## Why approve_supplier_invoices is rated Medium

This tool modifies the status of supplier invoices from pending to approved, which is a write operation on financial data. While invoices are financial in nature, the operation itself is approval/status modification rather than payment execution or money movement, making it Write rather than Financial. However, approving invoices can trigger downstream financial obligations (payment processing), so severity is high.

From the tool's own definition: "Tool name is 'approve_supplier_invoices' and description states it 'Approve multiple supplier invoices at once.' Approval is a reversible state change to financial records."

## Use case

AI agents use approve_supplier_invoices to create or update resources in Tripletex MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tripletex MCP Server environment.
