AI agents call account_info to retrieve information from MetaTrader 5 MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only query that returns account state without side effects. However, severity is elevated from 'low' to 'medium' because the returned data (balance, equity, margin, leverage) is financially sensitive. If an AI agent misuses this information to inform trading decisions on sibling tools like place_market_order or place_risk_order, the blast radius could be financial loss.
From the tool's definition Tool retrieves account information: login, currency, balance, equity, margin, free margin, leverage. No modifications, deletions, or transactions occur. Description explicitly uses 'Get' without write, execute, or destructive operations.
