Nyaomaru 3D MCP UI

What it does

Nyaomaru 3D MCP UI is a lightweight TypeScript MCP server that bridges the Nyaomaru 3D web app into any MCP-compatible AI client. It registers a ui:// resource and an open-nyaomaru-3d-ui tool so the AI can trigger the 3D scene to render inline — turning a standard chat interface into an interactive 3D viewer.

Key features

• Registers ui://nyaomaru-3d/mcp-app.html as an MCP UI resource for in-client rendering
• Single tool open-nyaomaru-3d-ui triggers the 3D scene on demand
• Runs locally on http://localhost:3001/mcp with zero config
• Tunnel-ready via ngrok for remote AI client access (e.g. ChatGPT)

Installation

Setup (local server)

pnpm dev
