Personal Understanding MCP server

Lets your AI keep a private, word-for-word memory of your chats and recall it with proof.

Personal Understanding is a memory helper that lives on your own computer. It saves what you say word for word, then lets your AI look things up later and show you exactly where each memory came from. It is handy if you use ChatGPT or Claude a lot and want it to actually remember you across sessions.

What is an MCP server? The 30-second version

On its own, your AI can only chat with what is in front of it. An MCP server is a small helper program that gives your AI a new skill or a connection to something. This one connects your AI to a memory folder on your machine, so it can save your messages and search them later when you ask. You do not install anything from a big company; it runs locally.

What this MCP server does

When you send a personal message, this helper first saves your exact words in a file, with a fingerprint and a timestamp, before anything else happens. Then it builds small notes on top, like events, people, and topics, and links each note back to the quote it came from. Later, when you ask your AI something like what you said about a game or a book, the helper searches those notes and the original quotes. It can even find memories that share no words with your question, by following topic links, and it shows you the path it took. You get an answer plus the source quote, so you can check it.

Flow diagram: you ask your AI “What did I say about that game with weak hits?”, on your own computer the Personal Understanding MCP server works with your computer, and you get back answer with the original quote.

Try asking your AI

“What did I say about that game where the hits felt weak?”
“Remind me what I told you about my cousin's wedding.”
“I forget, we talked about a book I might like. Can you find it?”
“Where did you get that thing about my reading taste?”

What it gives back to you

You get answers in the chat, plus the original quotes they came from. It can also give you lists of related memories, a short summary of what it found, and a note about anything it held back or was unsure about. If it does not know, it says so instead of guessing.

Before you start

What you need

Python 3.10 or newer on your computer
The Claude desktop app or another AI client that supports MCP servers
A folder where the memory files can live (the setup creates it for you)

Good to know

It reads and writes files in a memory folder on your computer, so keep that folder private and back it up if the memories matter to you.
