Bumps fastmcp from 3.4.4 to 3.4.7.

Release notes

Sourced from fastmcp's releases.

v3.4.7: Know Your Audience

FastMCP 3.4.7 restores CIMD private_key_jwt authentication for OAuthProxy deployments at a bare origin. Client assertions are now validated against the exact token endpoint advertised in authorization server metadata, eliminating the doubled-slash audience mismatch.

What's Changed

Security 🔒

Full Changelog: PrefectHQ/fastmcp@v3.4.6...v3.4.7

v3.4.6: Trust, but Proxy

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.

v3.4.5: Key Change

FastMCP 3.4.5 collects five fixes for the 3.x line. The one that prompted it: a single Ed25519 key in a JWKS — which Rauthy, Ory Hydra, and some Keycloak configurations publish by default — made JWTVerifier reject every token, including ones correctly signed by supported keys in the same set.
