AI agents call symbol_info to retrieve information from MetaTrader 5 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

The low severity reflects that misuse would only expose market data without enabling financial loss, unauthorized modifications, or destructive actions.
