Einkaufsbelege: Eingangsrechnungen, Bestellungen, Wareneingänge. Filter nach Zeitraum und Lieferant.
AI agents call einkaufbeleg_list to retrieve information from MonKey Office MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves accounting data (purchase receipts/documents) without creating, modifying, or deleting any records. It is a read-only retrieval operation consistent with other data-fetching tools on the server like buchung_list and debitor_list. The low blast radius reflects that misuse would only expose existing data, not alter business records or financial state.
From the tool's definition einkaufbeleg_list retrieves purchase documents (invoices, orders, goods receipts) with optional filtering by period and supplier.
