Context7
Upstash's documentation service supplies version-specific library documentation and code examples to coding agents through MCP or a CLI.
About Context7
Coding assistants can suggest outdated library APIs when their context lacks current documentation.
Who it’s for
- Developers using AI coding assistants
- Teams integrating documentation retrieval into agent workflows
When to consider it
Consider Context7 when you want your coding agent to retrieve documentation for a specific library and version while implementing a change.
Tradeoffs & limitations
- The MCP server is MIT licensed, but the API backend, parsing engine and crawling engine are private and absent from the repository.
- The ctx7 CLI requires Node.js 18 or newer; an API key is recommended for higher rate limits.
- The Free plan includes 1,000 API calls per month; Pro costs $10 per seat per month with 2,000 calls per seat, then $5 per 1,000 extra calls, and private repositories are parsed at $5 per million tokens.
