MCP Memory Server
Reference MCP server that gives an agent a persistent knowledge graph — entities, relations, observations stored to disk and surfaced back across sessions. The simplest path to making an agent remember context between conversations without standing up a real vector store; an entry-tier alternative to Zep / Graphiti.

Alternatives
- Alternative toMem0 (agent memory API)
MCP Memory is JSON-on-disk knowledge-graph memory — entry-tier. Mem0 is a richer drop-in API. Pick MCP Memory for trivial setup; Mem0 for production-grade memory.
Pros
- Persistent agent memory in one server install
- Knowledge-graph shape (entities + relations) not just blobs
- Reference-grade simplicity
Cons
- JSON-on-disk storage — not for production-scale memory
- No semantic search, only graph traversal
- No multi-agent isolation
