Frequently asked questions
Can I search for specific keywords across all government documents?
Yes! Use the search_govinfo tool with Lucene syntax to perform complex queries. You can filter by date, collection, or specific fields to find exactly what you need.
How do I get the actual text or PDF of a bill?
Use the get_package_content tool with the specific packageId and choose your preferred format (pdf, xml, mods, etc.) to retrieve the document content.
What types of document collections are available?
Run the list_collections tool to see all available sources. Common codes include 'BILLS' for Congressional Bills, 'FR' for the Federal Register, and 'CPD' for Compilation of Presidential Documents.
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 GovInfo (GPO Legislative Docs) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
