# oidc_proxy

# `fastmcp.server.auth.oidc_proxy`

OIDC Proxy Provider for FastMCP.

This provider acts as a transparent proxy to an upstream OIDC compliant Authorization
Server. It leverages the OAuthProxy class to handle Dynamic Client Registration and
forwarding of all OAuth flows.

This implementation is based on:
OpenID Connect Discovery 1.0 - [https://openid.net/specs/openid-connect-discovery-1\_0.html](https://openid.net/specs/openid-connect-discovery-1_0.html)
OAuth 2.0 Authorization Server Metadata - [https://datatracker.ietf.org/doc/html/rfc8414](https://datatracker.ietf.org/doc/html/rfc8414)

get_oidc_configuration(self, config_url: AnyHttpUrl, strict: bool | None, timeout_seconds: int | None) -> OIDCConfiguration
```

Gets the OIDC configuration for the specified configuration URL.

**Args:**

* `config_url`: The OIDC configuration URL
* `strict`: The strict flag for the configuration
* `timeout_seconds`: HTTP request timeout in seconds

#### `get_token_verifier` <sup><a href="https://github.com/PrefectHQ/fastmcp/blob/main/src/fastmcp/server/auth/oidc_proxy.py#L480" target="_blank"><Icon icon="github" style="width: 14px; height: 14px;" /></a></sup>

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