What security technologies does Auth Example utilize?

It leverages Nginx for bearer token authentication, Envoy as a powerful reverse proxy, and Open Policy Agent (OPA) for declarative, fine-grained authorization policy enforcement for the FastMCP server.

Is Auth Example easy to set up and test?

Yes, Auth Example comes with a complete Docker Compose setup, allowing you to quickly build and deploy all components (Nginx, Envoy, OPA, FastMCP server) with a single command. It also includes example Python clients for easy testing of both access types.

How does Auth Example handle authentication and authorization?

Authentication is managed at the Nginx proxy layer via bearer tokens. For authorization, Envoy integrates with OPA, which evaluates policies to determine access rights based on real-time request attributes.

Showcases a FastMCP server with both authenticated and unauthenticated endpoints, secured by Nginx, Envoy, and Open Policy Agent.

This project provides a comprehensive example of how to implement authentication and authorization for a FastMCP server. It features an unauthenticated MCP server alongside an authenticated path secured by an Nginx proxy for Bearer token enforcement, an Envoy reverse proxy for request forwarding, and Open Policy Agent (OPA) for fine-grained authorization decisions. The repository includes a full Docker Compose setup to easily deploy all components and example Python clients for testing both authenticated and unauthenticated access patterns.
