What is the Yourmemory MCP server?

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.

The short version

Every morning your AI agent treats you like a stranger. Same context re-explained. Same preferences forgotten. Every session starts from zero.

What it needs from you

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.

Getting it running

yourmemory on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.

How it compares

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.

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

Frequently asked questions

It connects Yourmemory to MCP-compatible AI assistants such as Claude and Cursor. Instead of copying data back and forth by hand, the assistant works with Yourmemory directly.
