## Description

You shouldn't have to double-check every line item on a purchase order. This MCP gives your AI client the mathematical precision needed to manage supplier order finances. Instead of guessing at totals, your agent can use this tool to pull together exact figures for every transaction. 

You can use it to find the initial cost of goods before any adjustments are made. If a supplier offers a seasonal promotion or a bulk rate, the tool applies those specific rules to the total. It also handles tax calculations, including the ability to use a global tax rate for consistency.
