Context7: Documentation

Connection

• Remote: https://mcp.context7.com/mcp (Streamable HTTP), optional CONTEXT7_API_KEY header.
• Local: npx -y @upstash/context7-mcp.
• Quick client setup: npx ctx7 setup.

Tools

• resolve-library-id — find a library by name (e.g. "next.js") and get its Context7 ID with relevance ranking.
• query-docs — fetch version-specific docs and code examples for a specific question about the resolved library.

Agent flow

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

Limits and pricing

• Free — $0, 1,000 calls/month (+20 bonus calls a day once the limit is hit), public libraries only.
• Pro — $10/seat/month, 5,000 calls included, private repos and team collaboration, extra calls at $10 per 1,000.
• Enterprise — $2.5 to $30 per user/month depending on team size, SSO/SAML, self-hosted option.
• Works without an API key too, at a lower rate limit; a free key is available at context7.com/dashboard.
