press_home · Enhanced ADB MCP Server MCP: Risk & Policy

WHAT IT DOES

What press_home does on Enhanced ADB MCP Server

AI agents invoke press_home to trigger actions in Enhanced ADB MCP 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 press_home needs a policy

This tool triggers an external operation on the Android device (simulating a hardware button press), which navigates away from the current app. It is an action with side effects on the device state, fitting the Execute category. The blast radius is low as it only navigates to the home screen without deleting data or incurring financial consequences.

press_home Rate-limited

press_home stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
