translate_stl · MCP 3D Printer Server MCP: Risk & Policy

WHAT IT DOES

What translate_stl does on MCP 3D Printer Server

AI agents use translate_stl to create or update resources in MCP 3D Printer Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP 3D Printer Server environment.

WHY IT NEEDS A POLICY

Why translate_stl needs a policy

This tool modifies the position/geometry of an STL file by translating it along axes. This is a reversible modification (the file can be moved back), so it falls under Write rather than Destructive. Misuse could corrupt or unintentionally alter 3D model files, hence medium severity.

Verdict

translate_stl Rate-limited

translate_stl stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches MCP 3D Printer Server, so you can run agents against it safely.

FAQ

Questions about translate_stl

What does the translate_stl tool do? +

Move an STL model along specific axes. It is categorised as a Write tool in the MCP 3D Printer Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on translate_stl? +

Register the MCP 3D Printer Server MCP server in PolicyLayer and add a rule for translate_stl: 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 MCP 3D Printer Server. Nothing to install.

What risk level is translate_stl? +

translate_stl is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit translate_stl? +

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

Set action: deny in the PolicyLayer policy for translate_stl. 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 translate_stl? +

translate_stl is provided by the MCP 3D Printer Server MCP server (mcpflow/dmontgomery40_mcp-3d-printer-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
