ShopTrueProfit Fee & Profit MCP

13 tools for seller math

Connect the MCP endpoint to Claude, Cursor or any MCP client, or start batch runs with up to 1,000 calculations. Ask for fees, profit and margin, the break-even price, the price that reaches a target margin, or which marketplace leaves the most profit. Results include an itemized fee breakdown, the assumptions applied, the fee-table version and date, and links to the official fee pages. It uses the same fee engine as the free calculators on shoptrueprofit.com. Bad input is rejected with a clear message, never silently adjusted.

Pay only for calculations

Prices are set on the Apify Store. Runs and billing are handled by Apify under its terms and privacy policy; on the MCP (Standby) endpoint Apify also bills its platform usage.

Pure math, nothing stored

Calculations run inside the Actor from published fee schedules. There is no scraping, no marketplace login and no API key for Etsy, eBay or Amazon, and the inputs (prices, costs, dimensions, categories) are not stored. Batch results go to your own Apify dataset. Results are estimates; your marketplace statement is the final word.
