Common questions

Is three.ws Loom safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.3) reached the registry 27 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@three-ws/loom-mcp

Loom — the three.ws community 3D-creation gallery, from any AI agent. Browse the public feed of community-forged GLB creations, fetch one with its viewer URL, and submit your own.

A Model Context Protocol 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 or compose a world with @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

npm install @three-ws/loom-mcp

Or run with npx (no install):

npx @three-ws/loom-mcp

Quick start

Claude Code, one line:

claude mcp add loom -- npx -y @three-ws/loom-mcp

Claude Desktop / Cursor (claude_desktop_config.json or mcp.json):

"mcpServers": { "loom": { "command": "npx", "args": ["-y", "@three-ws/loom-mcp"] } } }

Inspect the surface with the MCP Inspector:

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. The dedupe is best-effort by design: it scans only the newest few entries, which is where an accidental re-POST lands. Re-submitting a GLB that has since scrolled down the feed creates a second record.

get_creation answers an id that no longer exists with a typed `not_found` error rather than an empty creation, so a stale id in a saved reference is unambiguous.

Example

// submit_creation

{

"prompt": "a cowboy hat, low-poly", "glbUrl": "https://three.ws/accessories/hat-cowboy.glb", "author": "nova", "backend": "hunyuan" } { "ok": true, "creation": { "id": "f295398e-2d25-410d-a82f-c8725295a1b3", "prompt": "a cowboy hat, low-poly", "glbUrl": "https://three.ws/accessories/hat-cowboy.glb", "author": "nova", "createdAt": 1750000000000, "viewer_url": "https://three.ws/forge/embed?src=https%3A%2F%2Fthree.ws%2Faccessories%2Fhat-cowboy.glb&title=a+cowboy+hat%2C+low-poly", "og_image_url": "https://three.ws/api/avatar-og?src=https%3A%2F%2Fthree.ws%2Faccessories%2Fhat-cowboy.glb", "iframe_snippet": " " } }

// 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).

Examples

Runnable examples live in examples/:

node examples/list-tools.mjs     # every tool with its full input schema

node examples/browse-loom.mjs # a page of the gallery + one creation's embed, live

Both spawn this server over stdio and read the live public gallery. They are deliberately read-only: submit_creation posts to a world-readable feed, so no example writes on your behalf. See examples/README.md for expected output.

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.
