What is the Correios API (REST) MCP Server?
Connect your AI agent to the Correios infrastructure to automate logistics queries in Brazil. This server provides direct access to the official REST API for real-time tracking and shipping simulations.
What you can do
- Object Tracking — Get the full history of events and current status for any valid tracking code (e.g., AA123456789BR) using the
track_objecttool. - Shipping Calculation — Simulate prices and delivery deadlines for various services like SEDEX and PAC based on weight, dimensions, and zip codes with
calculate_price_deadline. - Logistics Automation — Integrate shipping data into your e-commerce or support workflows without manual lookups.
How it works
- Subscribe to this server
- Enter your Correios API credentials (User and Password)
- Start querying logistics data from Claude, Cursor, or any MCP client
Who is this for?
- E-commerce Owners — quickly check delivery statuses for customers and provide proactive updates.
- Logistics Managers — automate shipping cost estimations for different regions in Brazil directly from the terminal or chat.
- Support Teams — provide instant tracking updates within AI-powered chat interfaces without leaving the conversation.

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 Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
