> **Manage your AI agent's knowledge — parse, store, query, and collaborate.**

KGN is a developer-friendly CLI + MCP server for teams building with AI agents.
Write knowledge nodes in simple YAML+Markdown files (`.kgn`), define relationships
between them (`.kge`), and let KGN handle storage, similarity search, conflict
detection, and multi-agent task handoffs — all backed by PostgreSQL + pgvector.

**Hybrid architecture:** PostgreSQL is the local working engine; GitHub is the
long-term source of truth. Export, commit, and push in one command.
