Moltline Shipping Maths is a remote MCP server that gives an AI agent 6 tools, among them dim_weight, free_shipping_threshold, freight_class. It answers at https://mcp.moltlinestudio.com/shipping over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.
Dimensional weight, parcel fit, landed cost and freight class. 4 of 6 tools free.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
dim_weight | Work out whether a parcel bills on its size or its weight. FREE. Carriers charge the greater of actual weight and dimensional weight, so a light bulky box costs more than the scale suggests. Typical input {"length": 18, "width": 12, "height Inputs: length, width, height, actual_weight, divisor, custom_divisor |
free_shipping_threshold | Find the order value at which free shipping stops costing you money. PREMIUM (license). Break-even is where the gross margin on the order covers the shipping you absorb. Typical input {"gross_margin_pct": 45, "ship_cost": 7.5, "current_aov" Inputs: gross_margin_pct, ship_cost, current_aov, target_uplift_pct |
freight_class | Derive a US LTL freight class from density. FREE. Density in pounds per cubic foot maps to a class on the published NMFC density scale. Typical input {"length": 48, "width": 40, "height": 36, "weight": 400} returns {"cubic_feet": 40.0, "den Inputs: length, width, height, weight, units |
landed_cost | Total what a unit really costs once freight, duty and fees are in. FREE. Duty is applied to goods value, tax to goods plus duty plus freight — the common import treatment — and the order is spelled out in the response so you can check it ag Inputs: unit_cost, quantity, freight_total, duty_pct, tax_pct, other_fees |
parcel_fit | Pick the smallest box an item actually fits in, allowing for padding. FREE. Tries every rotation of the item against every box, so an item that only fits diagonally-oriented is still found. Typical input {"item_length": 10, "item_width": 6, Inputs: item_length, item_width, item_height, box_options, padding |
rate_card | Turn a cost model into a customer-facing weight-banded price table. PREMIUM (license). Prices each band at its upper bound so you never under-charge inside a band, then rounds up to a tidy increment. Typical input {"base_cost": 4.2, "cost_p Inputs: base_cost, cost_per_lb, bands_lb, margin_pct, round_to |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.moltlinestudio.com/shipping. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
