WHAT IT DOES

What cart_search does on MCP Dynamics 365 Commerce Server

AI agents call cart_search to retrieve information from MCP Dynamics 365 Commerce Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why cart_search is rated Low

The tool performs a search/query operation to retrieve cart information based on specified criteria. This is a non-destructive read operation with no side effects. Even in a commerce system context, searching carts only retrieves existing data without creating, modifying, or deleting anything. Blast radius is minimal—worst case is information disclosure of cart data.

From the tool's definition Tool name 'cart_search' and description 'Search carts by criteria' indicate a query operation that retrieves cart data without modifying state.

RECOMMENDED RULE

The rule that runs cart_search safely

cart_search Allowed

cart_search is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
