## Description

You can use this MCP to handle the heavy lifting of commercial pricing math. Instead of manually calculating unit costs or converting weights, you just give the data to your AI client. It handles the math for you. If you need to know how much a single item costs within a bulk order, the tool finds that number instantly. If you are dealing with bulk goods, you can convert total prices into specific weight units like kilograms or grams without manual conversion steps. It also provides a high-level view of transaction economics, giving you a clear breakdown of the total cost, unit price, and quantity in one go. To keep things accurate, it includes a check to ensure the quantities you provide are valid for commercial use. This keeps your pricing analysis clean and prevents errors during the calculation process.
