Connect the ReUI MCP server to v0 and build UI from the ReUI registry by chat.
v0 connects to ReUI in one step 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. Enter:
Name: reui
Server URL: https://mcp.reui.io
Authentication: OAuthAuthorize when v0 starts the connection.
The first time v0 uses the connection, 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.
There is nothing to install. The ReUI skill is delivered automatically through the MCP connection, so v0 follows ReUI's build workflow (discovering components, pulling examples, and assembling blocks) as soon as the connection is authorized.
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.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 includes components and examples with 100 requests per day. A Pro or Ultimate license unlocks premium blocks, icons, and unlimited requests. See pricing for the full breakdown, and the other agent guides for other agents.
