Questions

What can the AI do in CalendarLink?

The AI can read your user and organisations, upcoming and past events, event RSVPs, collections, appearances and contacts. It can create add-to-calendar events and create or update collections.

Does the AI see my CalendarLink API token?

No. Your CalendarLink credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only and turn on creating events and collections later. Any tool can be set to need your approval before it runs. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

PipMCP has a free plan with no credit card required. Paid plans bill per completed task. You also need your own CalendarLink account.

What is the organisation ID for?

CalendarLink keeps events, collections and contacts under an organisation. PipMCP uses the organisation ID you enter in each of those calls. It is a UUID, and the tool that reads your current user lists the organisations you belong to.
