Installing Context7

A hosted server, connect to the endpoint, nothing to run locally.

Context7 is now hosted, the endpoint needs an API key sent as an `Authorization: Bearer <key>` header. `npx ctx7 setup` will wire this up for you across supported clients.

What it does

Context7 fetches current, version-specific documentation and code examples for libraries and feeds them to the assistant, cutting down on outdated or hallucinated APIs.

Like any MCP server, Context7 plugs into MCP-compatible assistants (such as Claude and other clients) so the model can use it as a tool , no custom integration code required.
