Ts Morph MCP Server

🚀 TypeScript Package Introspector (MCP Server)

A tool for introspecting TypeScript packages and source code, extracting exported symbols (functions, classes, types, constants) and their type information. It runs as a Model Context Protocol (MCP) server.

🚀 Quick Start

This tool can be run as an MCP server:

npx ts-introspect-mcp-server

To integrate it into your project, create a .roo/mcp.json configuration file:

{
  "mcpServers": {
    "ts-introspect": {
      "command": "npx",
      "args": ["-y", "ts-introspect-mcp-server"]
    }
  }
}

✨ Features

• Extract exported symbols from npm packages using type definitions.
• Analyze TypeScript source code directly.
• Obtain detailed type signatures for all exported symbols.
• Extract JSDoc comments as descriptions.
• Provide type information for large language models (LLMs) via MCP.
