margin_check
shallowcom.moltlinestudio/dropship · Verify this server
Show what one sale actually leaves after every cost. FREE. Subtracts supplier cost, shipping, payment fees, the ad spend that found the buyer, and anything else — then reports the break-even price so you know how much room there is. Typical input {"sell_price": 39.99, "supplier_cost": 12.4, "shipping_cost": 4.2, "ad_cost_per_order": 9} returns {"revenue": 39.99, "total_cost": 27.06, "profit": 12.93, "margin_pct": 32.33, "markup_pct": 222.5, "break_even_price": 27.06, "biggest_cost": "supplier_cost"}. Use before listing a product. Not for a whole tiered price list — that is price_ladder — and not for the effect of returns, which is returns_impact. Errors: on invalid, missing, or malformed input this tool never raises a protocol error — it returns {"error": "<what is wrong and how to fix it>"}. Every call is read-only and idempotent, so after correcting the input it is always safe to retry.
No longer in the registry. The MCP registry stopped listing this server as of 11 Sept 2026. This report card stays available because the measurement was real, but the tool is excluded from search, rankings, and Vouch’s corpus counts. A published behaviour score is never recomputed or removed — it reflects what was measured while the server was listed.
