Overview

Ecom Calc is an MCP server that performs financial calculations tailored for e-commerce, including profit margins, pricing strategies, break-even analysis, shipping costs, inventory turnover, ROI, and sales tax. It processes input data like costs, revenues, and volumes to output actionable metrics via API calls.
