How do I get the contact information for my state representative?
First, find the legislator using search_legislators with their name or district. Then, use the get_legislator_details tool with their ID to retrieve their official email, office address, and phone number.
How does Pydantic AI discover MCP tools?

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?
