This is a small helper that connects your AI assistant to the Calendar app on your Mac. Once it is set up, you can ask your AI things like what is on your schedule today, and it will actually look it up in your calendar instead of guessing. It is handy if you live in your calendar and want quick answers without clicking around.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. It cannot see your calendar or any other app on your computer. An MCP server is a small helper program that gives your AI one new skill, and this one gives it a connection to the Calendar app on your Mac. So when you ask about your schedule, the AI quietly asks this helper, the helper reads your calendar, and the AI tells you what it found.

What this MCP server does

You ask your AI a question about your schedule, like what is on today or when your next meeting is. The AI passes that request to this helper program running on your Mac. The helper reads the Calendar database file on your computer, finds the matching events, and hands them back. The AI then turns those events into a normal answer in the chat. It only reads, so it never adds, changes or deletes anything in your calendar.

“Find any events with the word budget in the title.”
“What meetings do I have between January 1 and January 31?”

What it gives back to you

You get back a list of events with the title, start and end time, whether it is an all day event, and its status. If you ask for details on one event, you also get the description, location, link and which calendar it belongs to. The AI usually rewrites this as a short, readable answer in the chat, like a mini agenda. Nothing in your calendar is changed.

Before you start
