Google OAuth Example

Demonstrates FastMCP server protection with Google OAuth.

Setup

1. Create a Google OAuth 2.0 Client:

   • Go to Google Cloud Console
   • Create or select a project
   • Go to APIs & Services > Credentials
   • Create OAuth 2.0 Client ID (Web application)
   • Add Authorized redirect URI: http://127.0.0.1:8000/auth/callback
   • Copy the Client ID and Client Secret

2. Set environment variables:

   export FASTMCP_SERVER_AUTH_GOOGLE_CLIENT_ID="your-client-id.apps.googleusercontent.com"
   export FASTMCP_SERVER_AUTH_GOOGLE_CLIENT_SECRET="your-client-secret"
   

3. Run the server:

   python server.py
   

4. In another terminal, run the client:

   python client.py
   

The client will open your browser for Google authentication.
