WHAT IT DOES

What shifts_use does on MCP Dynamics 365 Commerce Server

AI agents invoke shifts_use to trigger actions in MCP Dynamics 365 Commerce Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why shifts_use needs a policy

'Using' a shift in a retail/commerce context typically means activating or claiming an open shift, which triggers external operations in the POS/store system (e.g., associating a cashier with a register, enabling transaction processing). This is an action with real operational side effects rather than a simple read or reversible write.

From the tool's definition 'Use an existing shift' — activates or applies an existing shift record in Dynamics 365 Commerce
