Updates the requirements on fastmcp to permit the latest version.

Release notes

Sourced from fastmcp's releases.

v3.4.2: Heads Up

FastMCP 3.4.2 restores JWT compatibility for providers that include private, non-critical JWS header parameters. Tokens from providers like Clerk can carry header metadata such as cat without being rejected before signature and claim validation, while unsupported critical headers are still rejected.

v3.4.1: Floor It

FastMCP 3.4.1 floors Starlette at >=1.0.1 so installs can no longer resolve to a version affected by CVE-2026-48710, which was previously only constrained transitively through mcp. It also makes OAuthProxy log refresh-token cache misses instead of failing silently.

Enhancements ✨

  • Log refresh-token misses in OAuthProxy instead of failing silently by @​jlowin in #4276

Security 🔒

Docs 📚

  • Document --notes-start-tag in release instructions by @​jlowin in #4275

Full Changelog: v3.4.0...v3.4.1

v3.4.0: Remote Control

FastMCP 3.4 is about reaching servers that live somewhere else. The headline is fastmcp-remote, a standalone bridge that connects stdio-only MCP hosts to servers hosted over HTTP. Around it, the proxy layer those connections depend on is hardened: a proxy now forwards initialize upstream and fails loudly when the backend is missing or misconfigured, instead of reporting a connected-but-empty proxy. And FastMCP-issued access tokens can now outlive short-lived upstream tokens, so authenticated sessions survive the long idle periods remote clients are prone to.

New Features 🎉
