ui_mouse_click

THE RISK

High Risk

This tool performs browser/UI automation by simulating mouse clicks at arbitrary coordinates within TradingView. It triggers external operations (UI interactions) whose effects depend on where the click lands — it could activate trades, change settings, or trigger other workflows. This falls under Execute as it performs actions with context-dependent side effects.

HOW TO CONTROL UI_MOUSE_CLICK

PolicyLayer is an MCP gateway — it sits between your AI agents and TradingView MCP Bridge, and nothing reaches the server without passing your rules. This is the rule we recommend for ui_mouse_click:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ui_mouse_click": {
      "limits": [
        {
          "counter": "ui_mouse_click_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

ui_mouse_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.

Create a free account and register TradingView MCP Bridge — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
