About
mnueron is a persistent memory layer for AI tools. Built local-first, open-source, and provider-agnostic so your context follows you across Claude, Cursor, Windsurf, Cline, and anything else you use — without a vendor owning it.
You explain your project conventions to Claude. You decide on an architectural pattern with Cursor. You catalog a finicky API in ChatGPT. Tomorrow, you start over — each tool is a goldfish.
The fix is obvious once you say it out loud: memory should be a layer, not a feature. It should live next to the user, follow them between tools, and never be hostage to one vendor's subscription.
That's mnueron. A small Node engine that runs locally, exposes six MCP tools (save, recall, list, get, delete, threads), and auto-wires itself into every AI tool already on your machine. Use whichever LLM you want. Switch any time. Your context comes with you.
Real boring tech making one interesting thing.
These aren't aspirations — they're design decisions baked into the architecture so we can't quietly walk them back later.
Your memories live in ~/.mnueron/memories.db on your machine. We can't read them. There's no telemetry, no upload, no 'opt out' to remember to flip. The hosted backend exists for people who want cross-machine sync — and is itself open source.
mnueron doesn't care if you use Claude, GPT-4, Gemini, Mistral, or Ollama. It's the memory layer underneath, not a wrapper around one vendor. The same memories surface in every tool you use.
Thirteen regex patterns plus Bearer/Basic-auth handling redact AWS, GitHub, OpenAI, Anthropic, Stripe, Slack, JWT, and PEM keys at write time. The original text is never persisted — not even to a temp file.
The client is MIT — fork it, ship it, sell on top of it. The hosted backend is FSL-1.1-Apache-2.0 — read it, contribute, self-host. Each version auto-converts to Apache 2.0 two years after release, so you can never be locked out of code you depend on.
mnueron installs in under a minute and runs entirely offline. No account, no card. Sync is optional and shows up only when you ask for it.
