double_tap · Enhanced ADB MCP Server MCP: Risk & Policy

WHAT IT DOES

What double_tap does on Enhanced ADB MCP Server

AI agents invoke double_tap 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 double_tap needs a policy

This tool executes a physical UI gesture (double tap) on a connected Android device at specified coordinates. It triggers external operations whose effects depend on arguments (the coordinates determine what UI element is activated). Effects vary widely based on what is tapped — could open apps, confirm dialogs, delete items, etc.

From the tool's definition Double tap at coordinates — triggers a UI interaction on the Android device via ADB
