AI agents call quickfile_invoice_get to retrieve information from QuickFile MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query operation to fetch invoice data. The mention of sanitization of user-controlled fields in the response indicates data retrieval only, with no side effects or ability to modify financial records. It falls squarely within the Read category. Severity is low because unauthorized invoice retrieval carries minimal risk compared to financial transaction execution or data destruction.
