Get file attachments (check images, receipts, etc.) for a QBO entity
AI agents call qbo_get_attachments to retrieve information from Kaizen Qbo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing file attachments from QuickBooks Online entities without creating, modifying, or deleting data. While the operation itself is read-only and non-destructive, the severity is elevated to 'medium' because the retrieved data (financial receipts, check images) could be sensitive and an agent with broad access could leak confidential financial information.
From the tool's definition Tool name contains 'get' and description states 'Get file attachments', which is a retrieval operation with no modification capability. The attachments retrieved (check images, receipts) are sensitive financial documents.
