drag_mouse · Computer Control Mcp Lands MCP: Risk & Policy

WHAT IT DOES

What drag_mouse does on Computer Control Mcp Lands

AI agents invoke drag_mouse to trigger actions in Computer Control Mcp Lands. 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 drag_mouse needs a policy

Drag mouse is a UI automation action that can interact with arbitrary UI elements — moving files, resizing windows, drawing, triggering drag-and-drop operations. This constitutes execution of external operations whose effects depend on arguments. The description is empty, lowering confidence slightly, but the server context and sibling tools strongly imply this is a mouse drag automation action.

From the tool's definition Tool name 'drag_mouse' on a server providing 'mouse and keyboard automation' and 'computer control capabilities'; sibling tools include click_screen, move_mouse, press_key, type_text.
