WHAT IT DOES

What light_bulb_off does on Dual MCP Server for IoT & Memory

AI agents invoke light_bulb_off to trigger actions in Dual MCP Server for IoT & Memory. 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 light_bulb_off needs a policy

This tool executes a command against a physical IoT device (a light bulb), causing a real-world state change. It is not purely a read, write to a data store, or financial operation. The action is reversible (the light can be turned back on), so it does not qualify as Destructive. Execute is the appropriate category.

From the tool's definition 'Turn the light bulb OFF' — triggers an external physical operation on an IoT device
