Verdict

Pick KoliBri MCP Server if you want a hosted/remote server with nothing to install, and you want zero-setup with no API key.

Pick 21st.dev Magic MCP if you prefer the more popular, battle-tested option, and you want a local (stdio) server that keeps data on your machine.

Add KoliBri MCP Server

Install / run

npm install -g @public-ui/mcp

Paste into ~/Library/Application Support/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "kolibri-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://public-ui-kolibri-mcp.vercel.app/mcp"
      ]
    }
  }
}

Claude Desktop connects to remote servers through the `mcp-remote` proxy (installed on first run via npx). Restart Claude Desktop after saving.
