## MCP tools (6)

### `generate_3d_model` (~172 tokens)

Generate a 3D model from text

Turn a text prompt into a textured, downloadable 3D model (GLB). Free and keyless. Describe a SINGLE object, character, or creature: "a brass mid-century desk lamp", not a whole scene. Returns the model URL plus links that open it in the viewer, in the user's room through their phone camera, and in the AR studio. Use kind:"avatar" for a character: it comes back rigged, so it idles and animates instead of standing in a T-pose.

Input parameters:

- `kind` (string): model (a prop, default), avatar (a rigged character), or mesh (art-directed, prompt refined first).
- `prompt` (string, required): The single object or character to model.
- `tier` (string): Detail level. Higher is slower.

### `check_generation` (~68 tokens)

Collect a generation that was still rendering

Collect a 3D generation that was still rendering when generate_3d_model returned. Pass the job_id from that result. While it is still working you get updated timing; when it is done you get the model.

Input parameters:

- `job_id` (string, required): The job_id from a pending generation.

### `search_models` (~120 tokens)

Search the ready-made model library

Search the ready-made 3D model catalogue by name, category and tag. The default catalogue is a few hundred public-domain (CC0) props, free to use commercially. Faster and more predictable than generating when a common object will do: search first, generate what you cannot find.

Input parameters:

- `catalogue` (string): A different catalogue URL to search instead of the default.
- `limit` (integer): How many results to return. Default 12.
- `query` (string): Words to match against names, categories and tags. Omit to browse.

### `compose_ar_scene` (~163 tokens)

Arrange models into one AR scene and get a link

Arrange several models into a single scene and get one link that reopens it exactly: same models, same positions, rotations and scales. Open that link on a phone and the whole arrangement stands in the real room. Coordinates are metres on the floor: x is right, z is forward with negative values further away, so { x: 0, z: -2 } is two metres in front of the viewer. This is the tool to reach for when someone wants to see more than one thing at once.

Input parameters:

- `models` (array, required): The models to arrange, in placement order.
- `page_url` (string): The page hosting the studio. Defaults to the hosted demo.
- `title` (string): A name for the scene, used in the summary.

### `export_ar` (~156 tokens)

Turn a model into a "View in your space" link

Turn any public GLB URL into a one-tap "View in your space" experience. The returned link routes itself by device: Apple Quick Look on iPhone and iPad, Google Scene Viewer on Android, an interactive WebGL viewer on desktop. Use it right after generating or finding a model so the person can put it on their actual desk.

Input parameters:

- `glb_url` (string, required): Public https URL of a .glb or .gltf model.
- `kind` (string): avatar marks a rigged character, which stays animated.
- `title` (string): Name shown in the AR experience.
- `user_agent` (string): If you know the viewer's User-Agent, the response names the viewer they will get.

### `create_ar_page` (~167 tokens)

Generate a deployable AR page

Return a complete, self-contained HTML page that embeds the AR studio, configured for the caller's models. Write it to a file, commit it, and it works on GitHub Pages, Netlify, Vercel, or any static host: no build step and no API key. Use it when someone asks to "add AR to my site" rather than just to see a model.

Input parameters:

- `accent` (string): Accent colour, any CSS colour.
- `assets` (string): Catalogue URL for the model tray. Defaults to the free CC0 library.
- `generate` (boolean): Show the text-to-3D prompt box. Default true.
- `models` (array): Models pre-loaded into the scene on open.
- `title` (string): Page and studio title.
