extrude · Inventor MCP: Risk & Policy

WHAT IT DOES

What extrude does on Inventor

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

WHY IT NEEDS A POLICY

Why extrude needs a policy

In Autodesk Inventor, 'extrude' is a modeling operation that creates a 3D solid feature from a 2D sketch profile. This constitutes creating/modifying 3D model data, which maps to the Write category.

From the tool's definition Tool name 'extrude' on a server for parametric 3D modeling in Autodesk Inventor; description is empty.

Verdict

extrude Rate-limited

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 Inventor, so you can run agents against it safely.

FAQ

Questions about extrude

What does the extrude tool do? +

extrude. It is categorised as a Write tool in the Inventor MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on extrude? +

Register the Inventor MCP server in PolicyLayer and add a rule for 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 Inventor. Nothing to install.

What risk level is extrude? +

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

Can I rate-limit extrude? +

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

Set action: deny in the PolicyLayer policy for 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 extrude? +

extrude is provided by the Inventor MCP server (neonglay/inventor-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
