WHAT IT DOES

What click_at does on Mcp Control Plane

AI agents invoke click_at to trigger actions in Mcp Control Plane. 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 click_at is rated High

This tool performs UI automation by moving the cursor and clicking at arbitrary screen coordinates. It can trigger any on-screen action — launching applications, clicking buttons, submitting forms — making it an Execute-class tool. Misuse could result in unintended system actions with wide blast radius, especially in a control plane context with access to Windows and other systems.

From the tool's definition Move to screen coordinates, click, and optionally return to the original cursor position.

RECOMMENDED RULE

The rule that runs click_at safely

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

click_at Rate-limited

click_at 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.
