profitlee-mcp
An MCP server for Profitlee — compute country-accurate Amazon FBA/FBM and TikTok Shop profit margins, and manage saved scenarios, from any MCP client (Claude Desktop, Claude Code, Cursor, …).
calculate_profit is free and needs no token. The scenario tools require a Profitlee Pro API token.
MCP registry name:
io.github.AronLEEdev/profitlee-mcp
Quick start
Add to your MCP client config:
{
"mcpServers": {
"profitlee": {
"command": "npx",
"args": ["-y", "profitlee-mcp"],
"env": {
"PROFITLEE_API_TOKEN": "eck_live_xxx"
}
}
}
}
PROFITLEE_API_TOKEN is optional — omit the whole env block to use calculate_profit only. Create a token on your Profitlee account page to unlock the scenario tools.
Requires Node.js 20+.
Tools
calculate_profit inputs
Pick a platform + mode, give the product's physical and cost details, and Profitlee folds every fee into a single net margin. Rates are 0–1 decimals (e.g. 0.15 = 15%). US uses inches + pounds; DE/JP use cm + kg.
The Profitlee API is the source of truth for validation — incomplete or out-of-range inputs come back as a clear error listing the offending fields. Full field reference: https://profitlee.com/docs/api.
Environment variables
How it works
The server is a thin wrapper over Profitlee's public HTTP API:
calculate_profit→POST /api/v1/calculate(public, no token).- scenario tools →
/api/v1/scenarios*(require the Pro token; the server fails fast with a clear message if it's missing).
No fee logic is reimplemented here, so results always match the live Profitlee calculator and current fee tables.
