DEV Community: Second Me

Second Me Now Supports MCP Protocol —— Your AI Identity Can Now Be Called Anywhere

Second Me — Tue, 22 Apr 2025 06:53:22 +0000

In just three weeks since open-sourcing, Second Me has surpassed 🌟 10,000 stars on GitHub, becoming one of the fastest-growing AI open-source projects of 2025. This milestone reflects the global community’s deep interest in AI-native identity systems — and hints at the early arrival of a new internet era built around personalized, autonomous agents.

Today, we’re excited to announce one of the most significant updates yet:

🌐 Second Me Now Supports the MCP Protocol: Your AI Identity, Callable Anywhere

This release introduces MCP Protocol Integration, enabling every Second Me instance to become a service-level AI personality interface that can be embedded into any compatible application or multi-agent system.

🔧 Key Capabilities

MCP Server Interface Expose your trained Second Me as a callable service with metadata like identity description, availability status, and unique instance ID — accessible by any MCP client, including Claude, GPTs, Zapier, Cursor, and more.
Plug-and-Play AI Personality in Any Workflow Second Me can now be used as a module in various AI apps and automation platforms. Deploy once, integrate everywhere.
Personalized AI Interactions Instead of generic models, systems now call your Second Me — with its unique way of thinking, long-term memory, and emotional context. The result is more coherent, personalized, and human-like interaction.

🚀 Other Notable Updates

Low-Data Mode & Multi-threading: Faster training with fewer resources
DPO (Direct Preference Optimization): Train Second Me to better reflect your personal values
Support for Huggingface API: More flexible model configurations
Fully Revamped Documentation: Improved onboarding across macOS, Windows, and Linux

🔭 What’s Next: The Future of AI Identity

As we move forward, our roadmap focuses on:

Expanding identity interface capabilities
Enhancing reasoning and lifelong learning
Lightweight local deployment options
Seamless integration with a broader range of tools and platforms

Second Me isn’t just an AI tool — it’s a foundation for a new kind of digital self: private, local, and truly yours. We're building toward a future where AI doesn’t just assist you — it represents you.

Let’s shape this future together.

Our Vision

Companies like OpenAI built "Super AI" that threatens human independence. We crave individuality: AI that amplifies, not erases, YOU.

We’re challenging that with "Second Me": an open-source prototype where you craft your own AI self—a new AI species that preserves you, delivers your context, and defends your interests.

It’s locally trained and hosted—your data, your control—yet globally connected, scaling your intelligence across an AI network. Beyond that, it’s your AI identity interface—a bold standard linking your AI to the world, sparks collaboration among AI selves, and builds tomorrow’s truly native AI apps.

Second Me: Create New AI Species to Combat OpenAI

Second Me — Thu, 20 Mar 2025 02:32:01 +0000

Companies like OpenAI built "centralized AI" — a centralized superintelligence that erodes human independence. We need individuality: tools that amplify, not erase, the irreplaceable "Me".

That's why we're building a new ecosystem to challenge centralized AI models, and we're sharing its open-source prototype, "Second Me" with you: a platform where you can build your independent AI self that can interact autonomously with other human-made AIs.

Sounds abstract? Let's take a closer look at Why Second Me.

1. Train your Second Me, your AI Identity gateway

Start training your AI self today and experience conversations that feel more authentic than ever. This is powered by our two revolutionary technologies:

HMM-Hierarchical Memory Modeling

We’ve pioneered AI memory with a three-layer (L0- L2) hierarchical structure, progressing from local to global, concrete to parameterized. This allows your AI self to rapidly recognize patterns, adapt, and evolve alongside you.

The Me-alignment Structure

Me-alignment is a cutting-edge system that transforms scattered user data into deeply personalized AI insights. Using advanced reinforcement learning, it ensures your AI self truly understands your unique preferences, behaviors, and decision-making patterns.
Our model outperforms the market’s leading Retrieval-Augmented Generation, GraphRag (1.0.1), by 37% in user understanding.

2. Scale your intelligence with your Second "ME"

Ever feel spread too thin? Imagine having a counterpart to ease your worries.
Try dispatching your AI self with different personas to interact just like you.

From filling out forms to booking hotels to batch-writing product documentation, your Second Me will soon handle these tasks seamlessly.

3. Build a network of Second me, exchange wisdom, foster deeper connections, or more

Building your AI self is just the beginning. We have prepared an entirely new world:

Let us introduce SMP(Second Me Protocol), a decentralized AI framework that enables independent AI entities to interact. Unlike traditional AI models, each "self" maintains full independence while securely communicating with others in a peer-to-peer network—fostering a dynamic, interconnected web of knowledge.

We envision a future where apps built on this protocol will redefine possibilities. To get you started, we've already developed a few innovative examples! Whether it’s collaborating with other AIs to spark creative solutions (see AI Space) or linking with others’ AI entities to form meaningful connections (see Second Tinder), the potential is limitless.

4. 100% Privacy

To counter "centralized Models", we must preserve absolute privacy. Second Me can run locally, so you stay in complete control of your personal data, sharing it only with your explicit permission. Meanwhile, AI entities form a decentralized network—each isolated but mutually accessible. Communication happens peer-to-peer, keeping you firmly in charge of your information.

Join us in building a future where every "me" matters.
