## Why ui_fullscreen is rated High

This tool executes a UI action (toggling fullscreen mode) in an external application via Chrome DevTools Protocol. It's not a read operation, nor does it create/modify persistent data, delete anything, or involve finances. It triggers an external operation (UI automation), placing it in the Execute category. The blast radius is low as it only affects the display state of the TradingView window.

From the tool's own definition: "Toggle TradingView fullscreen mode — triggers a UI state change in TradingView Desktop via Chrome DevTools Protocol"

## Use case

AI agents invoke ui_fullscreen to trigger actions in TradingView MCP Server. 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.
