Bumps fastmcp from 3.4.4 to 4.1.0.

Release notes

Sourced from fastmcp's releases.

v4.1.0: Fourth and One

FastMCP 4.1.0 is a maintenance release at heart: a broad sweep of fixes across OpenAPI, proxies, auth, tasks, and the CLI, plus full Python 3.15 support. It doesn't change how most servers behave. A few security fixes do tighten inputs that FastMCP previously accepted, though, and our versioning policy keeps breaking changes out of patch releases, so this ships as a point-one release.

Check these before upgrading:

  • MultiAuth now qualifies client IDs by source, so existing MultiAuth sessions and tasks start new ownership scopes. Finish pending tasks before upgrading.
  • Regex tool search uses Pydantic's regex engine, which doesn't support lookarounds or backreferences.
  • Skill files must resolve inside their configured directories.
  • OpenAPI path parameters reject . and .. segments.
  • HTTP sessions now expire after the MCP SDK's 30-minute idle default instead of never.
  • CodeMode requires Monty 1.1, which renames max_duration_secs to max_feed_duration_secs.

Thanks to our 48 contributors, including 21 first-time contributors!
