Frequently asked questions
Can I cancel a booking directly from the chat?
Yes. Provide the Appointment ID to the 'cancel_calenso_appointment' tool, and the AI agent will remove it from your schedule.
How do I add a new customer profile?
Invoke the 'create_calenso_customer' tool with a JSON object containing the customer's details (like name and email).
Is it possible to query available staff members?
Yes, just use the 'list_calenso_staff' tool to pull the active roster of your bookable employees.
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 Calenso MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
