Configure Cursor

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "netextender": {
      "command": "node",
      "args": ["C:/codeBase/netextender-mcp/dist/index.js"],
      "env": {
        "NETEXTENDER_CLI": "C:/Program Files/SonicWall/SSL-VPN/NetExtender/nxcli.exe",
        "NETEXTENDER_PROFILE": "<your-profile>",
        "NETEXTENDER_SERVER": "host:port",
        "NETEXTENDER_DOMAIN": "<your-domain>",
        "NETEXTENDER_USERNAME": "<your-vpn-username>",
        "NETEXTENDER_PASSWORD": "<your-vpn-password>",
        "NETEXTENDER_ALWAYS_TRUST": "true"
      }
    }
  }
}

After publishing to npm:

"netextender": {
