OpenMyMemo MCP server

OpenMyMemo

Your AI memory as a plain folder on your own computer. See exactly what models remember about you; let Claude, Codex, Cursor or any MCP app share it, so what you tell one the others know too, and see every change they make, with one click to undo. If an account gets banned, a vendor shuts down or you switch models, your memory comes with you.

Why I built this

My OpenAI account was banned on October 2, 2026, with no warning and no specific explanation. I had used ChatGPT since it launched in late 2022, and its year-end recap put me in the top 1% of users. I appealed and never got a reply. Nearly four years of conversations, and everything ChatGPT had learned about me, went with the account.

I had thought of that memory as mine. It wasn't. It lived on OpenAI's servers, in an account they could close at any time, and when they did, the memory went with it, with no one to ask for it back.

OpenMyMemo is what I wish I'd had: my AI memory as a folder on my own computer. Any model can read it, I can see and undo every change a model makes, and no single company can take it away.

Get started

There are two ways in. Both use the same memory folder, the same panel and the same core, so you can switch or use both.

The Mac app

For everyone: no terminal, no config files, no Python to install.

1. Download OpenMyMemo--arm64.dmg from the latest release (a Mac with Apple silicon, macOS 12 or later).
2. Open it and drag OpenMyMemo to Applications. (Opened straight from the disk image, it offers to move itself there.)
3. Open OpenMyMemo from Applications. Release builds are signed and notarized and open like any app. A build without a Developer ID signature (one you built, or a fork's) needs one extra step the first time: on macOS 15 and later, try to open it, then go to System Settings → Privacy & Security and click Open Anyway; on earlier versions, right-click the app and choose Open.
4. The first start downloads Python and the libraries OpenMyMemo runs on, about 25 MB and usually under a minute, into ~/Library/Application Support/ai.mymemo.openmymemo/. It happens once; after that the app starts in a couple of seconds, also offline.
5. A short guide connects the AI apps on your Mac with one click each and brings over the memory ChatGPT, Claude or Gemini already have. Your memories live in ~/OpenMyMemo.

The app shows the panel in its own window, puts the number of changes to review in the menu bar, and notifies you when an AI app changes something. To update, download the new disk image and drag it to Applications again; your memory folder isn't touched.

The app also installs an openmymemo command, which the AI apps it connects run (Settings → Advanced shows where). It is the full command line below, so you can use it in Terminal too.

The command line

For developers, and anyone who prefers a terminal. Nothing is fenced in: everything the app does is a command, and the folder format (docs/MEMORY_FORMAT.md) is the interface. Requires uv:
