McpDocServer MCP Server

What is McpDocServer?

McpDocServer is an MCP (Model Context Protocol) server for development framework documentation. It provides multi-threaded documentation crawling, local document loading, keyword search, and document detail retrieval. It is designed to solve AI hallucination problems in Cursor by delivering accurate, up-to-date API information directly from official sources.

How to use McpDocServer?

Clone the repository, optionally set PUPPETEER_SKIP_DOWNLOAD to skip Puppeteer’s Chrome download, then run npm install. Create a crawler config in config/doc-sources.js and run npm run crawl to fetch documentation into the docs/ folder. Start the server with npm start. The server exposes two MCP tools: search_docs (search with optional source/limit) and get_doc_detail (get page content by ID). Integrate with Cursor by adding the absolute path to server.js in your mcp.json.
