The TanStack CLI includes a Model Context Protocol (MCP) server that enables AI assistants to:

• Create TanStack Start projects with add-ons
• Search and fetch TanStack documentation
• Explore the TanStack ecosystem (partners, libraries)

Claude Desktop Setup

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

  "mcpServers": {
    "tanstack": {
      "command": "npx",
      "args": ["@tanstack/cli", "mcp"]
    }
  }
}

Restart Claude Desktop. Then try:

"Create a TanStack Start project called 'my-app' with Clerk auth and Drizzle ORM"

Or:

"How do I use loaders in TanStack Router?"
