A network scanner you
can talk to

Discover hosts, scan ports, resolve DNS, capture packets. Use it from a terminal, a desktop app, or let your AI agent call the MCP server — or the CLI directly.

Four interfaces, one library

Every surface calls the same netscli-core. Full docs →

Desktop app

A standalone desktop application for when you'd rather not open a terminal. Scan ports, discover hosts, look up DNS records, inspect your ARP table. Available for Windows, Linux, and macOS.

Terminal UI

An interactive terminal interface. Type / to see available commands, use tab to autocomplete, arrow keys to browse history. The status bar shows your IP and live traffic rates.

Command line

Every scan ships as a standalone subcommand with --json and --yaml output. Pipe results into jq, call it from a shell script, or have an agent invoke it directly without the full MCP server.

$ netscli scan 1.1.1.1 -p 80,443 --json
[
  { "port": 80,  "open": true, "service": "http"  },
  { "port": 443, "open": true, "service": "https" }
]

$ netscli discover --json | jq '.[].ip'
"192.168.1.10"
"192.168.1.21"
"192.168.1.57"

MCP server

Run netscli serve and point Claude Desktop or Cursor at it. Your agent gets 9 tools — host discovery, port scanning, DNS, ARP, and more — over standard JSON-RPC.

// claude_desktop_config.json
{
  "mcpServers": {
    "netscli": {
      "command": "netscli",
      "args": ["serve"]
    }
  }
}
