Find Fastly API methods, inspect their parameters, and run focused JavaScript with a preconfigured Fastly client. Investigate services, backends, TLS, caching, and traffic, or make changes with a token that permits them. The MCP server runs locally and uses the Fastly API token you configure in your client environment. Install Bun and Node.js 24.12.0 or newer before connecting. For production changes, review the planned call and approve it before execution.
