Score: 7.5/10 (Innovation: 7, Technical: 8, Documentation: 8, Utility: 7)

Myco Brain provides persistent, source-traceable memory for AI agents using self-hosted Postgres, with a trust model that compounds confidence from corroboration and never silently overwrites facts. Its novel combination of deterministic fact management, dynamic schema evolution, and MCP-native design addresses a real gap in agent memory reliability.
