## What it does

This server connects coding agents directly to the public three.ws 3D repository. The `get_loom_feed` tool retrieves recent creations using cursor pagination, while `get_creation` fetches individual asset metadata via UUID. Returned entries supply direct GLB download paths, social preview cards, and drop-in iframe markup for inline previews.

Sharing generated assets relies on `submit_creation`. Submissions require neither an account nor an authorization key. However, the remote endpoint enforces an IP limit of roughly 20 submissions per hour. The submitted `glbUrl` must use HTTPS and sit on allowed hosts like `three.ws`, `r2.dev`, `cloudflarestorage.com`, `replicate.delivery`, or `githubusercontent.com`.

The server requires Node.js 20 or higher. Without network access to `https://three.ws`, every query will fail.

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

## Install

## When to use it
- inspect recent community 3D assets in GLB format
- retrieve ready-to-use iframe markup for 3D model previews
- fetch complete metadata and viewer links for a specific model UUID
- publish generated GLB models directly to the three.ws public feed

## Example prompts
- Show me the newest 10 3D models from the three.ws feed.
- Fetch details and an iframe snippet for model id "f295398e-2d25-410d-a82f-c8725295a1b3".
- Submit "https://three.ws/accessories/hat-cowboy.glb" to three.ws with prompt "low-poly cowboy hat" and author "nova".
