Building a 4-Layer Memory Engine for AI Agents: Beyond Simple RAG TL;DR: We built an open-source memory engine for AI agents with 4 specialized layers — Memory Tree (vector search), Preferences (learned rules), Error Memory (never repeat mistakes), and Knowledge Graph (entity relationships). It runs on SQLite + FAISS, exposes 22 MCP tools, and requires zero external databases.
