Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "assistant-widget": {
      "command": "npx",
      "args": [
        "-y",
        "@three-ws/assistant-mcp"
      ],
      "env": {
        "THREE_WS_BASE": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add assistant-widget --env THREE_WS_BASE=your-value -- npx -y @three-ws/assistant-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "assistant-widget": {
      "command": "npx",
      "args": [
        "-y",
        "@three-ws/assistant-mcp"
      ],
      "env": {
        "THREE_WS_BASE": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "assistant-widget": {
      "type": "stdio",
      "command": "npx",
      "args": [

      ],
      "env": {
        "THREE_WS_BASE": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is three.ws Assistant Widget 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 (0.1.2) reached the registry 26 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/assistant-mcp

Generate a paste-ready three.ws assistant widget, a floating 3D avatar chatbot for any website, from any AI agent.

A Model Context Protocol server that lets any AI assistant build a paste-ready embed for the three.ws assistant widget over stdio. Describe how you want the assistant to look and behave and build_assistant_widget returns a ready-to-paste tag, a standalone frame URL for embedding, and an equivalent ThreeAssistant.init({...}) JavaScript-API snippet, a floating 3D avatar chatbot that lives in the corner of any site. list_assistant_options enumerates every built-in avatar, background preset, interaction mode, chat lane, and data-* attribute you can set.

Both tools are pure and offline: building an embed is deterministic string logic over local validators. Every field is validated and clamped, so a bad or hostile value falls back to a safe default and the generated HTML is always well-formed. No API key, no signer, no payment, no network call. Point THREE_WS_BASE at a deployment (or leave the default) and go.

Install

npm install @three-ws/assistant-mcp

Or run with npx (no install):

npx -y @three-ws/assistant-mcp

Quick start

Claude Code, one line:

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

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

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

Inspect the surface with the MCP Inspector:

npx -y @modelcontextprotocol/inspector npx @three-ws/assistant-mcp

Tools

Tool	Type	What it does
`build_assistant_widget`	read-only	A config → a paste-ready embed (non-default settings as `data-*`), a frame URL, a `ThreeAssistant.init()` snippet, and the normalized config.
`list_assistant_options`	read-only	Enumerate every built-in avatar, background preset and grammar, interaction mode, chat lane, and the full `data-*` attribute reference.

build_assistant_widget is a pure function: the same config always yields the same embed, and it never touches the network. The generated tag carries only the settings that differ from their defaults, so a minimal config yields a minimal tag. The frame_url carries every resolved value (including defaults) so the standalone frame renders deterministically when dropped into an .

Input parameters

`build_assistant_widget`, all optional:

Field	Type / values	Default
`avatar`	avatar id, `/avatars/*.glb` path, or GLB URL	mannequin
`agent`	a three.ws agent id (alternative to `avatar`)	(none)
`background`	`transparent` \	`#hex` \	`ember`/`ocean`/`violet`/`forest`/`dusk`/`slate` \	`gradient:#a,#b[,angle]`	`transparent`
`mode`	`chat` \	`speak` \	`both`	`both`
`name`	string (≤ 60)	(none)
`greeting`	string (≤ 200)	(none)
`context`	string (≤ 500), what the assistant should know about the site	(none)
`accent`	`#hex`	`#f97316`
`position`	`right` \	`left`	`right`
`voice`	boolean, start with voice on/off	on
`badge`	boolean, show the three.ws attribution badge	on

Any value that fails validation (a bad hex, an unknown background, an over-long string) falls back to its default rather than being rejected, so you always get a working embed.

`list_assistant_options`, filter (optional: avatars \| backgrounds \| modes \| chat_lanes \| attributes). Omit to get everything.

Example

// build_assistant_widget

{

"avatar": "/avatars/selfie-girl.glb", "background": "ocean", "mode": "both", "name": "Aria", "greeting": "Hi! Ask me anything about the site.", "accent": "#00c2ff", "position": "left" } { "ok": true, "snippet": " ", "frame_url": "https://three.ws/assistant-frame?avatar=%2Favatars%2Fselfie-girl.glb&bg=ocean&mode=both&name=Aria&greeting=Hi%21+Ask+me+anything+about+the+site.&accent=%2300c2ff", "js_api": "ThreeAssistant.init({\n \"bg\": \"ocean\",\n \"mode\": \"both\",\n \"accent\": \"#00c2ff\",\n \"position\": \"left\",\n \"avatar\": \"/avatars/selfie-girl.glb\",\n \"name\": \"Aria\",\n \"greeting\": \"Hi! Ask me anything about the site.\"\n});", "builder_url": "https://three.ws/assistant", "config": { "bg": "ocean", "mode": "both", "accent": "#00c2ff", "position": "left", "avatar": "/avatars/selfie-girl.glb", "name": "Aria", "greeting": "Hi! Ask me anything about the site." }, "notes": "Chat runs on the free three.ws LLM chain by default (no key). Visitors can paste their own Groq or OpenRouter key in the widget settings for a private lane; that key stays in their browser." }

Paste the snippet before on any page, or drop the frame_url into an . Design it visually first at three.ws/assistant.

Requirements

Node.js >= 20.
No network access needed. THREE_WS_BASE only sets the origin baked into the generated URLs.

Environment variables

Variable	Required	Default
`THREE_WS_BASE`	no	`https://three.ws`

Programmatic use

The package entry point exports `TOOLS` (every tool definition: name, title, description, inputSchema, annotations, handler) and `buildServer()`, which returns a fully-registered McpServer with no transport attached. Both tools are pure and offline, so you can call them directly as a widget-builder library with no MCP client involved.

// run from a checkout: node this-file.mjs

import { TOOLS, buildServer } from '@three-ws/assistant-mcp';

const build = TOOLS.find((t) => t.name === 'build_assistant_widget'); const { snippet } = await build.handler({ avatar: '/avatars/michelle.glb', background: 'dusk' }); console.log(snippet);

// Or hand the whole registered server to your own MCP transport. buildServer();

<script src="https://three.ws/assistant/v1.js" async data-avatar="/avatars/michelle.glb" data-bg="dusk"></script>
