Who it is for
People who take bookings through OnceHub and maintain their own availability rules.
OnceHub
Meeting scheduling, availability, and booking link management
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.
What stands out
It reaches past the booking itself into the follow-up, covering rescheduling, cancellation, and no-show marking.
Availability
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.
