### Description (declared)

# openusd-mcp

An MCP server that lets AI assistants read, inspect, and manipulate [OpenUSD](https://openusd.org) scenes.

**[Live Demo](https://daslabhq.github.io/openusd-mcp/)** — interactive 3D viewer with variant switching

```
pip install openusd-mcp
```

## What it does

Connect this MCP server to Claude, ChatGPT, Cursor, or any MCP-compatible client. Your AI assistant can then work directly with `.usda`, `.usdc`, and `.usdz` files — inspecting scene graphs, querying properties, exporting meshes, and switching variants.

## Tools

| Tool | Description |
|------|-------------|
| `usd_inspect` | Read the scene graph — list all prims, types, hierarchy |
| `usd_get_prim` | Get detailed properties, attributes, and metadata for a specific prim |
| `usd_get_materials` | List all materials and their shader parameters |
| `usd_get_transforms` | Get world-space transforms for prims |
| `usd_list_variants` | List all variant sets and their options |
| `usd_set_variant` | Switch a variant selection |
| `usd_export_mesh` | Export a mesh prim as STL or OBJ |
| `usd_scene_stats` | Get scene statistics — prim count, mesh count, material count, bounding box |

## Quick start

### With Claude Desktop

Add to your `claude_desktop_config.json`:

```json
{
  "mcpServers": {
    "openusd": {
      "command": "openusd-mcp",
      "args": []
    }
  }
}
```

Then try it with the included example scenes:

*"Inspect the scene graph of examples/desk_setup.usda and describe what's on the desk."*

*"What color options does the product in examples/product_configurator.usda have? Switch it to gold."*

### With any MCP client

```bash
openusd-mcp --stdio
```

The server communicates over stdin/stdout using the [MCP protocol](https://modelcontextprotocol.io).

## Examples

The repo includes two example scenes that exercise all 8 tools.

### Desk setup — scene inspection

A desk with a table, monitor, keyboard, and mug. 5 PBR materials (wood, metal, screen, ceramic, dark plastic), 10 meshes, …
