WHAT IT DOES

What ui_click does on AirMCP

AI agents invoke ui_click to trigger actions in AirMCP. 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 ui_click is rated High

This tool triggers real UI interactions on the user's screen by simulating mouse clicks. It can activate any on-screen control, button, menu item, or link — effects depend entirely on what is clicked. An AI agent could misuse this to confirm dialogs, trigger destructive actions, submit forms, or navigate to sensitive areas, making it a high-severity Execute-category tool.

From the tool's definition "Click a UI element either by exact screen coordinates (x, y) or by searching for an element containing the given text"

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs ui_click safely

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

ui_click Rate-limited

ui_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.

The button opens the PolicyLayer dashboard: create your workspace, connect AirMCP, apply this rule, and every ui_click call is checked against it from then on.
