dataclasses import dataclass
from pydantic import BaseModel

# TypedDict for structured returns
class UserData(TypedDict):
    id: str
    name: str
    email: str

@mcp.tool()
async def get_user_typed(user_id: str) -> UserData:
    '''Returns structured data - FastMCP handles serialization.'''
    return {"id": user_id, "name": "John Doe", "email": "john@example.com"}

# Pydantic models for complex validation
class DetailedUser(BaseModel):
    id: str
    name: str
    email: str
    created_at: datetime
    metadata: Dict[str, Any]

@mcp.tool()
async def get_user_detailed(user_id: str) -> DetailedUser:
    '''Returns Pydantic model - automatically generates schema.'''
    user = await fetch_user(user_id)
    return DetailedUser(**user)
```

### Lifespan Management

Initialize resources that persist across requests:

```python
from contextlib import asynccontextmanager

@asynccontextmanager
async def app_lifespan():
    '''Manage resources that live for the server's lifetime.'''
    # Initialize connections, load config, etc.
    db = await connect_to_database()
    config = load_configuration()

    # Make available to all tools
    yield {"db": db, "config": config}

    # Cleanup on shutdown
    await db.close()

mcp = FastMCP("example_mcp", lifespan=app_lifespan)

@mcp.tool()
async def query_data(query: str, ctx: Context) -> str:
    '''Access lifespan resources through context.'''
    db = ctx.request_context.lifespan_state["db"]
    results = await db.query(query)
    return format_results(results)
```

### Transport Options

FastMCP supports two main transport mechanisms:

```python
# stdio transport (for local tools) - default
if __name__ == "__main__":
    mcp.run()

# Streamable HTTP transport (for remote servers)
if __name__ == "__main__":
    mcp.run(transport="streamable_http", port=8000)
```

**Transport selection:**
- **stdio**: Command-line tools, local integrations, subprocess execution
- **Streamable HTTP**: Web services, remote access, multiple clients

---

## Code Best Practices

### Code Composability and Reusability

Your implementation MUST prioritize composability and code reuse:

1. **Extract Common Functionality**:
   - Create reusable helper functions for operations used across multiple tools
   - Build shared API clients for HTTP requests instead of duplicating code
   - Centralize error handling logic in utility functions
   - Extract business logic into dedicated functions that can be composed
   - Extract shared markdown or JSON field selection & formatting functionality

2. **Avoid Duplication**:
   - NEVER copy-paste similar code between tools
   - If you find yourself writing similar logic twice, extract it into a function
   - Common operations like pagination, filtering, field selection, and formatting should be shared
   - Authentication/authorization logic should be centralized

### Python-Specific Best Practices

1. **Use Type Hints**: Always include type annotations for function parameters and return values
2. **Pydantic Models**: Define clear Pydantic models for all input validation
3. **Avoid Manual Validation**: Let Pydantic handle input validation with constraints
4. **Proper Imports**: Group imports (standard library, third-party, local)
5. **Error Handling**: Use specific exception types (httpx.HTTPStatusError, not generic Exception)
6. **Async Context Managers**: Use `async with` for resources that need cleanup
7. **Constants**: Define module-level constants in UPPER_CASE
