WHAT IT DOES

What scroll_screen does on Mcp Windows

AI agents invoke scroll_screen to trigger actions in Mcp Windows. 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.

RISK

Why scroll_screen is rated High

Scrolling the screen is a browser/UI interaction that executes an input event on the live Windows system. It has side effects (changes viewport, may trigger content loading or actions in focused applications) and falls under the Execute category as it performs an external operation on the system. Misuse could scroll through sensitive content or trigger unintended UI interactions.

From the tool's definition 'Scroll the screen in specified direction' — triggers a UI/input action on the Windows system

RECOMMENDED RULE

The rule that runs scroll_screen safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Windows, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For scroll_screen, this is the rule to start with:

scroll_screen Rate-limited

scroll_screen 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.

}

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Windows, apply this rule, and every scroll_screen call is checked against it from then on.
