Overview

R3 is a Model Context Protocol (MCP) server: Build interactive 3D web apps — scenes, physics, audio and music — from composable components. Because it speaks the Model Context Protocol, AI assistants can use R3 as a set of callable tools instead of you copy-pasting between apps.

It's a hosted (remote) server — point your client at https://mcp.r3js.org/mcp and you're connected, with nothing to install locally. The current release is v1.2.0.

On mcp.site, R3 sits in the Development category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below. If you maintain R3 for r3js.org, claim this listing to verify ownership, earn the Verified badge, and keep the details current.
