Is the NPS API Key free?

Yes! You can sign up for a free API key at nps.gov/subjects/developer by providing your name and email. The key is typically issued instantly.

How can I find the correct 'Park Code'?

You can find park codes by using the `list_parks` tool or by looking at the URL of a park on nps.gov (e.g., nps.gov/yose/ has the code 'yose').

What kind of alerts are provided?

The `list_alerts` tool provides information on park closures, safety warnings (like weather or fire conditions), and general notices about road work or facility changes.

National Park Service + Pydantic AI FAQ

Common questions about integrating National Park Service MCP Server with Pydantic AI.

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 National Park Service MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
