# 3D AR Studio

Turns 3D models into an augmented-reality scene in the browser and hands back one link that opens it in someone's room.

## What it does

The MCP server gives an agent three moves: generate a model from a text prompt, arrange several models into a scene, and return a single link that opens that scene in a phone camera. Models, positions, rotations and scales travel inside the URL, so you can compose on a laptop and show it on a phone.

It runs through `npx -y 3d-ar-studio-mcp`. With no environment variables it falls back to the public three.ws model set and a keyless generator. Point `AR_STUDIO_ASSETS` at your own catalogue to swap the tray, and set `AR_STUDIO_PAGE_URL` to the page the scene should live on. `AR_STUDIO_ORIGIN` decides which domain the link belongs to — leave it out and the shared link points somewhere other than your site.

The server ships as its own binary in a separate package, so `npx 3d-ar-studio-mcp` resolves on its own while the `3d-ar-studio` package installs separately. iPhones have no WebXR, so there the scene goes to Apple AR Quick Look, converted to USDZ on the device.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `AR_STUDIO_PAGE_URL`, `AR_STUDIO_ASSETS`, `AR_STUDIO_MCP_ENDPOINT`, `AR_STUDIO_ORIGIN` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

### Claude Code (native platform)

**Platform CLI**
```bash
claude mcp add --env AR_STUDIO_PAGE_URL=<AR_STUDIO_PAGE_URL> --env AR_STUDIO_ASSETS=<AR_STUDIO_ASSETS> --env AR_STUDIO_MCP_ENDPOINT=<AR_STUDIO_MCP_ENDPOINT> --env AR_STUDIO_ORIGIN=<AR_STUDIO_ORIGIN> --transport stdio 3d-ar-studio -- npx -y 3d-ar-studio-mcp
```
Replace <…> with your own values

### Codex

**Platform CLI**
```bash
codex mcp add 3d-ar-studio --env AR_STUDIO_PAGE_URL=<AR_STUDIO_PAGE_URL> --env AR_STUDIO_ASSETS=<AR_STUDIO_ASSETS> --env AR_STUDIO_MCP_ENDPOINT=<AR_STUDIO_MCP_ENDPOINT> --env AR_STUDIO_ORIGIN=<AR_STUDIO_ORIGIN> -- npx -y 3d-ar-studio-mcp
```
Replace <…> with your own values

### Cursor

            "args": [
                "-y",
                "3d-ar-studio-mcp"
            ],
            "env": {
                "AR_STUDIO_PAGE_URL": "<AR_STUDIO_PAGE_URL>",
                "AR_STUDIO_ASSETS": "<AR_STUDIO_ASSETS>",
                "AR_STUDIO_MCP_ENDPOINT": "<AR_STUDIO_MCP_ENDPOINT>",
                "AR_STUDIO_ORIGIN": "<AR_STUDIO_ORIGIN>"
            }
        }
    }
}
```

### GitHub Copilot

**Config file**
File `.vscode/mcp.json`:

                "AR_STUDIO_ORIGIN": "<AR_STUDIO_ORIGIN>"
            }
        }
    }
}
```

## When to use it
- assemble an AR scene from several GLB models and share it as one link
- generate a 3D model from a text prompt and drop it into the room
- swap the default model tray for your own catalogue
- check how a scene looks on a phone without building an app
- show a client furniture placement inside their actual space

## Example prompts
- Generate a floor lamp model and place it next to the sofa in the scene
- Build an AR scene from `chair.glb` and `table.glb` and give me the link
- Load my model catalogue from `AR_STUDIO_ASSETS` and list what's in it
