TypeScript Package Introspector (MCP Server)

This tool introspects TypeScript packages and source code to extract exported symbols (functions, classes, types, constants) and their type information. It runs as a Model Context Protocol (MCP) server.

Features

Extract exported symbols from npm packages using their type definitions
Analyze TypeScript source code directly
Get detailed type signatures for all exported symbols
Extract JSDoc comments as descriptions
Provide type information to LLMs through MCP

Usage

This tool can be run as an MCP server to provide TypeScript package introspection capabilities to LLM applications like Claude for Desktop. You can start it using npx:

npx ts-introspect-mcp-server

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

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