Open a saved Pine Script by name
AI agents call pine_open to retrieve information from TradingView MCP Bridge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Opening a saved Pine Script is primarily a read/retrieval action: it fetches a stored script and displays it. It does not modify data, execute code, or have destructive effects. The severity is low because the worst case is loading an unintended script into the editor, which is easily reversible.
From the tool's definition 'Open a saved Pine Script by name' — retrieves/opens an existing saved script
