What this does

Quartermaster can connect directly to an AI assistant such as Claude or ChatGPT. Once connected, you can simply ask the assistant questions about your yacht or building in plain language, and it reads the answer out of Quartermaster itself — your real systems, your real service history, your real inventory.

Things people ask for:

• “What maintenance is overdue on the boat?”
• “When did I last change the engine oil, and how many hours ago was that?”
• “Read the service log for the generator and tell me what you would do next.”
• “Create tasks for everything due before we leave in June.”
• “Write me a maintenance summary for the last twelve months I can send to a surveyor.”
• “Do I have a spare impeller on board, and which locker is it in?”

The assistant is not guessing or working from a copy of your data. It reads Quartermaster live, each time you ask, and anything it creates shows up in your app straight away — recorded under your name, just as if you had typed it in yourself.

You decide exactly what it can see

This is the part worth reading carefully. An AI assistant never gets your Quartermaster password, and it never gets access to your whole account.

When you connect one, Quartermaster shows you a permission screen where you choose:

1. One yacht or building. Not all of them — one. If you manage a fleet, the assistant only ever sees the single vessel you picked. There is no way for it to reach another, even if you ask it to.
2. Which parts it may read, and whether it may make changes. You tick these individually: tasks, systems, the service log, service schedules, inventory and files. Each one is either read-only or read-and-change.

Permission to make changes starts switched off. If all you want is a report or a second opinion, leave every “manage” box unticked and the assistant can read but never touch anything.

A few things are simply not on offer, no matter what an assistant asks for: it can never see or change your crew list, it can never upload or delete files, and it can never reach your subscription or billing details.

Connecting Claude

In Claude, go to Settings → Connectors and choose to add a custom connector. When it asks for the server URL, enter:

https://quartermaster.me/mcp

Claude will send you to Quartermaster to sign in and choose what to share. Pick your yacht or building, tick the permissions you want, and press Allow access. That is the whole setup — you will be returned to Claude, and it can start answering questions about your vessel immediately.

Connecting ChatGPT

ChatGPT works the same way. In Settings → Connectors, add a custom connector and give it the same address, https://quartermaster.me/mcp. You will see the same Quartermaster permission screen, choose the same way, and you are done.

Connectors are not available on every ChatGPT plan. If you cannot find the setting, that is a limitation on ChatGPT's side rather than anything to do with your Quartermaster account.

Check the name before you allow access

The permission screen shows you the name of the application asking for access, and right underneath it a note saying that the name has not been verified by Quartermaster. That note is there for a good reason: any application can call itself anything it likes when it asks.

So before you press Allow, check two things:

• You started this yourself, a moment ago, from the AI assistant you meant to use.
• The website address shown on the screen is the one you expect it to be.

If a permission screen appears that you did not ask for — say you followed a link in an email — press Deny. Nothing is shared unless you approve it.

Seeing and removing connections

Everything you have connected is listed in the Quartermaster app under Account → AI connections. For each one you can see which yacht or building it was given, exactly what it is allowed to do, when you connected it and when it last looked at your data.

Pressing Revoke cuts it off immediately — not at the end of the day, not when something expires. The next thing that assistant tries to do will fail. If you ever feel unsure about a connection, revoke it; reconnecting later takes under a minute.

Connections are personal to you. If you are crew on someone else's yacht, connecting an assistant gives it no more access than you have yourself — and if your role on that vessel is read-only, you will not be able to grant permission to change anything. Likewise, if the owner later removes you from the crew list, any assistant you connected loses access at the same moment you do.

Good practice

• Start read-only. Connect with reading permission only, see whether you like the answers you get, and add change permissions later if you want them.
• Read what it proposes before you let it act. Ask the assistant to list the tasks it thinks you need before telling it to create them. It is very good at reading a service history and spotting what has slipped; it is still worth your eye on the list.
• Ask it to explain itself. “Why do you think that is overdue?” will get you the schedule and the last service date it based the answer on.
• Keep deletions to yourself. There is rarely a good reason to ask an assistant to delete service history. Removing a system also orphans its logs, schedules and inventory.

As a safety net, Quartermaster limits how many changes a single connection can make in an hour, and keeps a record of every change an assistant makes on your behalf. A misbehaving assistant runs into a wall long before it can work through your whole task list.

A note on notes

An AI assistant reads the text in your Quartermaster records, including the notes on tasks and systems. If you share a vessel with other people, bear in mind that anything written in those notes is text the assistant will read and may act on. It is worth keeping notes factual, the same way you would if they were going to be read out at a handover.
