How do I connect Claude or ChatGPT?

With Claude or ChatGPT connected, you plan in the chat and it lands in your year: “Add the tour dates to my calendar” or “What is coming up in March?” The assistant sees your scenarios, calendars, events and projects, and can change them. You use your own Claude or ChatGPT account for this.

The connection starts in Claude or ChatGPT, not in AnnuCal. You enter one address there, once.

Get the address

1. Click the + next to your calendar tabs.
2. Click AI & automation.
3. Click Set up next to Claude or ChatGPT.
4. Click Copy next to the address connect.annucal.com/mcp.

Enter it in Claude

1. In Claude, at the top of the left sidebar, click Customize, then the Connectors tab.
2. Click the black Add button at the top right, then Add custom connector.
3. Name it “AnnuCal”, paste the address and click Add.
4. Claude now shows AnnuCal with a Connect button. Click it.
5. Your browser opens. Click Continue connection, then Allow in the AnnuCal window. In Claude in the browser, the first of the two is skipped.

This works with free Claude too.

Enter it in ChatGPT

1. Open ChatGPT in the browser. In the left sidebar, click Plugins, then Add, then Add custom MCP server.
2. Name it “AnnuCal”, paste the address and choose OAuth as authentication.
3. Tick I understand and want to continue, then click Create as a plugin.
4. ChatGPT opens an AnnuCal window. Click Allow.

At the moment this works with ChatGPT Pro, Business and Enterprise.

Start

Open a new chat and ask for what you need. If you keep several scenarios, the assistant asks which one you mean.

Disconnect

Open AI & automation again, or Connections in your account, and click Disconnect next to the assistant. It can no longer access your year from that moment. Your events stay as they are.
