Short answer

How can I use AI to find the cheapest shipping?

Your AI uses the ShipEngine MCP to query multiple carriers for a specific package. It identifies the lowest cost option based on the weight and destination you provide. You'll see the specific carrier options and prices below.

The results you get

Where your data lands

The AI processes the carrier data and presents it in a way that makes sense for your decision.

COST

Lowest price found

The agent identifies the cheapest available rate among all queried carriers. You get a clear view of the minimum cost for your shipment.

SPEED

Delivery time options

The AI compares how fast different carriers can deliver your package. This lets you weigh the cost against the urgency of the shipment.

CARRIERS

You receive a list of the specific providers that can handle your package. This shows you exactly which companies are offering the rates.

FAQ

How this task behaves

  • 01

    Can the AI buy the shipping label for me?

    No. The AI only retrieves and compares rates. You must manually purchase the label through your carrier or shipping software.

  • 02

    Does the AI know my specific carrier discounts?

    The AI uses the rates available through the ShipEngine connection. It does not automatically apply private account discounts unless they are already set up in your ShipEngine account.

  • 03

    Can I ask for international shipping rates?

    Yes. Just provide the destination country and the package details in your prompt.

  • 04

    Can the AI change my shipping address in ShipEngine?

    No. The AI only has permission to read rate data. It cannot modify any of your account settings or saved addresses.

  • 05

    What if I don't know the package weight?

    The AI needs the weight to get an accurate quote. If you don't provide it, the agent will ask you for it before it can run the tool.
