WHAT IT DOES

What products_reserve_inventory does on MCP Dynamics 365 Commerce Server

AI agents use products_reserve_inventory 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 IT NEEDS A POLICY

Why products_reserve_inventory needs a policy

Reserving inventory creates a hold or allocation against available stock, which is a reversible write operation (reservations can typically be released). However, it has high severity because misuse by an AI agent could incorrectly reduce available inventory across the system, blocking legitimate orders, causing stockouts, or disrupting fulfillment operations at scale across a Dynamics 365 Commerce environment.

From the tool's definition 'Reserve product inventory' — reserving inventory modifies stock availability/allocation state in the system
