pine_check · TradingView MCP Jackson MCP: Risk & Policy

WHAT IT DOES

What pine_check does on TradingView MCP Jackson

AI agents invoke pine_check to trigger actions in TradingView MCP Jackson. 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_check needs a policy

Compiling Pine Script requires executing code through TradingView's compiler. While it may not directly modify chart state, it triggers an external operation (compilation) via CDP, which qualifies as Execute. Misuse could involve injecting malicious Pine Script for compilation or probing TradingView internals.

From the tool's definition 'Compile Pine Script via TradingView' — compiling code is an execution operation that runs/processes scripts through TradingView's compiler engine via Chrome DevTools Protocol
