run_quick_print · Kiln MCP: Risk & Policy

WHAT IT DOES

What run_quick_print does on Kiln

AI agents invoke run_quick_print 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 run_quick_print needs a policy

This tool triggers an external operation (3D printer execution) whose effects depend on arguments (print file, settings, hardware state). The impact is not reversible mid-print without manual intervention. While not destructive in the data-deletion sense, a misconfigured or malicious print job could damage hardware, waste materials, or create safety hazards.

From the tool's definition Tool name 'run_quick_print' combined with server context (3D printer control) indicates execution of a print job. Description is empty, limiting specificity.
