WHAT IT DOES

What computer_double_click does on LocalAnt

AI agents invoke computer_double_click to trigger actions in LocalAnt. 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.

RISK

Why computer_double_click is rated High

This tool performs a UI interaction (double-click) at arbitrary screen coordinates, triggering whatever action is bound to that location on the user's PC. An AI agent could double-click executables, buttons, or links with unpredictable and potentially severe side effects depending on what is on screen.

RECOMMENDED RULE

The rule that runs computer_double_click safely

PolicyLayer is an MCP gateway: it sits between your AI agents and LocalAnt, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For computer_double_click, this is the rule to start with:

computer_double_click Rate-limited

computer_double_click stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
