Overview

## What OnceHub does

OnceHub handles meeting booking, and this connector gives an authenticated user control over their own scheduling from a conversation. Upcoming meetings can be listed, existing booking links retrieved, and a one-time link generated for a particular invitation.

Availability work is included: reviewing configured working hours and adjusting availability on specific dates. Meetings can be cancelled or rescheduled, and a confirmed meeting can be marked as a no-show after the fact. The connector stays within the scheduling setup belonging to the connected account, so it manages one person's calendar rules rather than a whole team's.

### Who it is for

People who take bookings through OnceHub and maintain their own availability rules.

### What stands out

It reaches past the booking itself into the follow-up, covering rescheduling, cancellation, and no-show marking.

## Where OnceHub is listed

OnceHub is listed in the ChatGPT apps directory only. OnceHub has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
