+**[v3.4.6: Trust, but Proxy](https://github.com/PrefectHQ/fastmcp/releases/tag/v3.4.6)**
+
+FastMCP 3.4.6 backports trusted-proxy support for SSRF-protected OAuth metadata and JWKS fetches. Deployments can now route these requests through a mandated corporate proxy while preserving custom CA certificates; FastMCP refuses the fetch when no proxy is configured instead of risking an unprotected direct request.
