Limits in Google Calendar

  • · The connected Google account decides which calendars can be read and changed.
  • · When your AI adds, changes or cancels an event with guests, Google emails them unless the call says not to.
  • · Enabled writes run immediately. Turn a tool off to block calls.
  • · Disconnecting stops future access. It does not undo an event change or recall an email.

Questions people ask first

How do I connect Google Calendar?

Open Google Calendar in ApexGenius Connections, choose Connect, and sign in with the Google account for the calendar you want.

Which calendars can my AI see?

The calendars the connected Google account owns or subscribes to, and other calendars shared with it when your AI names them.

Will my AI email my guests?

Google emails guests when an event with guests is created, changed or cancelled, unless your AI is asked to turn that off. Say so in your request when you do not want it.

Can my AI cancel events?

Yes. Deleting an event is marked destructive. Enabled writes run immediately. Turn a tool off to block calls.

Will this list of tools change?

Google publishes the Calendar MCP tools, and ApexGenius reads Google’s live list on every search. This page shows the list as of its review date.
