Context7 MCP Server

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

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

• "What are the main features of React hooks?"
• "How do I implement authentication with Next.js?"
• "Show me documentation for Upstash Redis"
• "Get examples of using React Query"

Usage

Requirements

• Node.js >= v18.0.0
• Cursor, Windsurf, Claude Desktop or another MCP Client
