RA-OS Overview
What is RA-OS?
RA-OS is a minimal knowledge graph UI with MCP server integration. It provides a local-first knowledge management system designed to be extended by external AI agents via the Model Context Protocol.
Open Source: github.com/bradwmorris/ra-h_os
Design Philosophy
Local-first — Your knowledge network belongs to you. Everything runs locally in a SQLite database you control.
Agent-agnostic — No built-in AI chat. Instead, RA-OS exposes an MCP server that any AI agent (Claude Code, custom agents) can connect to.
Simple & focused — 2-panel UI for browsing and editing your knowledge graph. No bloat.
