Context7

About Context7

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version-specific documentation and code examples for libraries and feeds them to the assistant, cutting down on outdated or hallucinated APIs.

Pull up-to-date library docs into the model.

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.

claude mcp add --transport http context7 https://mcp.context7.com/mcp

{
  "mcpServers": {
    "context7": {
      "type": "http",
      "url": "https://mcp.context7.com/mcp"
    }
  }
}

Not sure where the config file lives, or it isn't picking the server up? Config paths for every client.
