## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "tab_switch",
    "arguments": {}
  }
}
```

## 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 own definition: "Switch to a chart tab by index — triggers a UI navigation action in the TradingView Desktop app via Chrome DevTools Protocol"

## Use case

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.
