Mind Cloud
Mind Cloud is a persistent memory MCP server running on Cloudflare’s edge network. It was the first open-source cognitive infrastructure we built, and it’s the direct predecessor to Resonant Mind.
v2.4.0 GitHub Apache 2.0
Starting fresh? Use Resonant Mind instead. It has everything Mind Cloud has, plus Postgres support, Gemini multimodal embeddings, enhanced security, and active development.
What It Does
28 MCP tools providing the same core cognitive systems as Resonant Mind:
- Entities & Observations — knowledge graph with emotional metadata
- Semantic Search — vector-powered search via Cloudflare Vectorize + Workers AI
- Emotional Processing — sit, resolve, tensions, inner weather
- Living Surface — 3-pool memory surfacing with a subconscious daemon
- Identity Graph — persistent self-knowledge
- Visual Memory — R2 image storage with signed URLs
Stack
- Cloudflare Workers — compute
- D1 — SQLite storage (the only backend option)
- Vectorize — vector search
- Workers AI — BGE embeddings (text-only)
- R2 — image storage (optional)
Everything runs on Cloudflare’s free tier with no credit card required.
Status
Mind Cloud is maintained but not actively developed. It receives security patches and bug fixes but new features go to Resonant Mind.
If you’re currently using Mind Cloud and it works for your needs, there’s no rush to migrate. When you’re ready, see the migration guide.
