Unlike the cloud-based original, this version runs entirely on your machine with no external API costs. Features - Local-first : Everything runs on your machine, no cloud dependencies - Semantic search : Find thoughts by meaning, not just keywords - MCP integration : Accessible from Claude Code, Claude Desktop, and other MCP clients - Fast : 50-100ms to capture a thought, instant search - Private : Your data never leaves your computer - Zero cost : No API fees, completely free to run Architecture - Storage : SQLite + sqlite-vec (single-file vector database) - Embeddings : sentence-transformers with all-MiniLM-L6-v2 (384-dim, 22M params) - Capture : CLI command ( brain add \"thought\" ) - Retrieval : Local MCP server exposing tools to AI clients - Language : Python 3.10+ Installation 1. Install Dependencies Note : First run will download 90MB embedding model from HuggingFace (cached for future use). 2. Initialize Database This creates the SQLite database at data/brain.db . 3. Configure MCP Client To use OpenBrain from Claude Code, register it as a user-scoped MCP server: Then restart Claude Code to load the MCP server. Usage CLI Commands Add a thought: List recent thoughts: Search semantically: View statistics: Shell Alias Setup Add to your /.bashrc or /.zshrc to use brain from anywhere: MCP Tools (from Claude) Once the MCP server is configured, you can use these too","default_branch":null,"files":null,"tree":[],"storefront":"/r/Sneezembop","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/Sneezembop/openbrain/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
