replay_autoplay · TradingView MCP: Risk & Policy

WHAT IT DOES

What replay_autoplay does on TradingView MCP

AI agents invoke replay_autoplay to trigger actions in TradingView MCP. 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 executes a UI action (toggling autoplay and setting speed) in TradingView via CDP. While primarily an Execute-class action, the warning about permanently corrupting cloud account state elevates severity. However, it doesn't irreversibly delete data in the traditional sense — it corrupts configuration state.

From the tool's definition 'Toggle autoplay in replay mode' and WARNING: 'Invalid values permanently corrupt your TradingView cloud account autoplay state'

replay_autoplay Rate-limited

replay_autoplay 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.
