netscli

netscli is an open-source network scanner written in Rust. It discovers hosts on a subnet, scans TCP and UDP ports, resolves DNS (including mDNS/Bonjour), reads the ARP table with vendor lookup, and optionally captures packets via Npcap. The same functionality is available from a command line, a terminal UI with autocomplete, a desktop app, or a Model Context Protocol (MCP) server that AI agents like Claude Code and Cursor can call directly.
