What symbol_search does on TradingView MCP Bridge
AI agents call symbol_search to retrieve information from TradingView MCP Bridge without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why symbol_search is rated Low
This is a read-only operation that searches and returns symbol information. It has no side effects, does not execute code or commands, does not modify data, and does not involve financial transactions. The low severity reflects minimal blast radius even if misused—an AI agent could only retrieve symbol metadata, which is non-destructive and typically public information in trading platforms.
From the tool's definition Tool name 'symbol_search' and description 'Search for symbols by name or keyword' indicate a query operation that retrieves symbol data without modifying any state or executing trades.
