Context7's MIT license covers only the client: the MCP server, CLI and SDK. The API backend, parsing engine and crawling engine that build and serve the documentation index are private and reachable only through a hosted endpoint with an API key, so an open license over the client does not make the engine open source.

  README, numbered note: 'This repository hosts the MCP server's source code. The supporting components - API backend, parsing engine, and crawling engine - are private and not part of this repository.' Setup instructions point at the hosted server URL https://mcp.context7.com/mcp with an API key passed as a bearer token.

Adoption is measured by npm downloads of the @upstash/context7-mcp package, which is the published MCP server rather than the hosted documentation index itself. Upstash publishes no call count for the hosted index, so downloads of the client package are the only usage signal available.

Context7 resolves a library name to an id, then returns matching documentation and code examples for it: a find step followed by a content step, which puts it level with Jina Reader. Its corpus is documentation rather than the open web, but that affects what it covers, not what it does with a query.

  The MCP tools: "resolve-library-id: Resolves a general library name into a Context7-compatible library ID" and the docs tool that "Retrieves documentation for a library using a Context7-compatible library ID". The CLI mirrors both.
