splice_mesh_at_z · Kiln MCP: Risk & Policy

WHAT IT DOES

What splice_mesh_at_z does on Kiln

AI agents invoke splice_mesh_at_z 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 splice_mesh_at_z needs a policy

The name suggests a mesh modification operation — cutting or splitting a 3D mesh at a given Z coordinate. This is likely a Write or Execute operation that modifies geometry. Given the context of a 3D printer control server with mesh manipulation siblings (add_mesh_chamfer, add_mesh_fillet), this is most likely a destructive-ish mesh transformation. However, with an empty description, confidence is low.

From the tool's definition Tool name 'splice_mesh_at_z' and empty description. Inferred from name: modifies a 3D mesh by splicing/cutting at a Z-plane level.

Verdict

splice_mesh_at_z Rate-limited

splice_mesh_at_z 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.

FAQ

Questions about splice_mesh_at_z

What does the splice_mesh_at_z tool do? +

splice_mesh_at_z. 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.

How do I enforce a policy on splice_mesh_at_z? +

Register the Kiln MCP server in PolicyLayer and add a rule for splice_mesh_at_z: 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 splice_mesh_at_z? +

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

Can I rate-limit splice_mesh_at_z? +

Yes. Add a rate_limit block to the splice_mesh_at_z 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 splice_mesh_at_z completely? +

Set action: deny in the PolicyLayer policy for splice_mesh_at_z. 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.

What MCP server provides splice_mesh_at_z? +

splice_mesh_at_z 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.
