Frequently asked questions
Can my agent create events using natural language phrases like in the Fantastical app?
Yes. Use the 'create_event' tool. Fantastical's engine is designed to parse phrases like 'Lunch with Bob at 1pm next Tuesday'. The agent will transmit the string and return the structured event data flawlessly.
How do I see my available scheduling links (Openings) via chat?
Use the 'list_openings' tool. Your agent will retrieve all your active scheduling pages, providing the booking link URLs and duration settings so you can share them with others easily.
Can I suggest multiple meeting times to someone through the agent?
Absolutely. Use the 'list_proposals' tool to monitor existing suggestions. Fantastical Proposals allow you to offer several slots to attendees, and your agent can help you track their responses and finalize the event.
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 Fantastical MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
