Frequently asked questions
How do I find my Holiday API Key?
Log in to your Holiday API dashboard, and you will find your API Key on the main page. Copy and paste it below.
Does the agent support historical years?
Yes. Holiday API provides historical data. Depending on your plan, you can query holidays for past years to audit previous events.
Can the agent calculate the number of workdays?
Yes. The get_workdays_count tool allows your agent to calculate the exact number of non-holiday business days between two dates for any country.
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.
