replay_autoplay · TradingView MCP Bridge MCP: Risk & Policy

WHAT IT DOES

What replay_autoplay does on TradingView MCP Bridge

AI agents invoke replay_autoplay 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.

WHY IT NEEDS A POLICY

Why replay_autoplay needs a policy

This tool triggers an external operation (toggling autoplay and controlling playback speed) within TradingView's replay mode. It doesn't merely read data or write/modify stored data, but actively controls chart playback behavior — an execution-type action with side effects on the application state. Misuse could disrupt analysis workflows but has limited blast radius.
