# `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:
    ```python
    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)
    ```

Token verifier for Google OAuth tokens.

Google OAuth tokens are opaque (not JWTs), so we verify them
by calling Google's tokeninfo API to check if they're valid and get user info.


**Methods:**

#### `verify_token` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/server/auth/providers/google.py#L88" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python
verify_token(self, token: str) -> AccessToken | None
```

Verify Google OAuth token by calling Google's tokeninfo API.


### `GoogleProvider` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/server/auth/providers/google.py#L185" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
