adb_swipe · ADB MCP Server MCP: Risk & Policy

WHAT IT DOES

What adb_swipe does on ADB MCP Server

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

This tool executes a UI interaction (swipe gesture) on a connected Android device. It is an 'Execute' category action because it triggers an external operation (device input simulation) whose effects depend on arguments — swiping different coordinates can scroll, dismiss, navigate, or interact with any on-screen element.

From the tool's definition Swipe from (x1,y1) to (x2,y2) with optional duration (ms) — triggers a physical touch/swipe gesture on the Android device screen via ADB input simulation
