Three.js DevTools MCP

Overview

Three.js DevTools MCP is a Model Context Protocol (MCP) server: Inspect and edit Three.js scenes, materials, shaders, lights in real time from any AI agent. In practice that means any MCP-compatible AI assistant can call Three.js DevTools MCP's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the npm package threejs-devtools-mcp speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.2.1, published under the MIT license, with source at DmitriyGolub/threejs-devtools-mcp on GitHub, where it has earned 88 stars.

Three.js DevTools MCP is listed under AI & Agents on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
