> A [Model Context Protocol](https://modelcontextprotocol.io) server that exposes **Loom**, the three.ws community 3D-creation gallery, over stdio. Browse what others have forged, pull any creation with a ready-to-embed viewer URL, and contribute your own GLB to the public feed.
Loom closes the loop with the rest of the three.ws 3D suite: forge a model with [`@three-ws/avatar-agent`](https://www.npmjs.com/package/@three-ws/avatar-agent) or compose a world with [`@three-ws/scene-mcp`](https://www.npmjs.com/package/@three-ws/scene-mcp), then **publish it here** for the whole platform to see. Every read is live and public; submitting needs no key or account — it is gated server-side only by an IP rate limit.
## Install
```bash
npm install @three-ws/loom-mcp
```
Or run with `npx` (no install):
```bash
npx @three-ws/loom-mcp
```
## Quick start
**Claude Code**, one line:
```bash
claude mcp add loom -- npx -y @three-ws/loom-mcp
```
**Claude Desktop / Cursor** (`claude_desktop_config.json` or `mcp.json`):
```json
{
"mcpServers": {
"loom": {
"command": "npx",
"args": ["-y", "@three-ws/loom-mcp"]
}
}
}
```
Inspect the surface with the MCP Inspector:
```bash
npx -y @modelcontextprotocol/inspector npx @three-ws/loom-mcp
```
## Tools
| Tool | Type | What it does |
| ----------------- | --------- | ----------------------------------------------------------------------------------------------------------------- |
| `get_loom_feed` | read-only | Browse the public gallery of community-forged 3D creations, newest-first, paginated via a `nextBefore` cursor. |
| `get_creation` | read-only | Fetch one creation by id, with its full metadata and an inline-previewable viewer URL + iframe. |
| `submit_creation` | write | Contribute a forged GLB to the public gallery. No key required; rate-limited (~20/hour per IP). |
Each read returns the creation's `glbUrl` plus a `viewer_url` (the `/forge/embed` orbit + AR viewer), an `og_image_url` (social card), and a paste-ready `iframe_snippet`, so any MCP client can preview the model inline.
### Input parameters
**`get_loom_feed`** — `limit` (1–120, default 60), `before` (ms-epoch cursor; pass the prior page's `nextBefore` to page backwards).
**`get_creation`** — `id` (required — the creation UUID).
**`submit_creation`** — `prompt` (required, ≤1000 chars), `glbUrl` (required — see allowed hosts below), `author` (optional attribution, ≤40 chars, defaults to `anon`), `previewImageUrl`, `tier`, `backend` (all optional).
## Submitting a creation
`submit_creation` posts to the **public, world-readable** gallery — only submit models you intend to share. There is **no account, key, or signer**: the endpoint is open and gated server-side by an IP rate limit (~20 submissions/hour) plus strict input sanitization. `author` is **free-text attribution, not an authenticated identity**.
The `glbUrl` must be an **https** URL hosted on one of these domains (enforced both client-side here and server-side):
`three.ws` · `r2.dev` · `cloudflarestorage.com` · `replicate.delivery` · `githubusercontent.com`
Re-submitting the exact same `glbUrl` returns the existing creation instead of duplicating it.
## Example
```jsonc
// submit_creation
> {
"prompt": "a glowing crystal totem, low-poly",
"glbUrl": "https://three.ws/demo/crystal.glb",
"author": "nova",
"backend": "hunyuan"
}
{
"ok": true,
"creation": {
"id": "f295398e-2d25-410d-a82f-c8725295a1b3",
"prompt": "a glowing crystal totem, low-poly",
"glbUrl": "https://three.ws/demo/crystal.glb",
"author": "nova",
"createdAt": 1750000000000,
"viewer_url": "https://three.ws/forge/embed?src=https%3A%2F%2Fthree.ws%2Fdemo%2Fcrystal.glb&title=a+glowing+crystal+totem%2C+low-poly",
"og_image_url": "https://three.ws/api/avatar-og?src=https%3A%2F%2Fthree.ws%2Fdemo%2Fcrystal.glb",
"iframe_snippet": "<iframe src=\"https://three.ws/forge/embed?src=…\" width=\"640\" height=\"360\" …></iframe>"
}
}
```
```jsonc
// get_loom_feed
> { "limit": 2 }
{ "ok": true, "count": 2, "nextBefore": 1749999000000, "has_more": true,
"creations": [ { "id": "…", "prompt": "…", "glbUrl": "…", "viewer_url": "…", "iframe_snippet": "…" } ] }
```
Drop a creation's `iframe_snippet` onto any web page, or open its `viewer_url` to orbit the model (with AR on supported devices).
## Requirements
- **Node.js >= 20.**
- Network access to `https://three.ws` (or your own `THREE_WS_BASE`).
### Environment variables
| Variable | Required | Default |
| --------------------- | -------- | ------------------ |
| `THREE_WS_BASE` | no | `https://three.ws` |
| `THREE_WS_TIMEOUT_MS` | no | `20000` |
No API key, signer, or account is needed for any tool.
