Get the current balance for a specific bank account. Returns available and current balance information.
AI agents call lunchflow_get_account_balance to retrieve information from Lunch Flow MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves account balance information with no side effects, placing it in the Read category. Severity is high (not critical) because while it accesses sensitive financial data that could inform fraud, identity theft, or account targeting, it does not itself move money, delete data, or execute transactions.
From the tool's definition Tool description states it 'Get[s] the current balance for a specific bank account' with 'Returns available and current balance information' — purely retrieves financial data without modification or transaction execution.
