Connect the ReUI MCP server to Cursor and build UI from the ReUI registry by chat.
Cursor connects to ReUI in two quick steps: point it at the hosted MCP server, then sign in and start building UI by chat.
Add the reui server to Cursor in one click. Cursor opens, shows the server, and asks you to confirm - approve it, then reload.
Prefer to set it up by hand? Add ReUI to .cursor/mcp.json in your project, then reload Cursor:
{
"mcpServers": {
"reui": {
"url": "https://mcp.reui.io"
}
}
}The first time Cursor calls a ReUI tool, a browser window opens to authorize the connection. Click "Sign in with ReUI" to complete the OAuth prompt. If you do not have an account yet, a free ReUI account is created for you right in that flow, so there is nothing to set up in advance.
For headless or CI use where no browser is available, create a personal token at reui.io/account/mcp and add it as an Authorization header on the same server entry:
{
"mcpServers": {
"reui": {
"url": "https://mcp.reui.io",
"headers": {
"Authorization": "Bearer reui_pat_your_token_here"
}
}
}
}Run the one-line installer in your project so Cursor follows ReUI's build workflow:
curl -fsSL https://mcp.reui.io/install | node -This drops a ReUI skill file into your project. Cursor reads it to learn how ReUI wants components discovered, assembled, and wired, so its output stays on the ReUI registry instead of freehand markup.
Describe the interface you want in plain language and Cursor 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 Cursor 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 - Cursor 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.
Almost every hiccup is a stale sign-in - the fix is to reconnect and authorize again.
reui again, then restart Cursor.reui again to sign in again.reui again and retry your last prompt.Free covers components and examples at 100 requests/day; a Pro or Ultimate
license unlocks premium blocks, icons, and unlimited requests (add
the @reui registry via License Setup to install
them).
