Geniuz is an open-source MCP server that gives Claude, Hermes, and other AI agents a memory that lasts. Normally every conversation starts from zero โ€” you re-teach your context, preferences, and decisions each time. Geniuz keeps them: the standards you set, the calls you made, and the reasons behind them, recalled by meaning across sessions and compactions. It runs entirely on your own machine โ€” semantic search via a bundled ONNX model, no cloud, no account, no API keys โ€” and plugs into Claude Desktop through Anthropic's MCP standard on macOS, Windows, and Linux. Free and MIT-licensed. Built by mVara, who run their own fleet of AI agents on it every day.


Features

  • Continuous Memory : Persistent memory for AI agents that survives every session
  • Semantic Recall : Find memories by meaning, not keywords โ€” ask in plain language and get what's relevant
  • Survives Compaction : Memory persists across session boundaries and context resets, so nothing is lost when the window clears
  • Local-First : Runs entirely on your machine โ€” on-device semantic search, no cloud, nothing leaves your computer
  • No Keys, No Account : Works with zero API keys, no signup, no telemetry
  • One-Command Setup : geniuz mcp install wires it into Claude Desktop instantly โ€” zero config
  • MCP Native : Connects to Claude, Cursor, Windsurf, Aider, or any MCP client through Anthropic's standard
  • Three Simple Tools : remember, recall, recent โ€” small enough to fit in any agent's working memory
  • Shared Team Memory : Multiple agents and teammates can share one memory and hand off context (Team tier)
  • Open Source : MIT licensed and fully functional for free
  • Cross-Platform : Native apps for macOS, Windows, and Linux

Nullstack features and specs

  • Full-Stack Capabilities
    Nullstack allows for the development of both client-side and server-side functionalities within a single project, providing a more unified development process.
  • Seamless SSR
    It offers built-in support for server-side rendering, improving performance and SEO without the need for complex configurations.
  • Zero tooling
    Nullstack provides a setup that requires minimal configuration and does not depend heavily on additional tools, simplifying the development workflow.
  • Component-based Architecture
    Promotes the use of components, encouraging modularity and reusability of code, which can improve maintainability and scalability of applications.
  • Hot Module Replacement
    Supports HMR, allowing developers to see immediate changes in their applications without refreshing the entire page, improving development efficiency.

Possible disadvantages of Nullstack

  • Smaller Community
    Compared to more established frameworks, Nullstack has a smaller community, which can result in fewer resources and third-party tools.
  • Learning Curve
    Developers need to learn the Nullstack-specific ways of handling both front-end and back-end development, which might be a hurdle for those accustomed to other frameworks.
  • Limited Ecosystem
    Due to its newer and less widely adopted nature, there might be limited third-party libraries and plugins readily available compared to more mature frameworks.
  • Rapidly Evolving
    Being relatively new and possibly evolving quickly, developers might face breaking changes more frequently compared to more established technologies.

Questions & Answers

As answered by people managing Nullstack and Geniuz.

Who are some of the biggest customers of your product?

Geniuz's answer:

  • mVara โ€” runs its own fleet of AI agents on Geniuz daily, in production
  • First Chair Destinations โ€” knowledge management for vacation rentals
  • Tom Ferry International โ€” market intelligence for real estate professionals

Which are the primary technologies used for building your product?

Geniuz's answer:

Built in Rust. On-device semantic search runs on ONNX Runtime with a bundled embedding model and tokenizer, so inference happens locally with no network calls. Memory is stored in an embedded SQLite database. It connects to AI clients through Anthropic's Model Context Protocol (MCP), and ships with a terminal UI (ratatui) plus native desktop apps for macOS, Windows, and Linux.

What's the story behind your product?

Geniuz's answer:

Geniuz came out of mVara's own work running a fleet of AI agents. The recurring problem was that every agent forgot everything between sessions โ€” every morning was Day 1, re-teaching context, standards, and decisions. mVara built Geniuz to solve that for themselves: a local memory layer their agents share and hand off context through, every day. The product is what the company actually uses, which is why it's shaped around real daily use rather than a demo.

How would you describe the primary audience of your product?

Geniuz's answer:

Developers, AI power users, and teams who work with Claude every day โ€” people running Claude Desktop, Claude Code, Cursor, Windsurf, or their own agent frameworks who are tired of re-explaining their context each session. It's especially suited to fleet and agent operators coordinating multiple AI agents that need shared, persistent memory, and to anyone privacy-conscious who wants that memory to stay on their own machine.

Why should a person choose your product over its competitors?

Geniuz's answer:

Most memory tools are hosted services or developer SDKs you wire into code. Geniuz is local-first and zero-config: install it, run one command, and Claude Desktop has memory โ€” no account to create, no keys to manage, no data sent anywhere. It's open source under the MIT license and fully functional for free. If you value privacy, want to own your data, and want memory that works in the app you already use rather than a framework you have to build around, Geniuz is the simplest path.

What makes your product unique?

Geniuz's answer:

Geniuz runs entirely on your own machine. Memory is recalled by meaning, not keywords, through a semantic search model bundled right into the app โ€” no cloud, no account, no API keys, and nothing leaves your computer. It plugs into Claude Desktop through Anthropic's MCP standard with a single command, exposing just three tools: remember, recall, and recent. Memories survive session boundaries and context compaction, so your AI keeps the standards you set and the reasons behind your decisions instead of starting from zero every conversation.
