Perplexity

Run Brazilian shipping queries from the CLI

The `calculate_price_deadline` tool queries the Correios REST API to calculate shipping costs and delivery times directly from your terminal. Claude Code executes this tool to output raw JSON or formatted tables of postal rates. You can pipe this shipping data into shell scripts or use it to quickly test shipping configurations. There is no need to write a curl command or open a browser to check a Brazilian zip code.

Track Correios packages via Claude Code

The `track_object` tool pulls the complete tracking history for any Brazilian postal package. Claude Code runs this tool to show you the current location, status, and timestamps of your shipments. This is perfect for DevOps engineers or SREs who need to check delivery statuses during automated cron jobs. You can run a single terminal command and get the raw tracking status instantly.

Automate postal checks with this MCP Server

The `calculate_price_deadline` and `track_object` tools integrate directly with Claude Code's headless terminal environment through this MCP Server to automate repetitive shipping tasks. You can instruct the CLI to read a list of tracking codes from a text file and run the tracking tool on each one. Your terminal agent processes the list, formats the results, and writes them to a clean report. This gives you fast, scriptable access to Brazilian shipping data without writing any custom integration scripts.
