prompts.chat

prompts.chat provides an MCP-first API for searching and discovering AI prompts programmatically. Use the MCP endpoint directly with any MCP-compatible client, or make standard HTTP requests.

MCP-First API

Our API is built on the Model Context Protocol (MCP), enabling seamless integration with AI assistants, IDEs, and automation tools. The same endpoint works for both MCP clients and traditional REST-style requests.

# MCP Endpoint

POST https://prompts.chat/api/mcp

Using with MCP Clients

Add prompts.chat to your MCP client configuration:

{
  "mcpServers": {
    "prompts-chat": {
      "url": "https://prompts.chat/api/mcp"
    }
  }
}

Compatible with Claude Desktop, Cursor, Windsurf, and other MCP-enabled tools.

MCP Prompts

All public prompts are exposed as native MCP prompts. This allows MCP clients to list and use prompts directly via slash commands or prompt pickers. You can filter prompts by category or tag using URL query parameters.

# Filter by users (one or more usernames)
"prompts-chat": {
  "url": "https://prompts.chat/api/mcp?users=f,torvalds"
}

# Filter by categories
"prompts-chat": {
  "url": "https://prompts.chat/api/mcp?categories=coding,marketing"
}

# Filter by tags
"prompts-chat": {
  "url": "https://prompts.chat/api/mcp?tags=chatgpt,writing"
}

# Combine filters
"prompts-chat": {
  "url": "https://prompts.chat/api/mcp?users=f&categories=coding&tags=js"
}

prompts/list

Browse all available prompts with pagination support.

prompts/get

Retrieve a prompt by ID. Variables (${name} or ${name:default}) are automatically substituted with provided arguments.

# List prompts
curl -X POST https://prompts.chat/api/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc": "2.0", "id": 1, "method": "prompts/list"}'

# Get a specific prompt with arguments
curl -X POST https://prompts.chat/api/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{
    "jsonrpc": "2.0",
    "id": 2,
    "method": "prompts/get",
    "params": {
      "name": "code-review-assistant",
      "arguments": { "topic": "AI safety" }
    }
  }'

Available Tools

search_prompts

Search for AI prompts by keyword. Returns matching prompts with title, description, content, author, category, and tags.

Parameter	Type	Required	Description
query	string	Yes	Search query to find relevant prompts
limit	number	No	Maximum results (default: 10, max: 50)
type	string	No	Filter by type: `TEXT`, `STRUCTURED`, `IMAGE`, `VIDEO`, `AUDIO`

get_prompt

Get a prompt by ID. If the prompt contains template variables (like ${variable} or ${variable:default}), the MCP client will be asked to provide values through elicitation.

Parameter	Type	Required	Description
id	string	Yes	The ID of the prompt to retrieve

Variable Elicitation

When a prompt contains variables like ${name} or ${topic:default value}, MCP clients that support elicitation will prompt the user to fill in these values. Variables with default values (after the colon) are optional. The prompt content will be returned with variables replaced.
