FAQ

Frequently asked questions

What information do I need to calculate a shipping price?

You need to provide the origin and destination ZIP codes (CEP), the service code (e.g., 04014 for SEDEX), weight, package format, and dimensions (length, height, width) using the calculate_price_deadline tool.

Can I track multiple objects at once?

The track_object tool currently processes one tracking code per request to ensure detailed event history for that specific item.

What is the 'idLote' field in the shipping calculation?

The idLote (Batch ID) is a required identifier for the Correios API request. It can be any string or number used to identify your specific calculation request in their logs.

How does the Vercel AI SDK connect to MCP servers?

Import createMCPClient from @ai-sdk/mcp and pass the server URL. The SDK discovers all tools and provides typed TypeScript interfaces for each one.
