WHAT IT DOES

What cart_override_charge does on MCP Dynamics 365 Commerce Server

AI agents use cart_override_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_override_charge is rated Medium

This tool modifies the charge amount on a cart item, which is a write operation that alters pricing data. While it affects financial values, it does not directly move money or commit financial obligations — it modifies a cart record which is reversible. However, misuse could allow an AI agent to set charges to zero or arbitrary values, bypassing intended pricing, making severity high.

From the tool's definition 'Override charge amount' — modifies a financial charge on a cart, but is a reversible write operation (the cart can be updated again)
