An MCP server that lets coding agents build and query a persistent knowledge graph of concepts, architecture, and decisions, enabling them to remember across sessions.

Omega Stenographer MCP is the passive observation layer of the VERITAS & Sovereign Ecosystem (Omega Universe). Where Omega Brain enforces governance and VERITAS gates evaluate artifact integrity, Stenographer observes: it ingests every conversation turn, extracts decisions and blockers from agent reasoning, builds live running notes, and compresses stale context into searchable briefs before it ca

Enables persistent storage and semantic search of coding preferences, patterns, and implementations using Mem0, allowing AI agents to remember and retrieve development best practices across sessions.
