Starwind UI MCP Server

Official MCP Registry · io.github.starwind-ui/mcp

A TypeScript Model Context Protocol server for Starwind UI v3 and Starwind Pro. It gives AI clients current, framework-aware guidance for Astro and React projects.

Quick start

For the maintained client setup guide, see the Starwind UI MCP documentation.

Codex (~/.codex/config.toml):

[mcp_servers.starwind_ui]
command = "npx"
args = ["-y", "@starwind-ui/mcp"]
enabled = true

Claude Code (.mcp.json) or Cursor (.cursor/mcp.json):

{
  "mcpServers": {
    "starwind-ui": {
      "command": "npx",
      "args": ["-y", "@starwind-ui/mcp"]
    }
  }
}

Restart the client or reload its MCP servers after changing the configuration.

v3 model

Starwind UI v3 has three related surfaces. The MCP keeps them distinct:

The server validates these layers against the versioned ai-manifest.json, caches validated data, and falls back to a bundled v3 snapshot if the site is unavailable.

Tools

Tool calls return both readable JSON text and MCP structuredContent.

Requirements and behavior

• Generated v3 CLI commands require Node.js 22.12.0 or newer.
• starwind_init targets existing Astro 5+ or React 18+ projects and lets the CLI auto-detect the framework unless framework is supplied.
• Free @starwind-pro/* catalog blocks work after ordinary initialization. Paid blocks require explicit authorization; pass pro: true only when it is required.
• Starwind Pro blocks currently target Astro. React searches omit them, and React add requests reject them explicitly.
• Migration is interactive by default. Set yes: true only when backup-and-overwrite behavior is intended.
• Package-manager and project context are detected locally when possible, and add commands pass the resolved package manager to the CLI. No tool executes the generated command.

Upgrading from free to Pro

The MCP keeps Pro discoverable without forcing paid setup. Search results link to the Pro catalog, free Pro blocks remain directly installable, and paid results include a structured proUpgrade path with purchase and installation links.

For an existing Astro project, the MCP recommends:

pnpm dlx starwind@latest setup --yes

The setup command auto-detects the project's package manager, so it does not need a --package-manager flag. It prepares the Pro registry and .env.local; replace the STARWIND_LICENSE_KEY placeholder with the purchased key, then run the returned deferredCommand. Treat the key as sensitive: keep .env.local out of source control and never expose the key in logs or client-side code. A project initialized with pro: true receives the equivalent init --pro command instead.

Development

pnpm build
pnpm lint
pnpm test:run

Run the opt-in production manifest contract test with:

RUN_LIVE_CONTRACT_TESTS=1 pnpm test:run src/utils/starwind_live_contract.test.ts
