## Description

You can stop manually calculating shipping totals in a spreadsheet. This MCP gives your AI client the specific tools needed to manage postage expenses. When you're planning a shipment, your agent can check if your parameters are valid before running any numbers. It calculates the total cost for a batch of packages and provides a clear breakdown of unit prices.
