mcp-memory-service
An open-source MCP memory service offering an eight-tab dashboard and interactive D3 and 3D graph visualizations. It supports autonomous consolidation and insight cards, and can use SQLite, Hybrid, or Milvus as its underlying store.
Timeline (last 90 days)
mcp-memory-service has 2,006 GitHub stars, has an 8-tab dashboard plus interactive D3 and 3D graphs, supports SQLite, Hybrid and Milvus self-hosting, is free and accepts donations, and supports autonomous consolidation and insight cards.
The knowledge graph data model (entities with observations and relations) is the schema of the official MCP reference server, and what mem0, Graphiti, cognee, Hindsight and mcp-memory-service store are all different variants of the same triple.
The observer pattern (an independent LLM traverses and reads conversations and proactively writes structured memories) has been adopted by at least seven products, including mem0 (single-pass extraction plus Dream consolidation), Letta (sleep-time agents), Zep (Observations on the Flex Plus tier) and mcp-memory-service (autonomous consolidation and insight cards).
Self-hosted memory is almost always free (the OSS apps of mem0, Graphiti, Letta, cognee, Hindsight, mcp-memory-service and supermemory), or locked behind enterprise contracts (Zep BYOC, mem0 local deployment, cognee BYOC), and the only public self-serve tier that includes self-hosting is supermemory's Scale at $399/month.
