FAQ

Frequently asked questions

How can I calculate the shipping price for a specific package?

Use the calculate_prices tool. You will need to provide the origin and destination ZIP codes, weight, dimensions, and the service code (e.g., 04014 for SEDEX).

Can I check the delivery deadline between two Brazilian cities?

Yes! The estimate_delivery_time tool allows you to input the service code and both ZIP codes to receive the estimated delivery time in working days.

Is it possible to find an address using only the ZIP code (CEP)?

Absolutely. Use the consult_cep tool with the 8-digit ZIP code to retrieve the street name, neighborhood, city, and state automatically.

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 Correios do Brazil MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
