Connect Claude & ChatGPT to WhatTime

Ask your AI when you are free on a booking page, who booked a meeting, or to move one to another day. It can book meetings, reschedule or cancel them, search reservations by guest, and read or update your availability schedules. It also reads booking pages, routing forms and organization members.

Try asking

“Which slots are free on my consultation booking page on Friday?”
The AI finds the booking page and lists its free time slots for that date.
“Book a meeting with Kim Park on 14 May at 10:00.”
It creates the meeting with the guest's name, date and time. The guest may be notified.
“Move my meeting with Kim Park to Thursday at 15:00.”
It finds the meeting and reschedules it, with a reason if you give one. The guest is notified.

Questions

What can the AI do in WhatTime?

The AI can list and read booking pages, free slots, meetings, reservations, availability schedules, routing forms, users and organization members. It can book, reschedule and cancel meetings and update availability schedules.

Does the AI see my WhatTime credentials?

No. Your WhatTime API token is encrypted at rest and never shown to the AI. After you save it, it is 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 with lookups only. Booking and rescheduling can notify the guest, and cancelling a meeting cannot be undone, so these can require your approval before they run. 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 WhatTime account.

Which WhatTime plan do I need?

The WhatTime API is only available on WhatTime's Enterprise plan, so you need that plan to issue an API token. You issue it in WhatTime under 서비스 연동 (Integrations) > API, Webhook.
