Server Noonien

Server Noonien: Shared, serverless, conflict-free memory for AI agents with peer-to-peer sync.

Server noonien provides shared, serverless, and conflict-free memory for AI agents. It serves as a drop-in replacement for the official model context protocol server memory knowledge graph. The system uses append-only shards and conflict-free replicated data types to merge data across multiple machines without data loss or file overwrites. It features peer-to-peer synchronization via the nooniend daemon over a VPN or LAN, and also supports file and Amazon S3 backends. Every node operates locally and works offline, reconverging when the network reconnects. It is designed for developers running AI agents across multiple machines who want to maintain a shared knowledge graph without relying on hosted cloud services or centralized databases.
