You need Node.js 20+ and npm 10+ on your machine.
node --version # want v20.x or higher
npm --version # want 10.x or higher
Don't have Node? Install from nodejs.org/en/download (pick the LTS installer for your OS).
Install
npm install -g mnueron
mnueron setup
mnueron setup is an interactive wizard. It scans for installed AI tools (Claude Desktop, Claude Code, Cursor, Windsurf, Cline) and offers to wire mnueron into each.
Verify it works
- Restart whichever AI tool you wired up (close it fully, reopen).
- Open a new chat.
- Ask: "Save a memory: I prefer 2-space indentation in JavaScript."
- Start a brand-new chat, ask: "What indentation do I prefer in JavaScript?" — the AI should call
memory_recalland answer correctly. - Run
mnueron dashboardin a terminal and openhttp://localhost:3122— you should see the memory there.
