How this task behaves.

No. The AI identifies the conflicts and suggests new dates, but you must manually update your calendar.

Does it support countries outside of the US, UK, Germany, and France?
No. It only retrieves data for the countries supported by the holiday_registry_tool.
- 04
Can I use this with Claude or Cursor?
Yes. Any MCP-compatible client works once you connect the Connector through Vinkius.
- 05
Does the AI delete my existing project files?
