Connect the ReUI MCP server to v0 and build UI from the ReUI registry by chat.
v0 connects to ReUI through its MCP Connections, so you can build production UI from the ReUI registry right inside a chat.
In v0, open the Connect tab (MCP Connections) and click Add MCP. Fill in the form:
Name: reui
Server URL: https://mcp.reui.io
Authentication: OAuthSave, and v0 starts the connection flow.
A browser window opens with a "Sign in with ReUI" prompt. Approve it to authorize the connection. If you do not have a ReUI account yet, a free one is created for you in that same 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 and pass it as an Authorization: Bearer header instead.
You do not install anything - the skill rides on the MCP from mcp.reui.io. Once the connection is authorized, v0 gets ReUI's tools and can call get_agent_skill to load the full ReUI workflow (the reuse-first rule and the discover, install, adapt order) as a document. If a build ever drifts off-pattern, tell it to "follow the ReUI skill" to reload that workflow.
Describe the interface you want in plain language and v0 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. Since v0 runs in the cloud, apply these steps inside the v0 project it is building, not on your local machine. To let v0 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 - v0 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, and authorize again, then restart v0.reui, and authorize again to sign in again.reui, and authorize 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.
