The official Model Context Protocol repository includes a memory reference server based on a knowledge graph. It is useful for learning how tools can give a model persistent context.
The repository also states that its reference servers are educational examples rather than production-ready solutions. That warning should stay attached whenever someone recommends the memory server for emotionally important data.
A working demo is not yet a dependable companion archive. Security boundaries, backups, conflict handling and deletion all need to be designed around the person using it.
If you want the platform details, they’re here.
