## Description

You can stop manually calculating tax line items or checking regional rates. This MCP gives your AI client the ability to handle precise financial math. When you need to know the final price of an item after tax, your agent uses the tools here to find the exact tax amount and the resulting gross price. If you are managing a large list of products, you can process them all in one go. It also helps you stay accurate by letting your agent check if a specific tax rate is valid for a region or by pulling the current tax tiers available in a specific area. Every calculation is rounded to two decimal places, so you don't have to worry about rounding errors in your financial data.
