# `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  theme={"theme":{"light":"snazzy-light","dark":"dark-plus"}}
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)
```

## Classes

### `GoogleTokenVerifier` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/auth/providers/google.py#L40" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

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/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/auth/providers/google.py#L67" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

```python  theme={"theme":{"light":"snazzy-light","dark":"dark-plus"}}
verify_token(self, token: str) -> AccessToken | None
```

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

### `GoogleProvider` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/auth/providers/google.py#L168" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

Complete Google OAuth provider for FastMCP.

This provider makes it trivial to add Google OAuth protection to any
FastMCP server. Just provide your Google OAuth app credentials and
a base URL, and you're ready to go.

Features:

* Transparent OAuth proxy to Google
* Automatic token validation via Google's tokeninfo API
* User information extraction from Google APIs
