List accounts with optional type filter. Returns account names, balances, and types.
AI agents call firefly_list_accounts to retrieve information from Firefly III 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 information (names, balances, types) without creating, modifying, or deleting data. It is a Read operation. Severity is medium rather than low because the returned data includes account balances, which are sensitive financial information that could inform decisions about subsequent financial transactions or expose the user's financial state to an AI agent.
From the tool's definition Tool name 'firefly_list_accounts' and description 'List accounts with optional type filter. Returns account names, balances, and types' indicate retrieval of financial data without modification.
