Frequently asked questions
Can I cancel a booking using the agent?
Yes! Use the cancel_booking tool with the Booking ID. Your agent will trigger the cancellation in Cal.com, notifying all participants automatically.
How do I see the list of all my upcoming meetings?
Simply ask the agent to list_bookings. It will retrieve the list of all scheduled meetings from your Cal.com account, including start times and attendee details.
Does the integration allow creating a new event type?
Yes. Use the create_event_type action and provide the title, slug, and duration. The new scheduling template will be created in your account instantly.
How does Pydantic AI discover MCP tools?
Create an MCPServerHTTP instance with the server URL. Pydantic AI connects, discovers all tools, and generates typed Python interfaces automatically.
Does Pydantic AI validate MCP tool responses?
Yes. When you define result types as Pydantic models, every tool response is validated against the schema. Invalid data raises a clear error instead of silently corrupting your pipeline.
Can I switch LLM providers without changing MCP code?
Absolutely. Pydantic AI abstracts the model layer. your Cal.com MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
