Build 3D scenes, websites and app screens in Spline from your AI agent. The agent works in a live Spline editor, so what it builds is an editable Spline file, not generated code you have to maintain.
This repository is an agent plugin. It bundles:
- the Spline MCP server, hosted at
https://mcp.spline.design/mcp - a skill that teaches the agent how to work with it: when to use Spline, how to start, and the build–look–refine loop
Install Spline from the Cursor Marketplace (open Customize in the sidebar, find Spline, select Install).
/plugin marketplace add splinetool/spline-skills
/plugin install spline@spline
The first time the agent uses a Spline tool, your editor asks you to sign in to Spline in the browser and approve access. The agent then works in your Spline account.
The agent's work runs in Spline's cloud editor, so nothing has to be open. When it creates or opens a file, it gives you a link to the Spline editor: open it in your browser to watch the design come together and edit it yourself.
