Context7 MCP Server

In this repository, we provide an MCP Server for Context7, which offers access to high-quality documentation for popular libraries.

This lets you use Cursor, Windsurf, Claude Desktop, or any MCP Client, to use natural language to search and access documentation for libraries, e.g.:

• "What are the main features of React hooks?"
• "How do I implement authentication with Next.js?"
• "Rate limiting with Redis"
• "Get examples of using React Query"

Usage

Requirements

• Node.js >= v18.0.0
