Connect the ReUI MCP server to Grok CLI and build UI from the ReUI registry by chat.
Grok CLI connects to the ReUI registry in one step, so you can build UI from ReUI components, examples, and blocks right in your terminal.
Start Grok in your project, then open the MCP tab with /mcps and add a remote server:
Name: reui
URL: https://mcp.reui.io
Transport: HTTP (Streamable HTTP)The first time Grok CLI calls a ReUI tool, your browser opens a "Sign in with ReUI" prompt to authorize the connection. Approve it and you are set. If you do not have a ReUI account yet, a free one is created right there in the same flow, so there is nothing to set up in advance.
Run this one-liner in your project to add the ReUI skill:
curl -fsSL https://mcp.reui.io/install | node -This drops a ReUI skill file into your project so Grok CLI follows ReUI's build workflow: discovering the right components, pulling real source, and assembling them the ReUI way instead of guessing.
Almost every hiccup is a stale sign-in - the fix is to reconnect and authorize again.
/mcps and reconnect reui, then restart Grok./mcps and reconnect reui to sign in again./mcps and reconnect reui and retry your last prompt.For non-interactive runs where a browser prompt is not possible, create a
personal token at reui.io/account/mcp and pass
it as an Authorization: Bearer header on the server.
Describe the interface you want in plain language and Grok pulls the right ReUI components, examples, and blocks from the registry, then wires them into your project.
Use ReUI to scaffold an admin app - the app-shell with a collapsible sidebar and top bar, and a dashboard page with stat cards and a chart.Add a data-grid of orders with sorting, column filters, pagination, and row selection, wired to my /api/orders endpoint.Build a multi-step "create project" wizard with the ReUI stepper and form components, with validation on each step.Add a kanban board for support tickets with drag and drop, grouped by status, and a filters bar above it.Free items (the 17 components and every c-* example) install with no license. To let Grok install premium blocks, icons, and templates too, grab a Pro or Ultimate license - one license unlocks the whole premium registry and removes the daily MCP request limit. Then add your key to the project - two quick steps:
Copy your key from Account → Licenses into .env.local at the project root:
REUI_LICENSE_KEY=your-license-key-here{
"registries": {
"@reui": {
"url": "https://reui.io/r/{style}/{name}.json",
"headers": {
"Authorization": "Bearer ${REUI_LICENSE_KEY}"
}
}
}
}That is it - Grok can now install any premium item the MCP returns, and free items keep working through the same config. See License Setup for the full guide, or compare plans on the Pricing page.
Free includes components and examples, capped at 100 requests per day. A Pro or Ultimate license unlocks premium blocks, icons, and unlimited requests. See the full setup guide for other agents and options.
