What force_print_oversize does on Kiln
AI agents invoke force_print_oversize 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 force_print_oversize is rated High
The name suggests forcing a print job to proceed despite being oversized, which could override safety limits on a 3D printer and potentially cause physical damage or failed prints. In the context of 3D printer control (OctoPrint, Moonraker, Bambu, Prusa, Elegoo), forcing an oversized print could damage hardware or waste materials. Classified as Execute due to triggering an external physical operation.

The rule that runs force_print_oversize 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 force_print_oversize, this is the rule to start with:
force_print_oversize 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Kiln, apply this rule, and every force_print_oversize call is checked against it from then on.
Questions about force_print_oversize
force_print_oversize is a execute tool on the Kiln MCP server. It is categorised as a Execute tool in the Kiln MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Kiln MCP server in PolicyLayer and add a rule for force_print_oversize: 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.
force_print_oversize is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the force_print_oversize 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.
Set action: deny in the PolicyLayer policy for force_print_oversize. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
force_print_oversize is provided by the Kiln MCP server (codeofaxel/Kiln). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
