pine_compile · Tradingview MCP: Risk & Policy

WHAT IT DOES

What pine_compile does on Tradingview

AI agents invoke pine_compile to trigger actions in Tradingview. 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 pine_compile needs a policy

Compiling and adding Pine Script to a chart constitutes code execution with side effects that depend on the script's logic. While not destructive in the file-deletion sense, a malicious or incorrect Pine Script could manipulate charts, trigger alerts, execute trades via strategies, or consume resources. The blast radius is significant in a financial context where TradingView is used for trading decisions.

From the tool's definition Tool description states 'Compile / add the current Pine Script to the chart' — this compiles and executes arbitrary Pine Script code against a live charting application.
