WHAT IT DOES

What pause_print does on Kiln

AI agents invoke pause_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.

RISK

Why pause_print is rated High

Pausing a 3D print triggers an external physical operation on real hardware. While the description is empty (lowering confidence), the tool name and server context strongly indicate this sends a command to halt an active print job on a 3D printer. This is an Execute-category action — it triggers an external operation whose effects depend on the current state of the printer.

From the tool's definition Tool name 'pause_print' on a server described as 'AI agent control of 3D printers' with tools for OctoPrint, Moonraker, Bambu, Prusa, Elegoo

RECOMMENDED RULE

The rule that runs pause_print safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Kiln, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For pause_print, this is the rule to start with:

pause_print Rate-limited

pause_print stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

How do I enforce a policy on pause_print? +

Register the Kiln MCP server in PolicyLayer and add a rule for pause_print: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Kiln. Nothing to install.

What risk level is pause_print? +

pause_print is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit pause_print? +

Yes. Add a rate_limit block to the pause_print rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block pause_print completely? +
