# rhino_surface_from_points Create a NURBS surface from a 2D grid of control points. Agent View of the PolicyLayer registry record for `rhino_surface_from_points`. HTML page: https://policylayer.com/tools/easehee-rhino-mcp/rhino-surface-from-points ## Facts - Tool: `rhino_surface_from_points` - 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_surface_from_points", "arguments": {} } } ``` ## Why rhino_surface_from_points is rated Medium This tool creates new geometry objects (NURBS surfaces) in Rhino, which is a reversible write operation. It does not execute arbitrary code, delete data, or move money. The severity is medium because misuse could create unwanted geometry that clutters the model, but the operation is reversible through undo or deletion. The confidence is high because the description clearly indicates a creation/write action. From the tool's own definition: "Tool description states it will 'Create a NURBS surface' — a direct creation operation that modifies the Rhino geometry model." ## Use case AI agents use rhino_surface_from_points 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**.
