Before you start

  • An account with permission to use the Google Calendar resources you intend to connect.
  • ChatGPT developer mode must be available to your account and allowed by your workspace.

  2. Choose the account and review access. Sign in to the Google account that has access to the intended resources. Review the permissions Google requests, then return to ApexGenius.
  3. Review the connected account and resources. Find Allowed resources on the connection page or its Tools tab. Choose Refresh and enable only the connected Calendar account. Resource selection does not add permissions to the Google account.
  4. Check the connection. Use Test connection or Check again and read the reported status. Add an AI agent from the AI agents page, choose Read only for the first test, and try the question below.

Create and change

  • create_eventCreate an event, with guests, a Meet link and reminders if you want.
  • update_eventChange an event’s time, title, guests or details.
  • respond_to_eventAccept, decline or answer maybe to an invite.
  • delete_eventDelete an event. Guests are told by default.

You choose what ChatGPT can use

When you approve ChatGPT, pick Full access, Read only, or Custom. Read only allows the Read operations and nothing else. Custom picks apps and tools one by one.

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.
