layout_switch

THE RISK

High Risk

This tool triggers an external operation in the TradingView Desktop application — switching the active chart layout. It doesn't merely read data or write/create a record; it executes a UI/application state change via Chrome DevTools Protocol. Misuse could disrupt a user's active workflow or analysis session, though it is reversible by switching back.

HOW TO CONTROL LAYOUT_SWITCH

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 layout_switch:

policy.json

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

layout_switch 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.
