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
| Tool | Auth | Description |
|---|---|---|
calculate_profit | none | Full per-unit cost stack, gross/net margin, and monthly P&L. |
list_scenarios | Pro token | List your saved scenarios. |
get_scenario | Pro token | Read one scenario (inputs + outputs) by id. |
save_scenario | Pro token | Save a named scenario from calculator inputs. |
update_scenario | Pro token | Rename and/or replace a scenario's inputs. |
delete_scenario | Pro token | Delete a scenario by id. |
copy_scenario | Pro token | Duplicate a scenario into a new one ("Copy of …"). |
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.
| Field | Notes |
|---|---|
platform | amazon (default) or tiktok_shop. |
region | us, de, or jp. |
mode | amazon: fba | fbm. tiktok_shop: fbt | self_fulfilled. |
L, W, H, weight | Dimensions + unit weight. |
fob, headShip, duty | Unit cost, inbound freight/unit, import duty/unit. |
price | Selling price (gross; VAT-inclusive for DE/JP). |
ppcAcos, returnRate | Ad ACoS and return rate (0–1). |
monthlyVolume | Units/month (scales the P&L). |
referralPct | Referral fee (0–1). Preferred over referralCategory. |
isApparel | Affects some fees. |

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
| Var | Required | Default | Purpose |
|---|---|---|---|
PROFITLEE_API_TOKEN | No | — | Pro token (eck_live_…); needed only for the scenario tools. |
PROFITLEE_BASE_URL | No | https://profitlee.com | Override the API origin (testing). |
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.
