Frequently asked questions
Can my AI automatically track a package just by providing the tracking code?
Yes! Use the track_object tool with the tracking code (e.g., 'QI123456789BR'). Your agent will retrieve the current status, location, and the full history of logistics events.
How do I calculate shipping prices for PAC or SEDEX?
Use the calculate_shipping tool with the origin and destination CEPs, along with the weight and dimensions of the package. The agent will return the estimated price and delivery deadline.
Can I retrieve the full address details from a zip code (CEP)?
Yes! The search_cep tool allows your agent to fetch the street name, neighborhood, city, and state associated with any valid Brazilian zip code.
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 (Brazil) MCP integration works identically with OpenAI, Anthropic, Google, or any supported provider.
