WHAT IT DOES

What cart_checkout does on MCP Dynamics 365 Commerce Server

AI agents use cart_checkout to commit financial operations through MCP Dynamics 365 Commerce Server, usually the final step of a payment, billing, or trading workflow. A call moves real money.

RISK

Why cart_checkout is rated Critical

Checking out a cart in an e-commerce system like Dynamics 365 Commerce finalizes a purchase, committing financial obligations (payment processing, order creation). This is the most severe category applicable as it directly involves financial transactions. Misuse could result in unauthorized purchases or financial commitments.

From the tool's definition 'cart_checkout' - 'Checkout the cart' commits a financial transaction by converting a cart into a sales order with payment obligations
