Memory

cortexmd is an open-source long-term memory and code-navigation brain for AI agents, exposed over the Model Context Protocol. It gives an agent a persistent memory that survives across sessions and a way to navigate a codebase by querying an index instead of reading whole files into context. Self-hosted, MIT licensed, pre-alpha.

How cortexmd gives an AI agent a memory that behaves like one: eight kinds of memory, a hot/warm/cold lifecycle that promotes what you touch and lets the rest cool, hybrid recall that fuses keyword and meaning, a session-start wakeup, and a scheduled dream that quietly tidies the brain while nobody is looking.

A capable coding agent forgets everything when a session ends and re-reads the same files every time, burning tokens. This is the story of how a private homelab MCP server grew two answers to those problems and became cortexmd, the first post in a four-part series.
