# rhino_export_obj Export selected (or all) objects to a Wavefront OBJ file (mesh-only). Agent View of the PolicyLayer registry record for `rhino_export_obj`. HTML page: https://policylayer.com/tools/easehee-rhino-mcp/rhino-export-obj ## Facts - Tool: `rhino_export_obj` - Server: Rhino (`easehee/rhino-mcp`) — https://policylayer.com/tools/easehee-rhino-mcp.md - Homepage: https://github.com/EaseHee/rhino-mcp - Risk category: Write (Medium risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "rhino_export_obj", "arguments": {} } } ``` ## Why rhino_export_obj is rated Medium This tool creates a new file artifact (OBJ format export) from existing 3D model data. It is reversible (the exported file can be deleted or overwritten) and does not modify the source Rhino models or commit irreversible changes. File export operations are Write category rather than Execute because they have deterministic, predictable side effects (file creation) rather than arbitrary code execution. From the tool's own definition: "Tool description states 'Export selected (or all) objects to a Wavefront OBJ file', which creates/writes a new file output based on Rhino geometry data." ## Use case AI agents use rhino_export_obj to create or update resources in Rhino, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Rhino environment. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
