adb_swipe · LocalAnt MCP: Risk & Policy

WHAT IT DOES

What adb_swipe does on LocalAnt

AI agents invoke adb_swipe to trigger actions in LocalAnt. 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 adb_swipe needs a policy

This tool executes a UI interaction (swipe gesture) on an Android device through ADB. It is an external operation that causes real device input, placing it in the Execute category. Misuse could trigger unintended navigation, dismiss dialogs, or interact with sensitive UI elements, but its blast radius is moderate since it is limited to gesture input on the connected device.

From the tool's definition 'Swipe between coordinates' — triggers a physical touch/gesture action on a connected Android device via ADB

Verdict

adb_swipe Rate-limited

adb_swipe 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.
