Context7: Documentation

Connection

• Remote: https://mcp.context7.com/mcp (Streamable HTTP), optional CONTEXT7_API_KEY header.
• Local: npx -y @upstash/context7-mcp.

Tools

• resolve-library-id — find a library by name (e.g. "next.js").
• query-docs — fetch docs and examples for a specific question.

Agent flow

Before writing code against an external library: resolve-library-id → query-docs → code from fresh docs, not from memory.
