Use DimGenius in ChatGPT and Claude

Plan freight loads from a chat. Paste a packing list or a customer’s quote email, and your assistant uses the DimGenius load calculator to work out how many trucks you need and which trailers fit — then you can tweak items in plain English and recalculate.

Claude Code and other MCP clients

DimGenius is a remote MCP server (Streamable HTTP) with OAuth sign-in. In Claude Code:

claude mcp add --transport http dimgenius https://www.dimgenius.com/api/mcp

Other clients: add a remote MCP server with the connector URL; the client discovers sign-in automatically.

What it can do

  • Calculate loadout
    Works out how many trucks a shipment needs and which trailers fit it, and saves it to My Shipments.
  • Extract freight items
    Pulls item rows (dimensions, weight, quantity) out of pasted text such as an email, quote, or packing list.
  • Edit / recalculate shipment
    Changes rows in a saved shipment — weight, dimensions, quantity, stackable, full width — or its options, and recalculates.
  • List saved shipments / Get shipment
    Finds past shipments and shows their items and results.
  • List trailers
    Shows the trailer types available to you, including your custom trailers.
  • Create / update / delete custom trailer
    Manages the custom trailers on your account or organization.

Every calculation is saved to My Shipments, where you can open it in the calculator and view the load diagrams.

Things to try

  • “Run this through DimGenius: 6 crates 96x48x60 at 2,500 lbs each and a generator 144x78x84 at 9,800 lbs.”
  • “Here’s the quote email from the customer — what trucks do we need for it?”
  • “Make the crates stackable and change the generator to 700 lbs, full width.”
  • “Try the same shipment enclosed only.”
  • “Show my last 5 shipments.”
  • “Add a custom trailer: 53 ft flatbed, 102 in wide, 48,000 lbs capacity.”

Questions

Can ChatGPT or Claude calculate a freight load plan?
Yes, with the DimGenius connector. The assistant sends your items to the DimGenius load calculator, which works out how many trucks the freight needs and which trailer types fit it — flatbeds, stepdecks, RGNs, double drops, hotshots, dry vans, box trucks, and Sprinter vans — including stacking and over-dimensional freight.
Do I need a DimGenius account?
Yes. You sign in with your DimGenius account (Google or email) when you connect. Calculations run on your account, follow its plan, and are saved to My Shipments just like calculations in the web app.
What can the assistant see?
Only what it sends to DimGenius tools: the items and options for a calculation, or the text you ask it to extract freight from. DimGenius never receives your other conversations.
How do I disconnect?
Remove or disconnect DimGenius in your assistant’s connector settings. Access tokens expire after an hour and are no longer refreshed once you disconnect.
Which apps work?
Claude (web, desktop, and mobile), ChatGPT, Claude Code, and any other client that supports remote MCP servers with OAuth.
