MasterCommander connects to your boat's electronics — Victron, SignalK, NMEA 2000, whatever you've got wired — and accumulates months of behavioral data. Baselines, patterns, what "normal" looks like for your boat. Plug in your own AI and get answers that actually mean something.
Same question, same boat, same AI — the only difference is context. MasterCommander exposes your boat via MCP, the open protocol that lets Claude, ChatGPT, or any AI ask your boat real questions.
