rotate_screen · Enhanced ADB MCP Server MCP: Risk & Policy

WHAT IT DOES

What rotate_screen does on Enhanced ADB MCP Server

AI agents invoke rotate_screen 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 rotate_screen needs a policy

Rotating the screen is an external operation executed on a connected Android device via ADB. It modifies device state (orientation) in a way that affects the running UI and app behaviour. It is not a simple data read or write to a data store, and while it can be reversed, the act of triggering it constitutes an Execute-class operation.

From the tool's definition "Rotate screen orientation" — triggers a device-level UI/system operation via ADB that changes the physical display state

Verdict

rotate_screen Rate-limited

rotate_screen 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.
