Connect the ReUI MCP server to Replit and build UI from the ReUI registry by chat.
Replit connects to ReUI in one step: add the ReUI MCP server to your Replit Agent, and you can build UI from the ReUI registry by chat.
In your Repl, open the MCP Servers settings in the Integrations pane, then click + Add MCP server. Enter a display name and the server URL:
Display name: reui
Server URL: https://mcp.reui.ioThen click Test & save. For CI or a headless setup, open Advanced settings first and add a custom header - Authorization: Bearer YOUR_REUI_LICENSE_KEY - with your license key from .
Test & save opens a "Sign in with ReUI" window so you can authorize the connection. If you do not have a ReUI account yet, a free one is created for you as part of this flow. After you approve, Replit finishes the connection and the ReUI tools are ready.
The skill comes from mcp.reui.io itself, no separate registry - two ways:
get_agent_skill to load the full workflow (discover, read the API, install, then adapt by reuse) as a document. If a build drifts off-pattern, tell it to "follow the ReUI skill" to reload it.curl -fsSL https://mcp.reui.io/install | node -Replit runs a full Linux workspace, so the Agent installs ReUI items with the shadcn CLI directly, exactly as the MCP returns them:
Free items (the 17 components and every c-* example) install with no license. To install premium blocks or Motion Icons, add the @reui registry to components.json and store your key as a Replit Secret named REUI_LICENSE_KEY; Replit exposes Secrets as environment variables, so the CLI reads it automatically. See License Setup.
Describe the interface you want in plain language and Replit 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 Replit.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.
