WHAT IT DOES

What abode_set_mode does on Garza Home MCP

AI agents invoke abode_set_mode to trigger actions in Garza Home MCP. 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 abode_set_mode needs a policy

Setting an alarm mode on a home security system (e.g., arming/disarming, home/away/night modes) triggers an external physical security operation. This is not a simple data write — it directly affects the armed state of the security system, with significant real-world consequences if misused (e.g., disarming a security system leaves the home unprotected).

From the tool's definition "Set alarm mode" — actively changes the operational state of a home security/alarm system
