Verdict

Pick Cua Driver if you prefer the more popular, battle-tested option, and you want a local (stdio) server that keeps data on your machine.

Pick Quackback MCP Server if you want the official, vendor-maintained server, and you want a hosted/remote server with nothing to install.

Add Cua Driver

Install / run
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/trycua/cua/main/libs/cua-driver/scripts/install.sh)"

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

{
  "mcpServers": {
    "cua-driver": {
      "command": "cua-driver",
      "args": [
        "mcp"
      ]
    }
  }
}

Add Quackback MCP Server

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

{
  "mcpServers": {
    "quackback-mcp-server": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://{host}/api/mcp",
        "--header",
        "Authorization: Bearer ${QUACKBACK_API_KEY}"
      ]
    }
  }
}

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