scroll_down · Enhanced ADB MCP Server MCP: Risk & Policy

WHAT IT DOES

What scroll_down does on Enhanced ADB MCP Server

AI agents invoke scroll_down 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_down needs a policy

This tool triggers a physical UI interaction (scroll gesture) on an Android device via ADB. It executes an action on the device rather than reading data or writing/modifying persistent state. The blast radius is low since scrolling is a benign, reversible UI gesture with minimal risk of harm.

scroll_down Rate-limited

scroll_down 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.
