Memory

npx -y @modelcontextprotocol/server-memory

The Memory server stores facts as a local knowledge graph — entities, relationships, observations — that persists between sessions, giving an agent a lightweight, inspectable form of long-term memory.

Why it matters

Without persistence, every new conversation starts with zero context about you, your preferences, or past decisions. A local, file-backed memory store closes that gap without relying on a specific vendor’s built-in memory feature.

Good for

Personal assistants and long-running projects where an agent benefits from remembering user preferences, past decisions, or project facts across many separate sessions.
