Connect Claude & ChatGPT to FlexyBox

Ask your AI who is arriving today, which classes are full this week, or to check a party in when they arrive. It works with the FlexyBox Booking API: bookings, arrivals, classes, class bookings, events, participants and customers.

Try asking

“Who is arriving at the restaurant today?”
The AI gets today's arrivals for the department with arrival state, time, tables and open bill.
“Table for Jensen has arrived, 6 people instead of 4.”
It checks the booking in and sets the guest count to 6. No bill is opened.
“Which spinning classes next week still have free spots?”
It lists classes in that period and shows the bookings on each one.

1
Pick the app

Paste your key
Paste a Client ID and Client Secret. A FlexyBox system administrator creates them in the FlexyBox account portal; FlexyBox support cannot create them for you. PipMCP uses them to get access tokens, so there is no separate sign-in.
3

You get a personal MCP link. Add it to Claude, ChatGPT or Cursor:
Click your name, then Settings › Connectors › Add custom connector. Paste your link as the Remote MCP server URL. Switch it on from the + menu in a chat.

Questions

What can the AI do in FlexyBox?

It can search customers, list and read bookings, see a department's arrivals and booking calendar, check bookings in, mark no-shows and cancel bookings. It can list classes and class bookings, cancel them and message participants, and list events and participants and check them in.

Does the AI see my FlexyBox credentials?

No. Your FlexyBox 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. Cancelling a booking can refund payments, cancelling a class can email or text everyone booked, and messages go out at once, so these can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT, open Settings › Apps & Connectors › Advanced, turn on Developer mode and 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?

FlexyBox connects with OAuth client credentials, and OAuth connections need the PipMCP Pro plan or above. PipMCP also has a free plan with no credit card, but it does not include this connection. Paid plans bill per completed task. You also need your own FlexyBox system. PipMCP is an independent service and is not affiliated with FlexyBox.

Which FlexyBox API does this use?

It uses the FlexyBox Booking API, which covers bookings, arrivals, classes and events. POS, products and loyalty are separate FlexyBox APIs and are not part of this connection.
