The example below, asking ChatGPT to sort my Big Four for an autumn Highlands route, is just one prompt. It could have been almost anything. The point is that once an assistant can see your own gear, kits, packs and trips, that's the tip of what it can help with.
Set up once
MCP is a standard that lets an assistant use tools from another service. Find it under Edit profile › Developer access, copy the endpoint into ChatGPT, Claude, or Codex, and sign in with OutPack when it asks. It only ever reaches your own account, no long-lived secret to paste in and lose track of.
Then ask it something real
Once it's connected, OutPack shows up as a tool the assistant can reach for, the same way it reaches for web search.
OutPack sits next to web search and deep research, one more tool ChatGPT can reach for.
No copying a gear list into the chat. It already knows what's in the inventory.
It read my actual inventory, weighed up the packs, shelters, bags and mats I already own, and came back with a Big Four built for that specific route: a shelter picked for exposed ground, a bag rated for cold damp nights, and a lighter mat swapped for a warmer one further down the page. Every gram in that table came from gear I've actually weighed, not a guess.
Pulled straight from my inventory, not typed out from memory.
Not just the Big Four
That one question only shows a slice of it. The same connection reaches kits, packs and trips too, so it's just as able to put together a kit for a new activity, add a trip and pack it from your inventory, or tell you what's still unpacked the night before. And it's whichever assistant you already have open doing the asking, not another app to learn.
It can edit and delete as well as read, so it's worth being deliberate with what you ask for. Deletes are flagged so the assistant should check with you first, but read what it's about to do before you wave it through, the same as you would for anything else that can touch your data.
That's the bit I like: the assistant is working with my gear, in my environment, with the tools I already reach for, so the planning gets richer instead of starting from a blank page. I hope it does the same for your next trip.
