Compound Memory MCP server

Compound Memory is a memory store that lives on your own computer as ordinary text files. It lets several AI assistants share the same notes, so things you told one of them are not forgotten by the next. It is handy if you use AI every day and are tired of repeating yourself.

What this MCP server does

You tell your AI something worth keeping, like a preference or a rule for a project. The AI uses this helper to write it into a plain text file in a folder on your computer. Later, when you ask a question, the AI searches that folder and pulls back the notes that match. Each time a note proves useful, the AI marks it as more reliable, and notes that go unused slowly fade into an archive. If you use more than one AI assistant, they can all read and add to the same folder.

What you can do with it

• Save facts and preferences so your AI remembers them next time
• Search your saved notes by keyword when you ask a question
• Mark a note as helpful or wrong so the store gets more accurate
• Link related notes so they show up together
• Keep separate private notes for each AI assistant alongside shared ones
• Merge many small notes into fewer, clearer ones
• Keep an automatic version history of every change

Try asking your AI

• “Remember that I prefer short answers with tables.”
• “What do you already know about how we deploy this project?”
• “That note about the timeout was helpful, mark it as confirmed.”
• “Search your memory for anything about our weekly report format.”

What it gives back to you

You get back a short list of matching notes, each with its text and a confidence score, shown right in the chat. When the AI saves something, it confirms the note was written. When you give feedback, it shows the updated confidence and how many times the note has been used.
