mcp_server_fhir

The `fastmcp_server.py` explicitly imports the `Auth` and `AuthConfig` utilities, indicating an intent for secure FHIR server access. However, the `ensure_auth` function, which is called by all tools, has the critical token acquisition and application (`fhir_client.set_access_token(access_token)`) commented out. This means the server, as provided, will attempt to connect to FHIR endpoints without any authentication. This is a severe security vulnerability if the target FHIR server contains sensitive patient data and requires authorization. Hardcoded `FHIR_URL` values for testing purposes are also present in `test_change_observation_category.py` and `fastmcp_server.py` which could lead to misconfigurations in production environments. No 'eval' or direct code injection vulnerabilities were found, but the default lack of authentication is critical.
