confirm_print_recovery · Kiln MCP: Risk & Policy

WHAT IT DOES

What confirm_print_recovery does on Kiln

AI agents invoke confirm_print_recovery 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 confirm_print_recovery needs a policy

This tool triggers execution of a recovery plan on a physical 3D printer. It initiates an external operation on hardware whose effects (resuming or altering a print job) are real-world and difficult to reverse. While not purely destructive, it executes a physical process that could damage prints, waste material, or harm the printer if the recovery plan is flawed.
