Description

echo(text)

Auth

Pass a Authorization: Bearer <token> header. The server tries all registered providers in order:

  1. Google — verifies Google ID tokens via google-auth

  2. JWT — verifies JWTs signed with JWT_SECRET

Extending

Add a new provider:

  1. Implement AuthProvider in src/auth/your_provider.py

  2. Register it in server.py: registry.register("name", YourProvider())

No other changes needed.
