WHAT IT DOES

What layout_switch does on TradingView MCP Bridge

AI agents invoke layout_switch to trigger actions in TradingView MCP Bridge. 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 layout_switch is rated High

Switching layouts triggers an external operation in the TradingView desktop app via Chrome DevTools Protocol, changing the application's active state. It's not a simple read, nor does it destructively delete data, but it executes an action in the external app that modifies the visible/active context. Effects depend on the specified layout argument.

RECOMMENDED RULE

The rule that runs layout_switch safely

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

layout_switch Rate-limited

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.
