submit_provider_job · Kiln MCP: Risk & Policy

WHAT IT DOES

What submit_provider_job does on Kiln

AI agents invoke submit_provider_job 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 submit_provider_job needs a policy

In the context of a 3D printer control server, 'submit_provider_job' most likely submits a print job to a printer or external service, which constitutes triggering an external operation (Execute). The blast radius is high because initiating a print job on industrial or consumer 3D printers can consume materials, time, and potentially cause physical damage if misconfigured.

From the tool's definition Tool name 'submit_provider_job' implies triggering an external operation (submitting a job to a provider/printer). Description is empty and uninformative, lowering confidence.
