sap_click · MCP SAP GUI Server MCP: Risk & Policy

WHAT IT DOES

What sap_click does on MCP SAP GUI Server

AI agents invoke sap_click 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.
