Context7

What you can do with Context7

Context7 pulls up-to-date, version-specific library documentation and code examples straight from the source into the model's context, so generated code stops relying on stale training data or invented APIs.

• ·Look up current usage of a library or API
• ·Generate code against a specific framework version
• ·Fetch setup or configuration steps for a service
• ·Target a known library by its Context7 ID

What Context7 can and cannot do

What you need before using Context7

Runtime

None for the remote server; Node.js 18+ for npx ctx7 setup or the @upstash/context7-mcp package

Credentials

API key recommended (free, from context7.com/dashboard); npx ctx7 setup obtains one via OAuth

Payment

Free API key raises rate limits; the README does not describe paid tiers

Connect Context7 and confirm it works

1. Run npx ctx7 setup and choose MCP mode (or CLI + Skills); it signs in via OAuth and generates an API key
2. Or add https://mcp.context7.com/mcp as an HTTP server with header Authorization: Bearer <API key>
3. Optionally add a standing rule (CLAUDE.md, Cursor Rules) telling the agent to use Context7 for library questions
