What cart_resume does on MCP Dynamics 365 Commerce Server
AI agents use cart_resume 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.
Why cart_resume is rated Medium
This tool modifies cart data by changing its status from suspended to resumed. This is a write operation (not merely reading data) and is reversible (the cart can be suspended again). While it affects commerce operations, it does not permanently delete data, execute arbitrary code, or move money, so it is categorized as Write rather than a more severe category.
From the tool's definition Tool name 'cart_resume' and description 'Resume suspended cart' indicate modification of cart state from suspended to active/resumed, which is a reversible write operation on commerce data.
Attacks that exploit this kind of access
The rule that runs cart_resume safely
PolicyLayer is an MCP gateway: it sits between your AI agents and MCP Dynamics 365 Commerce Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For cart_resume, this is the rule to start with:
cart_resume stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect MCP Dynamics 365 Commerce Server, apply this rule, and every cart_resume call is checked against it from then on.
