# Memex (MCP server)

> Memex is an MCP server that adds developer tools to AI assistants such as Claude Desktop, Claude Code and Cursor. Zettelkasten-based agent memory system with bidirectional links. It has 142 GitHub stars, is released under the MIT license and runs locally with npx -y @touchskyer/memex.

Persistent memory for AI coding agents. Your agent remembers what it learned across sessions. Every time your AI agent finishes a task, it saves insights as atomic knowledge cards with [[bidirectional links]]. Next session, it recalls relevant cards before starting work — building on what it already knows instead of starting from scratch.
