Ldraw MCP

Give your MCP client eyes for LEGO® models. Render LDraw files (.ldr / .mpd / .dat) to images with _real part geometry_ - studs, slopes, window glass - using headless Blender and the ImportLDraw addon. The output looks like a BrickLink Stud.io render, with no GUI anywhere in the loop. It runs locally over stdio via the published package.

People who work with 3d rendering, blender and ldraw and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Ldraw MCP

Claude Code

claude mcp add musharna-ldraw-mcp -- uvx ldraw-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "musharna-ldraw-mcp": {
      "command": "uvx",
      "args": [
        "ldraw-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
