open-memex MCP server

open-memex is a memory helper for AI coding assistants. It saves the things you tell your assistant, like decisions and lessons, as simple text files on your own computer. Next time you open a chat, your assistant already knows them, in VS Code, Cursor, Claude Code, and other editors.

What this MCP server does

You tell your AI something worth keeping, like "remember: we deploy on Fridays". The AI uses this helper to write that fact into a small Markdown file on your computer. When you start a new chat, the helper hands your AI the most relevant saved facts automatically, so it starts out already knowing them. You can also ask your AI to search the memory when you need something specific. Everything stays on your machine, in files you can open and edit yourself.

What you can do with it

• Save a fact or decision so your AI remembers it later
• Ask your AI what it already knows about your project
• Search your saved memories by keyword, even with different wording
• Replace an old fact with a newer one while keeping the history
• Mark a memory as outdated when it no longer applies
• Share chosen memories with your team through a normal code review
• Check your memory for duplicates or stale entries

Try asking your AI

• “Remember that this project deploys on Fridays”
• “When does this project deploy?”
• “Search my memories for anything about login”
• “Save that I prefer short code changes”
• “What do you already know about our database setup?”

What it gives back to you

You get answers in the chat, drawn from your saved memories. When your AI saves something, it confirms what it stored. When you search, you get a short list of matching memories with their text. Some commands also give you a report, like a list of duplicates or outdated entries.

Who it's for

Developers and anyone who uses an AI coding assistant daily and is tired of re-explaining their project every session.
