Every other memory system trusts. MMPM proves.
Self-hosted. Source available. Your data never leaves your infrastructure. The only credible open-source alternative to Mem0 and Zep — with production-grade observability baked in.
Merkle audit paths on every atom. Tamper-evident by design — table stakes for fintech, healthcare, and legal AI. Architecturally ahead of SOC 2 compliance patches.
The Markov transition layer learns what the agent needs next and pre-surfaces it with its own proof. 64% hit rate cold start. 0.032ms p95 proof verify. No competitor does this.
Every atom carries a cryptographic proof path verifiable against the current tree root. Tamper anything — the proof breaks.
Transition weights update on every access. On retrieval, the system returns the predicted next atom — complete with its own proof.
Every commit increments a monotonic version. Any read accepts asOfVersion or asOfMs — replay the exact memory state at any past moment.
Ships a full Model Context Protocol server. Agents in Claude Desktop read and write MMPM memory natively, no HTTP plumbing required.
quickstart
# one-line start docker-compose up # write an atom curl -X POST localhost:3000/atoms \ -d '{"atom":"v1.fact.user_prefers_dark_mode"}' # access + get Markov prediction curl -X POST localhost:3000/access \ -d '{"atom":"v1.fact.user_prefers_dark_mode"}' # → returns atom + predicted_next + proof.verified: true
