scroll_up · Enhanced ADB MCP Server MCP: Risk & Policy

WHAT IT DOES

What scroll_up does on Enhanced ADB MCP Server

AI agents invoke scroll_up 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 scroll_up needs a policy

This tool executes a physical UI gesture (scroll) on an Android device through ADB. It's not merely reading data, nor is it writing/modifying stored data — it performs an external operation (input event) whose effect depends on the current screen state. Misuse risk is low since scrolling is non-destructive and reversible in practice.

From the tool's definition 'Scroll up on the current screen' — triggers a UI interaction/browser-like action on an Android device via ADB

scroll_up Rate-limited

scroll_up 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.
