Text or a photo becomes a textured 3D model with a viewer link, a GLB, a rendered poster and embed code. Grok can look at what it made and fix it in words.

For Grok Bot, Grok and the xAI API
Give Grok a 3D studio, a body, and the Solana market.
Grok Bot routes every task to the best tool for it. One sentence connects all of three.ws: text and images become textured 3D models, rigged avatars, and a talking 3D body Grok can wear. Free, no account, no key. Sign the same URL in and Grok Bot also runs your agents, reads live pump.fun and Oracle market intel, and gets woken by your three.ws events. It never gets a tool that spends.

Add a custom MCP server called three-ws-grok at https://three.ws/api/mcp-grok
What Grok Bot can do with three.ws
Five jobs, one connector. Each card names the tools Grok Bot calls for it. Click an ask to copy it, then paste it into any Grok Bot task.
Rig
Any humanoid becomes an animation-ready avatar with a skeleton, from text, a photo or a GLB you already have. Save it as a body that speaks with lip-sync.

Find assets
Thousands of ready-made CC0 props, rigged characters and motion clips. Grok searches them before generating, so common asks come back instantly with paste-ready code.

Sign the same URL in with OAuth or a connector key and Grok Bot works with your three.ws agents: create and call them, give them memory and skills, report on them. It never gets a tool that spends.

Made on three.ws, just now
The latest models anyone generated on the free studio, the same pipeline Grok calls. Open one to spin it, download it, or put it on a page.
Run exactly what Grok runs
This box is an MCP client talking to /api/mcp-grok, the same server and the same calls Grok Bot makes. Every request and answer is logged as it happens. A cold GPU can take a few minutes; the job keeps running and the page collects it.
- The JSON-RPC transcript appears here: initialize, tools/call, then check_job until the model lands.
Your model lands here
Write a prompt and press Generate. You get an interactive model you can spin, plus the same viewer link and GLB Grok hands back.
Submitting the job
Asking the studio to start rendering.
That did not work
Three jobs to hand Grok
Each one names the tools Grok calls, in order. Click one to copy the instruction.
The skill file teaches Grok and Grok Bot the connector URL, runnable calls, the links every result returns, and the free limits. Upload it to Grok Skills, or tell Grok Bot to read https://three.ws/grok-skill.md.
Set it up anywhere Grok runs
One URL, https://three.ws/api/mcp-grok. Streamable HTTP. The free studio needs no sign-in; sign the same URL in to add your agents.
On paid Grok plans, custom connectors take a remote MCP URL. Only remote servers work there, which is exactly what this is.
- In Grok, open Connectors and add a custom connector.
- Paste
https://three.ws/api/mcp-grokand leave authentication off. - Ask Grok for a 3D model in any chat. It answers with a viewer link and a GLB.
Business and Enterprise workspaces may need an admin to allow custom connectors first.
The xAI Responses API connects remote MCP servers for you: pass the URL as a tool and Grok calls it server side. Set XAI_API_KEY and run.
curl
curl https://api.x.ai/v1/responses \

Grok Build, xAI's coding agent for the terminal, reads Claude Code's MCP servers, plugins, skills and marketplaces with no extra setup. So a project .mcp.json gives Grok Build the same tools, and the three.ws plugin adds the skills.
.mcp.json in your project
{
"mcpServers": {
"three-ws-grok": {
"type": "http",
"url": "https://three.ws/api/mcp-grok"
}
}
}
- Install Grok Build:
curl -fsSL https://x.ai/cli/install.sh | bash, thengrok --version. - Save the file above as
.mcp.jsonat the root of your project, and startgrokthere. - Type
/mcpsto see three-ws-grok connected, then ask for a model, a rig or a catalog search. - For the skills too, install the three.ws plugin for Grok Build: the same server plus six 3D skills and a
three-ws-tourcommand, with no hooks or scripts. Copy its folder into~/.grok/plugins/; the commands are below.
Install the plugin
git clone --depth 1 --filter=blob:none --sparse https://github.com/nirholas/three.ws three.ws-src git -C three.ws-src sparse-checkout set integrations/grok/three-ws mkdir -p ~/.grok/plugins && cp -r three.ws-src/integrations/grok/three-ws ~/.grok/plugins/three-ws
Compatibility per xAI's Skills, Plugins and Marketplaces docs. Source: xai-org/grok-build.
Let three.ws wake your Grok Bot
A Grok Bot routine can start from a webhook. Point a three.ws webhook at it and Grok Bot gets to work the moment something happens on your account: an agent run finishes, an automation fires, a message arrives, an approval is waiting, a model is forged. The event's JSON reaches the run as context.
- In Grok Bot, create a routine with a webhook trigger and an instruction, for example: "Read the three.ws event in the body. If it is approval.needed, summarize what the agent wants to do and message me." Grok gives you a URL and a key.
- On Developers, Webhooks, create a webhook with that URL, pick the events, and paste the key into Bearer token. It is stored encrypted and never shown again.
- Press Send test. Every delivery carries
Authorization: Bearer <key>plus the usual signature headers, retries with backoff, and shows up in the delivery log.
Grok Bot allows up to 200 runs an hour per routine, so pick the events you actually want a run for. Trigger format from xAI's Grok Bot docs. Full reference: docs/grok-bot.md.
Four recipes to schedule
Grok Bot runs tasks on a schedule with nobody watching. Each recipe is a guided MCP prompt the connector serves: it names the calls, never stops to ask, and ends with plain links. Copy the instruction into a Grok Bot task and set how often it runs.

Solana market brief

Six Grok Bot recipes, run against production walks through these three plus three more (an X post's image turned into a 3D model, a weekly agent report, a $THREE market brief) with the real output each one returned.
The Grok skill file
One Markdown file teaches Grok the whole toolbox: the connector, a curl fallback when no connector is attached, the free limits and the rule that it never spends. It is generated from the same code that serves the tools, so it never names one that does not exist.

What Grok gets
Read live from the server's tools/list, so this is always the real catalog.
The @-mention reply bot, live
Mention an agent on X and it can reply through the same tools Grok uses. Aggregate activity only, read live from the bot's own ledger.
Built for an agent that works while you sleep
Never hangs a task
A render can take minutes on a cold GPU. Every call answers within 40 seconds, with the model or a job id, and Grok collects it with check_job. Nothing times out half-done.
Your own quota
Every Grok user reaches us from xAI's cloud. Limits follow your MCP session, not xAI's IP address, so one busy user never spends yours.
A body, not just a file
create_agent_persona turns a rigged model into a named body that lip-syncs and emotes. Grok can bring the same body back in any later task.
Check the catalog first
Thousands of ready-made CC0 props, rigged characters and motion clips. Grok searches them before generating, so common asks come back instantly.
