Reseller True-Profit & Fee Calculator MCP

Calculates true net profit and breakeven prices for resellers across eBay, Etsy, Poshmark, Mercari, Depop, Whatnot, and TikTok Shop. It itemizes fees from 2026 schedules, compares platforms by net profit, and determines minimum list prices to hit target profits.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http reseller-true-profit-fee-calculator-mcp https://reseller-fees-mcp.mcpize.run/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add reseller-true-profit-fee-calculator-mcp --url https://reseller-fees-mcp.mcpize.run/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable reseller-true-profit-fee-calculator-mcp in your MCP settings.
Cursor configuration
{
  "mcpServers": {
    "reseller-true-profit-fee-calculator-mcp": {
      "url": "https://reseller-fees-mcp.mcpize.run/mcp"
