Server Noonien Overview

server-noonien provides a shared knowledge-graph memory layer for AI agents through MCP. It stores each node's changes in an append-only shard and merges shards using a CRDT, allowing replicas to converge without a central server or database. The MCP process runs over stdio, while the optional nooniend daemon synchronizes shards directly across machines over a LAN or VPN. Reach for it when agents need durable, structured memory across machines, including during offline operation.

Primary Use Cases for Server Noonien:
  • Store structured facts about users, projects, and tasks
  • Synchronize agent memory across LAN-connected machines
  • Search observations and entity metadata from an MCP client
  • Merge knowledge-graph entities after duplicate detection
