## Description

You can stop manually calculating retail math. This MCP gives your AI agent the specific tools needed to manage grocery promotions and customer totals. Instead of guessing if a subtotal hits a certain threshold, your agent uses the validation tool to confirm eligibility. It handles the heavy lifting of subtracting discount amounts from subtotals and generating clear summaries of what was saved versus what was spent. Whether you are building a retail assistant or just need a quick way to check receipt math, this MCP provides the precision required for financial accuracy in a grocery context.
