Get detailed metadata about the current symbol (name, exchange, type, description)
AI agents call symbol_info 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 retrieves and queries metadata about a trading symbol. It performs no modifications, deletions, or external operations—it only reads and returns information. This is a typical Read category tool with minimal risk if misused by an AI agent, as it cannot alter state or cause financial transactions.
