WHAT IT DOES

What computer_double_click does on Computer Use MCP Server

AI agents invoke computer_double_click to trigger actions in Computer Use MCP 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 computer_double_click needs a policy

Double-clicking executes UI actions whose effects depend entirely on the target element: it could open files, launch programs, confirm dialogs, or trigger arbitrary application logic. This is an Execute-category action with high severity because an AI agent could misuse it to interact with any on-screen element, potentially causing wide-ranging unintended effects on the live desktop environment.

From the tool's definition Double-click at the given coordinates — triggers UI interactions on a live desktop, activating buttons, opening files, or launching applications depending on what is at those coordinates
