WHAT IT DOES

What mouse_drag does on Mcp Serial Hid Kvm

WHY IT NEEDS A POLICY

Why mouse_drag needs a policy

This tool performs physical mouse drag actions on a real PC via KVM, triggering UI interactions (drag-and-drop, window resizing, text selection) whose effects depend entirely on the target application and arguments. It is an Execute-class action — it triggers external operations with context-dependent side effects.

From the tool's definition Drag from one position to another (press button at start, move to end, release). Useful for drag-and-drop, selecting text, resizing windows, etc.
