Mcpbook is a high-performance Model Context Protocol (MCP) server designed to convert public documentation websites into readily accessible knowledge bases for AI assistants. Originally optimized for GitBook, it boasts universal compatibility with various documentation platforms, including Vercel docs, Next.js sites, and Docusaurus. By scraping, indexing, and exposing content via both MCP tools and a REST API, Mcpbook enables AI models to intelligently search, retrieve specific pages, and extract structured information like code blocks, significantly enhancing AI's ability to provide context-aware responses and support.
