Search for symbols by name or keyword
AI agents call symbol_search 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 performs a search query to find symbols matching user criteria. It retrieves information from TradingView's symbol database without creating, modifying, deleting, or executing any operations. The search capability has minimal blast radius—worst case, an AI agent could search for unexpected symbols, but this causes no harm to data or systems.
From the tool's definition Tool name 'symbol_search' and description 'Search for symbols by name or keyword' indicate a query operation that retrieves data without modification or side effects.
