About

Language models go stale the moment a library ships a new version, and agents happily write code against last year's docs. Context7 is a free MCP server that fetches up-to-date, version-specific documentation on demand, so your agent reads today's docs instead of its training data. It is MIT licensed, installs with one command into any MCP-compatible client, and an optional free API key raises the rate limits. If your coding agent keeps inventing API methods that do not exist, this is the fix.

Details

Open source. You run it yourself.

Auth: Open source (MIT)

Rate limit: Free; optional free API key raises limits
