bytebot_scroll · ByteBot MCP Server MCP: Risk & Policy

WHAT IT DOES

What bytebot_scroll does on ByteBot MCP Server

AI agents invoke bytebot_scroll to trigger actions in ByteBot 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 bytebot_scroll needs a policy

Scrolling is a mouse/keyboard operation that controls the desktop UI. It has real side effects (navigating content, potentially triggering lazy-load, infinite scroll, or UI state changes) and is part of a broader desktop automation system. It's not purely read-only since it drives the UI, making Execute the appropriate category.

From the tool's definition 'Scroll the screen in a specific direction' and 'direct desktop computer control' — triggers a physical input action on the desktop
