export_model · OpenSCAD MCP Server MCP: Risk & Policy

WHAT IT DOES

What export_model does on OpenSCAD MCP Server

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

WHY IT NEEDS A POLICY

Why export_model needs a policy

Export operations create or materialize new data artifacts (files in specified formats) based on existing models. This is reversible and non-destructive—the original model remains unchanged, and the exported file can be deleted or overwritten. No code execution, deletion, or financial transaction occurs.

From the tool's definition The tool 'export_model' is described as exporting a 3D model to a specific format. The word 'export' indicates data transformation and output generation.

Verdict

export_model Rate-limited

export_model 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.

FAQ

Questions about export_model

What does the export_model tool do? +

Export a 3D model to a specific format. It is categorised as a Write tool in the OpenSCAD 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 export_model? +

Register the OpenSCAD MCP Server MCP server in PolicyLayer and add a rule for export_model: 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 OpenSCAD MCP Server. Nothing to install.

What risk level is export_model? +

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

Can I rate-limit export_model? +

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

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

export_model is provided by the OpenSCAD MCP Server MCP server (jhacksman/openscad-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
