opened on Dec 26, 2025

The include_tags and exclude_tags parameters on FastMCP were deprecated in v3.0.0.

Users should use the new visibility API instead:

  • server.enable(tags=..., only=True) instead of include_tags
  • server.disable(tags=...) instead of exclude_tags

See Upgrade Guide for migration details.
