force_print_oversize · Kiln MCP: Risk & Policy

WHAT IT DOES

What force_print_oversize does on Kiln

AI agents invoke force_print_oversize to trigger actions in Kiln. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why force_print_oversize needs a policy

The name suggests forcing a print job to proceed despite being oversized, which could override safety limits on a 3D printer and potentially cause physical damage or failed prints. In the context of 3D printer control (OctoPrint, Moonraker, Bambu, Prusa, Elegoo), forcing an oversized print could damage hardware or waste materials. Classified as Execute due to triggering an external physical operation.
