ZenBrain Memory Overview

ZenBrain Memory is an MCP server for retaining agent memory across conversations through seven memory layers, including episodic, semantic, procedural, and core memory. It stores data locally in SQLite by default, requires no account, and makes no network calls of its own. The project also includes 20 tested memory algorithm modules covering mechanisms such as spaced repetition, emotional tagging, forgetting curves, and sleep replay. Reach for it when an agent needs self-hosted, cross-session memory in Claude Code, Claude Desktop, or Cursor.

Primary Use Cases for ZenBrain Memory:
  • Persist agent context across conversations
  • Store facts and procedures for later retrieval
  • Run self-hosted memory with a local SQLite database
  • Add layered memory to Claude Code or Cursor
