What multi_copy_print does on Kiln
AI agents invoke multi_copy_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 multi_copy_print is rated High
Based on the server context (3D printer control) and the tool name, this tool likely triggers a multi-copy print job on a physical 3D printer. Executing a print job is an external physical operation that consumes materials (filament/resin), occupies the printer for extended periods, and can cause hardware damage if misused. The empty description lowers confidence.
From the tool's definition Tool name 'multi_copy_print' on a server described as 'AI agent control of 3D printers'; description is empty and uninformative.
Attacks that exploit this kind of access
The rule that runs multi_copy_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 multi_copy_print, this is the rule to start with:
multi_copy_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.
The button opens the PolicyLayer dashboard: create your workspace, connect Kiln, apply this rule, and every multi_copy_print call is checked against it from then on.
Questions about multi_copy_print
multi_copy_print 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 multi_copy_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.
multi_copy_print 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 multi_copy_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.
Set action: deny in the PolicyLayer policy for multi_copy_print. 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.
multi_copy_print 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.
