WHAT IT DOES

What reject_supplier_invoice does on Tripletex MCP Server

AI agents use reject_supplier_invoice 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.

RISK

Why reject_supplier_invoice is rated Medium

Rejecting a supplier invoice is a Write operation because it updates the invoice record's status and processing state. While the action affects financial workflows and accounting records, it is reversible—rejected invoices can typically be resubmitted or the rejection can be overturned by a human accountant.

From the tool's definition Tool name 'reject_supplier_invoice' and description 'Reject a supplier invoice' indicate the tool modifies the state of a supplier invoice (from pending/submitted to rejected status). This is a reversible state change, not a deletion.
