Developer builds self-hosted AI 'second brain' with local LLM and MCP

By PulseAugur Editorial · [1 sources] ·

A developer has created a self-hosted "second brain" application called Brain AI Hub, designed to preserve context from AI chat sessions and notes. The tool integrates a local LLM (Ollama with Qwen2.5 and Nomic-Embed), an Obsidian-style markdown vault, and semantic search capabilities. It also features an agent bridge using MCP (Message Communication Protocol) servers to connect with IDEs like Cursor and Claude Code, allowing agents to access local data without sending it to third-party APIs.

IMPACT Enables developers to maintain persistent context and local data access for AI agents, reducing reliance on cloud services.

    Self-hosted second brain with MCP

    <p>I run IT and cybersecurity ops by day and tinker in a homelab at night. The problem I kept hitting: useful context from Cursor and Claude Code sessions evaporates when the chat ends. Notes end up scattered. RAG demos are cloud-first. I wanted something I own.</p> <p>So I built…
