Frequently asked questions
Can I verify if a physical address is valid via AI?
Yes! Use the validate_physical_address tool and provide the address string. Your agent will return the structured, autocompleted data and verification status.
How do I check if an email address is active using the agent?
Use the validate_email tool. Provide the address, and Foxentry will check for syntax, domain validity, and if the specific mailbox actually exists.
Is it possible to retrieve business data using a registration number via AI?
Absolutely. Use the lookup_business_data query and provide the registration number. The agent will retrieve official company names and registered addresses.
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 Foxentry MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
