Rupa3D MCP Server

local only

Rupa3D runs on your own machine — the client starts it, so there is no endpoint to ping. 193 installs a week from npm. Last commit 15 Sep 2026.

Checks GLB assets against a spec without Blender and embeds the measured proof inside the GLB.

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

  const jalur = (a.env && process.env[a.env]) || path.join(REPO, a.jalur);
      keluar = await this.#spawn([
Executes code built at runtime bpy/kerja.py:197, [пакет] bpy/kerja.py:197
    exec(compile(t["kode"], "<rupa_skrip>", "exec"), ruang_nama)
  el('pilih-isi').innerHTML = baris

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add rupa3d -- npx -y rupa3d
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "rupa3d": {
      "args": [
        "-y",
        "rupa3d"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.rupa3d]
command = "npx"
args = ["-y", "rupa3d"]
.cursor/mcp.json
{
  "mcpServers": {
    "rupa3d": {
      "args": [
        "-y",
        "rupa3d"
      ],
      "command": "npx"
    }
  }
}
.vscode/mcp.json

        "rupa3d"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: RUPA3D_BLENDER (Path to the Blender executable. Only the Blender-backed tools need it; GLB checking, CAD and scenes run without Blender.), RUPA3D_RUANG (Workspace directory for scenes and CAD shapes. Default: ~/.rupa3d). The author declared them in the registry entry; get the values from the project itself.

Rupa3D — questions

Answers built from our own checks of this server.

Why is there no uptime for Rupa3D?
Rupa3D runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package rupa3d was installed 193 times last week.
How do I connect Rupa3D?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It runs locally, so the command pulls rupa3d straight from npm; nothing to host, nothing to sign up for.
How many people use Rupa3D?
The npm package rupa3d was installed 193 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Rupa3D open source?
Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
