Tools you can run yourself, on your boat or your laptop. Each one is open source under MIT, signed at release, and small enough to fit on a thumb drive. Pick what's useful.
A command-line scanner you run from your laptop. Surveys every device on your boat's network, identifies what's there, and flags anything that looks like a known marine advisory. macOS, Linux, Windows.

A CLI that plays a sailing scenario out as real NMEA-0183 / NMEA-2000, and decodes a NMEA stream back to readings. Point OpenCPN at it, or pipe sim → decode. Runs from the repo today; npx + standalone binaries coming.

The .pkg / .deb installer that turns a Mac mini, NUC, or Raspberry Pi into your boat's hub. Bundles Docker runtime and the core 32°N stack. One installer, one runtime, same everywhere.

Developer tools
If you're writing code that talks to the platform — apps, NMEA-2000 integrations, custom data sources — these are the utilities I use myself.
Reading raw frames off a live CAN bus (a USB gateway, can0)
is the one piece the NMEA toolkit doesn't do yet — it needs OS-level
socket access. It's on the list; for now nmea decode reads
a NMEA stream over TCP, a file, or stdin.
The Marine Security Scanner runs as a Model Context Protocol server (`mss serve`), so an AI assistant can query it directly: "scan the boat for new devices," "show me the open advisories." Bundled with the CLI download.
