WHAT IT DOES

What ui_fullscreen does on TradingView MCP Bridge

AI agents invoke ui_fullscreen 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 ui_fullscreen is rated High

This tool executes a UI action (toggling fullscreen) in an external application. It doesn't read data, write/modify data persistently, or perform destructive/financial operations. It's an external UI interaction that fits the Execute category. Severity is low as toggling fullscreen has minimal blast radius.

From the tool's definition Toggle TradingView fullscreen mode — triggers an external UI operation in the TradingView Desktop app via Chrome DevTools Protocol

ui_fullscreen Rate-limited

ui_fullscreen 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.
