Cursor

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.

Connect ReUI

Add the ReUI MCP server

Add the reui server to Cursor in one click. Cursor opens, shows the server, and asks you to confirm - approve it, then reload.

Add to Cursor

Prefer to set it up by hand? Add ReUI to .cursor/mcp.json in your project, then reload Cursor:

.cursor/mcp.json

    }
  }
}

Sign in with ReUI

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:

.cursor/mcp.json

{
  "mcpServers": {
    "reui": {
      "url": "https://mcp.reui.io",
      "headers": {
        "Authorization": "Bearer reui_pat_your_token_here"
      }
    }
  }
}

Install the ReUI skill

Run the one-line installer in your project so Cursor follows ReUI's build workflow:

Terminal

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.

Build with ReUI

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.

Prompt

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.

Prompt

Add a data-grid of orders with sorting, column filters, pagination, and row selection, wired to my /api/orders endpoint.

Prompt

Build a multi-step "create project" wizard with the ReUI stepper and form components, with validation on each step.

Prompt

Add a kanban board for support tickets with drag and drop, grouped by status, and a filters bar above it.

Troubleshooting

Almost every hiccup is a stale sign-in - the fix is to reconnect and authorize again.

Tools missing, greyed out, or "not connected" - the server did not finish connecting. To fix it, re-open Cursor's MCP settings and sign in to reui again, then restart Cursor.
401 or "authentication required" - your ReUI session expired. To fix it, re-open Cursor's MCP settings and sign in to reui again to sign in again.
Requests hang or the session drops mid-build - long sessions can lose the connection. To fix it, re-open Cursor's MCP settings and sign in to reui again and retry your last prompt.
429 "daily limit reached" - you hit the free limit of 100 requests per day. Sign in with your ReUI license for unlimited access, or wait for the next day.

Plan scope

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).
