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.

Every tool call from LlamaIndex to the Correios API (REST) MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
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 LlamaIndex connect to MCP servers?
Use the MCP client adapter to create a connection. LlamaIndex discovers all tools and wraps them as query engine tools compatible with any LlamaIndex agent.
Can I combine MCP tools with vector stores?
Yes. LlamaIndex agents can query Correios API (REST) tools and vector store indexes in the same turn, combining real-time and embedded data for grounded responses.
Does LlamaIndex support async MCP calls?
Yes. LlamaIndex's async agent framework supports concurrent MCP tool calls for high-throughput data processing pipelines.
