WHAT IT DOES

What cart_add_charge does on MCP Dynamics 365 Commerce Server

AI agents use cart_add_charge to create or update resources in MCP Dynamics 365 Commerce Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Dynamics 365 Commerce Server environment.

RISK

Why cart_add_charge is rated Medium

Adding a charge to a cart is a write operation that modifies cart state. It is reversible (charges can typically be removed), so it's Write rather than Destructive. While it involves financial amounts, it does not move money or commit financial obligations — it only stages a charge in a cart prior to checkout, so Financial does not apply. Misuse could lead to incorrect charges being applied to customer orders.

From the tool's definition 'Add charge to cart' — creates/modifies cart data by adding a financial charge entry
