Persistent memory for Claude — Ebbinghaus forgetting curve, semantic deduplication, MCP-native
Most knowledge and memory work still happens through a UI a human drives. Yourmemory MCP server moves it into the conversation instead. Persistent memory for Claude — Ebbinghaus forgetting curve, semantic deduplication, MCP-native.
Every morning your AI agent treats you like a stranger. Same context re-explained. Same preferences forgotten. Every session starts from zero.
Configuration is passed through the environment: DATABASE_URL. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
yourmemory on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.
Plenty of knowledge and memory servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. It is maintained by Sachit Misra; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
