Fastmcp Boilerplate

FastMCP supports stdio, HTTP streaming, and SSE transports; HTTP streaming exposes both a streaming endpoint and an SSE endpoint for compatibility.

Yes — FastMCP provides a stateless mode for HTTP streaming where each request is handled independently and no persistent sessions are stored, making it suitable for serverless or load‑balanced deployments.

Authentication is provided by an authenticate function supplied in server options that returns an authentication context; FastMCP also includes built‑in OAuth discovery endpoints and supports JWT validation for OAuth flows.

Tools can return text, images, audio, resource references, or combinations thereof. Streaming partial results and progress notifications are also supported.
