MCP Server for AI Agents
We have introduced the Model Context Protocol (MCP) Server, a new interface that enables AI Agents to integrate directly with OnceHub’s scheduling workflow.
Why It Matters
- Natural Language Scheduling: Compatible AI Agents can now fetch available slots and schedule meetings using natural, conversational language.
- Built on Existing Booking API: The MCP Server acts as a new interface on top of OnceHub’s existing Booking API logic, no separate scheduling system is required.
- Designed for AI Driven Use Cases: Ideal for organizations building AI Agents for automated scheduling and customer interactions.
To learn how to configure and deploy your agent, please visit our developer center for the MCP Server guide and authentication requirements.
Once you are ready to connect, the dedicated Public MCP Endpoint for AI Agent calls is:

Who Can Access It
Plan: Available on Schedule Plan with API Key based authentication.

- Get Booking Details: Retrieves meeting details for a specific booking.
- Cancel Booking: Cancel a booking on your OnceHub account.
- Request Reschedule: Cancel a booking and automatically initiate a request for the guest to reschedule.
