print_plate_object · Kiln MCP: Risk & Policy

WHAT IT DOES

What print_plate_object does on Kiln

AI agents invoke print_plate_object 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 print_plate_object needs a policy

The name strongly implies sending a print job to a 3D printer (triggering an external physical operation), which falls under Execute. Given the server context of controlling 3D printers, misuse could waste materials, damage hardware, or cause fire hazards — justifying high severity. Confidence is moderate because the description is empty.

From the tool's definition Tool name 'print_plate_object' on a server described as 'AI agent control of 3D printers'; description is empty and uninformative.
