export · 3D MCP Server MCP: Risk & Policy

WHAT IT DOES

What export does on 3D MCP Server

AI agents use export 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 export needs a policy

Export operations write data to new files, making this a Write category tool. Severity is low because exporting 3D models to standard formats has minimal blast radius — it creates output artifacts but doesn't modify existing data, delete resources, execute arbitrary commands, or involve financial transactions. An AI agent misusing this tool would at worst create unwanted export files, which is easily recoverable.

From the tool's definition Tool description states 'Export the scene to STL, OBJ, 3MF, AMF, or other formats' — this creates/outputs new files in specified formats. The action writes data to storage without destructing existing models or executing arbitrary code.

Verdict

export Rate-limited

export 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 export

What does the export tool do? +

Export the scene to STL, OBJ, 3MF, AMF, or other formats (requires OpenSCAD). 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 export? +

Register the 3D MCP Server MCP server in PolicyLayer and add a rule for export: 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 export? +

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

Can I rate-limit export? +

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

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

export 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.
