WHAT IT DOES

What tab_switch does on TradingView MCP Bridge

AI agents invoke tab_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 tab_switch is rated High

This tool performs a browser/application UI action (switching tabs) rather than simply reading data or writing persistent data. It executes an external operation in the locally running TradingView app. Misuse could disrupt the user's workflow by switching away from their active chart, but has limited blast radius beyond UI disruption.

From the tool's definition Switch to a chart tab by index — triggers a UI navigation action in the TradingView Desktop app via Chrome DevTools Protocol

RECOMMENDED RULE

The rule that runs tab_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 tab_switch, this is the rule to start with:

tab_switch Rate-limited

tab_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.
