How to connect gemini cli to apple calendar

Pomeroy lists the assistants it finds on this Mac, so install Gemini CLI first if it is not there yet.

  1. 1

    Download Pomeroy and switch on Apple Calendar.

    Open the download, drag Pomeroy into Applications, and open it. Pomeroy opens a setup window listing every app it can connect. macOS asks whether Pomeroy may access your calendar. The prompt names Pomeroy, and nothing is requested until you flip the toggle.

  2. 2

    Press Set up beside Gemini CLI.

    Pomeroy runs Gemini CLI's own mcp add command with user scope, so Pomeroy is there in every project rather than one folder.

  3. 3

    Check Gemini CLI.

    Run gemini mcp list and pomeroy is listed. Inside a session, /mcp shows it with its tools. Start a new Gemini CLI session.

  4. 4

    Ask Gemini CLI something.

    Try “What’s on my calendar today?” and a real answer comes back.

The configuration, in full

Set up writes it for you. The documentation has the exact text, where it goes, and how to check it worked.

Can Gemini CLI see my Apple Calendar?

Yes. Once you switch Calendar on in Pomeroy, Gemini CLI can read today, any day, or a whole range of days, across every calendar your Mac shows. Times come back in your Mac's own time zone.

Can Gemini CLI change my calendar?

Yes, when you ask. Gemini CLI can create an event and change one you name, and it changes only the fields you mention. A recurring event changes only that one occurrence. It cannot delete an event.

Is it safe to connect Gemini CLI to Apple Calendar?

Pomeroy reads your calendar on your Mac and sends nothing to a Pomeroy server. What Gemini CLI reads becomes part of your conversation, the same as text you paste in. Calendar starts switched off, and you can switch it off again at any time. Pomeroy is an independent app, not made by Anthropic.

Gemini CLI does not show Pomeroy's tools.

Start a new Gemini CLI session; a running one keeps the tool list it started with. Then press Set up again in Pomeroy, under Settings › Assistants: every way Pomeroy sets an assistant up is safe to run twice. Pomeroy's menu bar shows whether Gemini CLI is connected right now.
