mcp-docs-tool

MCP Documentation Tool

An MCP (Model Context Protocol) tool for Cursor that assists with coding by searching relevant documentation for different programming languages.

Features

• Search documentation for multiple programming languages:
  • Go (using go doc)
  • Rust (using cargo doc or rustup doc)
  • TypeScript (using typedoc or npm package lookups)
• Integrate directly with Cursor's AI features
• No HTTP server required - runs as a local process

Usage with Cursor

Project-specific Configuration

• Create a .cursor directory in your project root:

  mkdir -p .cursor
  

• Create a mcp.json file in the .cursor directory with the following content:

  {
    "mcpServers": {
      "documentation-search": {
        "type": "stdio",
        "command": "npx",
        "args": [
          "-y",
          "mcp-docs-tool@latest"
        ],
        "env": {}
      }
    }
  }
  

Global Configuration

• Create a .cursor directory in your home directory (if it doesn't exist):

  mkdir -p ~/.cursor
  

• Create or edit the mcp.json file in the ~/.cursor directory and add:

  {
    "mcpServers": {
      "documentation-search": {
        "type": "stdio",
        "command": "npx",
        "args": [
          "-y",
          "mcp-docs-tool@latest"
        ],
        "env": {}
      }
    }
  }
  

• The tool will now be available in all Cursor workspaces.

Example Queries

In Cursor's chat, you can ask the agent to use the documentation search tool:

• "Search for documentation on io.Reader in Go"
• "Find Rust documentation for std::collections::HashMap"
• "Get TypeScript documentation for express"

Publishing to npm

If you want to publish this package to npm:

• Make sure you have an npm account and are logged in:

  npm login
  

• Update the version in package.json if needed

• Publish the package:

  npm publish
  

Requirements

• Node.js 16+
• npm or yarn
• For language-specific documentation:
  • Go: Go toolchain installed
  • Rust: Rust toolchain with cargo and/or rustup
  • TypeScript: npm and optionally typedoc

Testing

node test.js

This will send test requests to the MCP server and display the responses.
