AgentOS now supports user-supplied FastAPI-compatible middleware and includes a built-in JWT middleware for token validation and claims extraction. This reduces boilerplate, standardizes authentication across channels, and gives platform teams a consistent place to enforce policies.

**Details**

- Plug in custom middleware for logging, tracing, rate limiting, or policy enforcement.
- Enable the JWT middleware to validate tokens and pass claims to agents and tools with minimal setup.

**Who this is for:** Platform and security teams standardizing auth and governance for AI applications.
