# DeviceShelf

> DeviceShelf is a local-first network scanner for macOS, Windows, Linux, iOS
> and Android. It discovers every device on your LAN, identifies what each one
> is, shows open ports and a security report, and offers live monitoring and
> AI-assisted device identification (bring your own AI key). Scan results stay
> on the device that ran the scan — no account, no cloud, no telemetry.

## What it does

- One-click network scan and device discovery across every interface/subnet at once.
- Deep device identification, incl. passive DHCP fingerprinting (Fingerbank) and AI device ID.
- Built-in security report: open ports & services, deep probes (TLS, SSH, SMB, HTTP).
- Presence monitoring & alerts (new device, device down, open port, WAN/DNS/TLS/domain changes, CPU/RAM/disk).
- Per-device live bandwidth, physical topology map (LLDP/CDP + bridge FDB), built-in syslog server.
- MCP server (Server edition): exposes the live inventory and monitoring state to a local AI assistant (e.g. Claude Desktop) over the Model Context Protocol — ask "what's online", "which certificates expire soon", "what's vulnerable". Strictly local, read-only by default, included with the licence.
- Diagnostics toolbox: ping, traceroute, DNS, speed test, Wake-on-LAN.
- Snapshots, favourites, tags, and exportable/shareable reports.
