Three.js Scene MCP

What it does

Three.js Scene MCP gives Claude four tools to assemble and render interactive 3D scenes using the PMNDRS god stack (Three.js + RAPIER physics + OrbitControls). The server generates complete, renderable scene code that feeds directly into the Three.js 3D Viewer MCP tool, enabling a seamless text-to-3D pipeline inside Claude.

It takes care of all the boilerplate — physics world setup, camera controls, renderer config — so Claude only needs to describe what objects to include.

Key features

• One-shot scene assembly — wraps any scene snippet with full RAPIER + OrbitControls boilerplate ready to render
• Named scene templates — instantly load pre-built environments: physics_sandbox, character_stage, arena, space
• Object spawning — generate individual shape + physics + material snippets to compose into larger scenes
• Material palettes — retrieve ready-to-use material collections for consistent visual styling
• Blueprint editor UI — an included HTML app for visual blueprint editing
