## Why replay_step is rated High

This tool executes an action within the TradingView Desktop application (advancing the chart replay by one bar). It triggers an external operation via CDP, making it Execute category. The blast radius is low as it only affects chart state/view in replay mode with no data modification or financial transactions.

From the tool's own definition: "'Advance one bar in replay mode' — triggers an external operation in TradingView Desktop via Chrome DevTools Protocol"

## Use case

AI agents invoke replay_step 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.

## Recommended policy (PolicyLayer)
