Calculate Brazilian shipping rates in Windsurf

The `calculate_price_deadline` tool lets your agent query the official Correios database to get real-time freight pricing and delivery times for Brazil. Cascade uses this tool to instantly fetch shipping costs based on zip codes, package weight, and physical dimensions. Instead of leaving your editor to check postal tables, you just tell Cascade to build a checkout page. Your agent calls this MCP Server, grabs the rates, and writes the shipping logic directly into your ecommerce code.

Track Brazilian packages autonomously

The `track_object` tool pulls the exact shipping history and current status of any Brazilian postal package. Cascade hooks into this endpoint to monitor active shipments and update your database without you writing a single line of API integration code. When a user asks Cascade to debug a stuck order, the agent grabs the tracking code, queries the Correios API (REST) server, and outputs the exact transit status. You get the full picture in your chat panel in seconds.

Chain shipping workflows with Windsurf Cascade

The `calculate_price_deadline` and `track_object` tools allow Cascade to chain multi-step shipping tasks using this MCP Server. You can instruct your agent to look up a customer's zip code, run the pricing calculation, and then generate a complete invoice draft. Cascade manages the entire execution sequence without asking for permission at every step. It reads the context of your workspace, calls the necessary Correios endpoints, and presents the finished code structure.

Common questions about Correios API (REST) MCP in Windsurf

Open your `~/.codeium/windsurf/mcp_config.json` file and add the server under the `mcpServers` key. Alternatively, open Settings, go to Cascade, find MCP Servers, and paste your Vinkius endpoint.

Yes, Cascade discovers the `calculate_price_deadline` and `track_object` tools immediately upon connection. It calls them autonomously when you ask questions about Brazilian shipping rates or package statuses.

No, this server communicates directly with the official Correios REST endpoints over HTTP. You do not need to install any local Python or Node.js libraries in your Windsurf workspace.

Vinkius handles all the authentication behind the scenes. You only need to add your single Vinkius token to your Windsurf configuration file to gain access to the Correios tools.

Yes, it is. Vinkius runs the server in an isolated, zero-trust V8 sandbox that destroys itself after execution. Only the zip codes, package dimensions, and tracking numbers sent to `track_object` or `calculate_price_deadline` are processed, and they are never stored.
