# `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 GoogleDCRProvider
|
|
|
|
# Simple Google OAuth protection
|
|
auth = GoogleDCRProvider(
|
|
client_id="your-google-client-id.apps.googleusercontent.com",
|
|
client_secret="your-google-client-secret"
|
|
)
|
|
|
|
mcp = FastMCP("My Protected Server", auth=auth)
|
|
```
|
|
|
|
|
|

### `GoogleTokenVerifier` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/server/auth/providers/google.py#L89" 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/jlowin/fastmcp/blob/main/src/fastmcp/server/auth/providers/google.py#L111" 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.
|
|
|
|

### `GoogleDCRProvider` <sup><a href="https://github.com/jlowin/fastmcp/blob/main/src/fastmcp/server/auth/providers/google.py#L208" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>
|
|
|
|
|
|
Complete Google OAuth DCR provider for FastMCP.
|

a base URL, and you're ready to go.
|
|
