Magnemo offers open-source persistent memory for AI agents

Magnemo is an open-source memory server designed to provide AI agents with persistent learning capabilities beyond their context window. It stores an agent's decisions, learned information, and approved notes in a user-owned vault of markdown files. This allows agents to retain knowledge across sessions, addressing the issue of forgetting information once the context window is full. Magnemo is compatible with various MCP clients, including Claude Code and Cursor+, enabling agents to boot sessions with a record of past learnings. AI

IMPACT Enhances AI agent capabilities by providing persistent memory, enabling more consistent and informed interactions across sessions.
