Connector

One URL. Your AI gets three.ws.

Add three.ws to Claude, ChatGPT, Cursor, VS Code or Claude Code and your assistant can generate 3D models and avatars, run your agents, read their wallets and pay for services over x402. Sign in once in your browser: there is no API key to copy. Every tool is listed in the MCP tool catalog.

Pick a server

Start with three.ws. Add others later; each is its own connector.

URL https://three.ws/api/mcp

Add it to your client

Links open your client with the server filled in. You still review it and confirm.

Works on claude.ai and the Claude desktop app, on every plan. Free accounts can add one custom connector. On Team and Enterprise, only owners can add one.

Open Claude with the URL filled in

Click the button above, check the name and URL, then click Add. Adding it by hand instead: Customize → Connectors (Settings → Connectors on some accounts), Add custom connector, paste the URL.
Click Connect and sign in to three.ws. Read the permissions before you approve.
In a chat, open the + menu, then Connectors, and switch three.ws on for that conversation.

Steps follow Claude's own guide. Its menus move: if these drift, tell us.

ChatGPT adds custom MCP servers through Developer mode, on the plans where OpenAI offers it. There is no pre-filled link, so copy the URL first.

In Settings → Apps & Connectors → Advanced settings, turn on Developer mode.
Back in Apps & Connectors, click Create. Name it three.ws, paste the URL, choose OAuth, and create it.
Sign in to three.ws when ChatGPT asks, and approve the permissions.
In a new chat, open the + menu, choose Developer mode, and tick three.ws.

Steps follow OpenAI's developer mode guide. Its labels change often: if these drift, tell us.

One command adds the server. The first time a tool needs your account, Claude Code opens three.ws sign-in in your browser.

Terminal

claude mcp add --transport http three-ws-main https://three.ws/api/mcp

Run the command. Add --scope project to share it with your team through .mcp.json.
In Claude Code, type /mcp, pick the server you just added and choose Authenticate.

The button opens Cursor's install prompt with the server filled in. Cursor then runs the three.ws sign-in.

Add to Cursor

Or add it to ~/.cursor/mcp.json

{
  "mcpServers": {
    "three-ws-main": { "url": "https://three.ws/api/mcp" }
  }
}

Link format from Cursor's install-link docs.

For GitHub Copilot agent mode in VS Code. The button opens VS Code's install prompt; the server signs you in on first use.

Add to VS Code VS Code Insiders

Or add it to .vscode/mcp.json

{
  "servers": {
    "three-ws-main": { "type": "http", "url": "https://three.ws/api/mcp" }
  }
}

Link format from VS Code's MCP developer guide.

Any client that speaks Streamable HTTP MCP can connect. Clients with OAuth support sign you in automatically from the server's WWW-Authenticate header. Clients without it can send an API key from Dashboard → API as Authorization: Bearer.

mcp.json

{
  "mcpServers": {
    "three-ws-main": { "type": "http", "url": "https://three.ws/api/mcp" }
  }
}

Every hosted server, with its auth and resources, is listed machine-readably at /.well-known/mcp.json.

Worth knowing

You never copy a key

Signing in gives your client its own token for your three.ws account, with the permissions you approved on the consent screen. Tools act on the agents and wallets of the account you sign in with.

Revoke it any time

Every client you connect appears under Dashboard → Settings → Connected apps. Revoking one stops that client within an hour, when its current access token expires. Your agents and balances are untouched.

Every tool is labelled

Each tool declares whether it only reads, writes, or does something irreversible, so your client knows what to ask you about. The tool catalog has a ready-made trust policy to paste in.

Try it without an account

The 3D Studio (free) server needs no sign-in: text to 3D, image to 3D and rigged avatars. Pick it above and connect in seconds.
