Bumps fastmcp from 3.4.4 to 3.4.5.

Release notes

Sourced from fastmcp's releases.

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.

v4.0.0b1: Fourgone Conclusion

FastMCP 4 rebuilds the framework on the MCP Python SDK v2, and this beta is the first release to run on the SDK's stable 2.0. The SDK v2 rewrote the protocol layer end to end — protocol types moved into a standalone mcp_types package, every model field renamed from camelCase to snake_case in Python, and the server's request-handling model replaced — and FastMCP absorbs nearly all of it, so most FastMCP 3 servers run untouched. On that foundation v4 serves the sessionless 2026-07-28 protocol and the older handshake from one server, adds stateless session state and background tasks, makes protocol extensions a first-class surface, and removes server-initiated sampling and roots from the server API.

New Features 🎉

  • Migrate to MCP Python SDK v2 by @​jlowin in #4437
  • Teach fastmcp.Client the modern protocol: mode negotiation, MRTR driver, response cache by @​jlowin in #4450
  • Forward-port Hugging Face auth provider by @​jlowin in #4475
  • Add server-side identity assertion (SEP-990 ID-JAG) by @​jlowin in #4483
  • Add guard-mode multi-round-trip tools (SEP-2322) by @​jlowin in #4544
  • Add FastMCP-native server extension API (SEP-2133) by @​jlowin in #4602
  • Add stateless session state (UserSession / SessionId) by @​jlowin in #4604
  • Add background tasks via the io.modelcontextprotocol/tasks extension (SEP-2663) by @​jlowin in #4603
