Correios: Rastreamento

What Correios: Rastreamento does

Correios: Rastreamento MCP server gives AI clients access to tracking lookups from an official Correios source. Its single capability is exposed as correios_rastreamento_consultar, which agents can use to request tracking information. The server is read-only: it does not provide operations that modify records or update data at the source.

The hosted service is intended for use from an MCP-compatible AI client. The public repository contains the wrapper, manifests, documentation, and agent skills, while the operational MCP server runs at the platform endpoint. The hosted server itself is proprietary, even though the repository is released under the MIT license.

How it works

Clients connect over MCP over HTTP to:

https://api.mcp.ai/p_correios_rastreamento

After connection, an agent can invoke the tracking tool as needed. The service uses a passwordless magic-link login rather than a platform password. Billing is usage-based: requests consume credit from a prepaid wallet, so the deployment should have available balance before agents make lookups.

Returned tool data is sent to the LLM host selected by the user, such as Claude, ChatGPT, Cursor, or another agent host. That host is identified in the project documentation as a subprocesser, and the project recommends considering plans with training opt-out where applicable.

Setup and configuration

To add Correios: Rastreamento, configure an MCP client that supports HTTP with the hosted URL above. The README provides one-click installation paths for Claude Web and Claude Desktop, Cursor, and VS Code with Copilot Chat. Other clients can use the same endpoint if they support MCP over HTTP.

The documented client list includes Claude Desktop, Cursor, VS Code, Cline, and Continue. ChatGPT, Manus, OpenClaw, and other MCP-over-HTTP clients are also identified as compatible in the project material. No local package, API key, or environment variable is documented as required for this hosted setup. Login is handled through a magic link, and use is charged against prepaid credit.

Tools and capabilities

Only one tool is listed:

• correios_rastreamento_consultar: performs a Correios tracking consultation using the official source.

The available operation is deliberately narrow. It supports retrieving tracking information, not changing shipment data, managing Correios accounts, or performing other postal-service actions.

Limitations and notes

Correios: Rastreamento is a hosted, pay-per-query service rather than a locally run server. The repository does not represent the hosted implementation itself; it provides public project materials around that service. A client must support MCP over HTTP, and the user must complete the service’s magic-link login flow.

Because the tool is read-only, it cannot alter information at the source. The service also does not remove the selected LLM host from the data path: results are passed to that host. Review the provider’s privacy and training settings before sending tracking queries through an agent. Prepaid credit is another operational requirement; depleted credit may prevent further paid lookups.
