What credentials do I need for this MCP?

You need your Username, Password, and Contract Number from the Correios Web Services Portal. You may also need a Card ID for specific billing setups.

Can I use this to track any package in Brazil?

Yes, the MCP can track any object that uses the Correios tracking system via the track_object capability.

Does it support both PAC and SEDEX?

Yes, the capability can calculate prices and delivery deadlines for both PAC and SEDEX services.

How does address validation work?

You provide a Brazilian CEP, and the MCP retrieves the corresponding street, neighborhood, and city information.

Do I need to host this myself?

No, Vinkius hosts the MCP and manages the connection, so you only need to connect your AI client once.

Can my AI automatically track a package just by providing the tracking code?

Yes! Use the track_object capability with the tracking code (e.g., 'QI123456789BR'). Your agent will retrieve the current status, location, and the full history of logistics events.

MCP VERIFIED · PRODUCTION READY · VINKIUS GUARANTEED

Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Automate a task

Put Correios to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Correios works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Correios to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.
