fastmcp.server.auth.providers.google

Google OAuth provider for FastMCP. This module provides a complete Google OAuth integration that’s ready to use with just a client ID and client secret. It handles all the complexity of Google’s OAuth flow, token validation, and user management. Example: 
from fastmcp import FastMCP
from fastmcp.server.auth.providers.google import GoogleProvider

# Simple Google OAuth protection
auth = GoogleProvider(
    client_id="your-google-client-id.apps.googleusercontent.com",
    client_secret="your-google-client-secret"
)

mcp = FastMCP("My Protected Server", auth=auth)

verify_token(self, token: str) -> AccessToken | None
Verify Google OAuth token by calling Google’s tokeninfo API.
