# netscli
A network scanner written in Rust. CLI, terminal UI, and MCP server in
one binary.
```bash
cargo install netscli
```
Then:
```bash
netscli # interactive TUI
netscli discover # list live hosts on your default subnet
```
## Surfaces
- **CLI** — `netscli <cmd>` for scripts, cron, and piping into `jq`.
`--json` and `--yaml` output on every non-interactive subcommand.
- **TUI** — `netscli` alone opens a ratatui-based terminal UI with
autocomplete, command history, in-place progress, status footer,
and native scrollback/selection.
- **MCP** — `netscli serve` exposes nine tools over JSON-RPC on stdio
for Claude Code, Cursor, or any MCP client.
There's also a [desktop app](https://github.com/fstubner/netscli/releases)
that shares the same Rust core but isn't published to crates.io
(Tauri installers are attached to GitHub Releases instead).
## Commands
Host discovery, TCP port scan, subnet sweep, ping, traceroute, DNS
lookup (all record types), reverse DNS, ARP table with vendor
resolution, interface listing, and optional packet capture.
## Packet capture
Install the pcap-enabled variant via the release script:
```bash
NETSCLI_PCAP=1 curl -fsSL https://raw.githubusercontent.com/fstubner/netscli/main/scripts/install.sh | bash
```
This picks the right binary variant and also installs the platform's
packet-capture library (libpcap on Linux/macOS, Npcap on Windows). Or
build from source with `cargo build --release -p netscli --features pcap`.
