This is a disclosed memory plugin, but it handles conversation data with too little containment around automatic sending, storage, logging, and unauthenticated server access.
Install only if you deliberately want a long-term memory system that may send conversation text to a local API and retain it. Keep the server bound to localhost or firewalled, do not expose it to shared networks without authentication, avoid storing secrets or sensitive personal data, review and pin server dependencies, and periodically clear both stored memories and ~/.openclaw/logs/memory-enhancement.log.
