export_scene · Sketchup MCP: Risk & Policy

WHAT IT DOES

What export_scene does on SketchupMCP

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

WHY IT NEEDS A POLICY

Why export_scene needs a policy

Exporting a scene creates a new output file containing scene data. This is a write operation—it generates/exports data but does not delete, modify, or destroy existing SketchUp data. The operation is reversible (the export file can be deleted without affecting the original scene).

From the tool's definition Tool name 'export_scene' and description 'Export the current scene' indicate creation/writing of scene data to an external file format without irreversible data loss.

Verdict

export_scene Rate-limited

export_scene 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.

Export the current scene. It is categorised as a Write tool in the SketchupMCP 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_scene? +

Register the Sketchup MCP server in PolicyLayer and add a rule for export_scene: 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 SketchupMCP. Nothing to install.

What risk level is export_scene? +

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

Can I rate-limit export_scene? +

Yes. Add a rate_limit block to the export_scene 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_scene completely? +

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

export_scene is provided by the Sketchup MCP server (piexl/sketchup-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
