Transport matrix

• stdio: local process (command, args, optional env)
• sse: remote endpoint (url, optional headers / auth)
• streamable-http: modern HTTP transport (url, optional headers / auth)

The universal recipe spec allows multiple transports; adapters choose one supported transport during setup.
