CLI: registry setup, license, non-interactive install

Registry setup (one-time, per project)

Free items (the ReUI components and all c-* examples) need only the plain string registry in components.json:

{ "registries": { "@reui": "https://reui.io/r/{style}/{name}.json" } }

Premium items (blocks and Motion Icons) require a ReUI license at install:

1. Add the key to .env.local:

REUI_LICENSE_KEY=your-license-key

2. Switch components.json to the authenticated object form:

{
  "registries": {
    "@reui": {
      "url": "https://reui.io/r/{style}/{name}.json",
      "headers": { "Authorization": "Bearer ${REUI_LICENSE_KEY}" }
    }
  }
}

The shadcn CLI expands ${REUI_LICENSE_KEY} from .env.local inside components.json. MCP client configs expand environment variables too, but each client has its OWN syntax, so wire the ReUI MCP server with the form that client understands:

• Claude Code (.mcp.json, ~/.claude.json): "Authorization": "Bearer ${REUI_LICENSE_KEY}"
• Cursor (.cursor/mcp.json) and VS Code: "Authorization": "Bearer ${env:REUI_LICENSE_KEY}"
• OpenCode (opencode.json): "Authorization": "Bearer {env:REUI_LICENSE_KEY}"
• Codex (~/.codex/config.toml): bearer_token_env_var = "REUI_LICENSE_KEY" - Codex reads the variable itself, so there is no header to write

Only a client with no interpolation at all needs the raw reui_pat_... token, and then only in a file that is never committed. Copying the components.json form into a client that does not expand it is the common failure: the literal ${REUI_LICENSE_KEY} placeholder is sent to the server as the credential and every call comes back 401.

The MCP get_project_context tool returns the right config. Full guide: https://reui.io/docs/registry?ref=skill

Installing

Use the project's package runner (check packageManager):

npx shadcn@latest add @reui/<name> --yes      # npm
pnpm dlx shadcn@latest add @reui/<name> --yes  # pnpm
bunx --bun shadcn@latest add @reui/<name> --yes # bun

--yes skips confirmation prompts. The CLI auto-detects the package manager from the lockfile (there is no --package-manager flag). It also resolves the correct base+style variant from components.json, so do not pass a style.

<name> is the item name exactly as a ReUI tool returned it. The @reui/ prefix is for ReUI items only:

• The shadcn/ui components ReUI builds on (button, dialog, select, card, ...) are not ReUI items. Install them from shadcn by bare name: npx shadcn@latest add button --yes.
• badge and alert exist in both registries: @reui/badge and @reui/alert are ReUI's components, bare badge and alert are shadcn's.
• In an item's registryDependencies, a @reui/<name> entry is a ReUI item and a bare name is a shadcn/ui item. add installs both, so you never add them by hand.
• Templates are not registry items. Download a template from its page on reui.io (https://reui.io/templates?ref=skill); no shadcn add command installs one.

Handling prompts and conflicts

• Always pass --yes so the CLI does not block on confirmation prompts.
• Do NOT pass --overwrite by default. If the CLI reports an existing file, read the output and resolve deliberately: install under a different name, adjust the path, or ask the user. Only use --overwrite when the user explicitly wants to replace a file.
• Preview first when touching an existing project: npx shadcn@latest add @reui/<name> --dry-run shows what would change; --diff <file> shows a specific file's diff. Use these before overwriting.
• Run from the project root so components.json and .env.local are found.

Free vs premium boundary

• Public, no key: c-* examples and the ReUI components (@reui/data-grid, @reui/badge, ...) that those examples depend on.
• Key required at install: blocks (@reui/<category>-N) need a Pro or Ultimate license; Motion Icons (@reui/icons/...) need Ultimate.
• Templates are downloads from their page on reui.io, not installs: free ones need only a ReUI account, and each template's page says what the others need.

If an install 401/403s, the license key is missing, invalid, or the plan does not cover that resource (blocks: Pro or higher; icons: Ultimate). Point the user to https://reui.io/account?ref=skill (their key) or https://reui.io/pricing?ref=skill (upgrade).

If an install 404s, the name is not a ReUI item. Read the CLI's error message, which names the right install command when there is one, or look the name up with get_install_command or search.
