rotate_extrude · 3D MCP Server MCP: Risk & Policy

WHAT IT DOES

What rotate_extrude does on 3D MCP Server

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

WHY IT NEEDS A POLICY

Why rotate_extrude needs a policy

This tool creates/generates new 3D model data by extruding a 2D profile rotationally. It is a constructive/write operation with no destructive, financial, or execution implications. Misuse has minimal blast radius as it only affects in-session 3D model state.

From the tool's definition 'Create a solid of revolution by rotating a 2D profile around the Z axis' — creates new 3D geometry

Verdict

rotate_extrude Rate-limited

rotate_extrude 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 3D MCP Server, so you can run agents against it safely.

FAQ

Questions about rotate_extrude

What does the rotate_extrude tool do? +

Create a solid of revolution by rotating a 2D profile around the Z axis. It is categorised as a Write tool in the 3D MCP 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 rotate_extrude? +

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

What risk level is rotate_extrude? +

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

Can I rate-limit rotate_extrude? +

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

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

rotate_extrude is provided by the 3D MCP Server MCP server (jagjerez-org/3d-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
