android_tap_resource · DevLab MCP Suite MCP: Risk & Policy

WHAT IT DOES

What android_tap_resource does on DevLab MCP Suite

AI agents invoke android_tap_resource to trigger actions in DevLab MCP Suite. 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 android_tap_resource needs a policy

Tapping a UI element triggers an external operation on the Android device whose effects depend on which element is tapped. This is an Execute-category action (browser/device interaction), as it simulates user input that can trigger arbitrary app behaviors. Severity is medium because the impact depends on what UI element is tapped — it could dismiss dialogs, submit forms, or trigger significant in-app actions.

From the tool's definition 'Shortcut for tapping a node by resource-id' — performs a tap action on a UI element of an Android device
