Delete a company gateway. DELETE /gateways/{gatewayId}. Fails if gateway is linked to company currencies or customers.
AI agents call delete_gateway to permanently remove resources in Rebillia MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes a payment gateway configuration. While the deletion may fail if dependencies exist, the intent and capability are destructive in nature. The high severity reflects that deleting a gateway could disrupt billing operations and is not easily recoverable without reconfiguration. The tool represents infrastructure-level deletion that cannot be undone.
