Open a saved Pine Script by name
AI agents call pine_open to retrieve information from TradingView MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool opens/retrieves an existing saved Pine Script by name. It reads/loads existing data without modifying or executing anything. The action is essentially a file-open/read operation on a saved script, making it a Read category. Low severity as it only accesses already-saved scripts and has minimal blast radius if misused.
