sap_scroll · MCP SAP GUI Server MCP: Risk & Policy

WHAT IT DOES

What sap_scroll does on MCP SAP GUI Server

AI agents invoke sap_scroll to trigger actions in MCP SAP GUI 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 sap_scroll needs a policy

Scrolling is a browser/GUI action that manipulates the state of an external SAP GUI session. While scrolling itself doesn't modify data, it is an Execute-category action because it drives an external application's UI.

From the tool's definition 'Scroll the SAP GUI screen' — triggers a UI interaction (scrolling) within the SAP GUI application, which is an external system operation that changes the viewport state
