# 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](https://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** — A compact multi-pane UI for browsing and editing your knowledge graph. No bloat.
|
|
|
|
## Tech Stack
|
|
|
|
- **Frontend:** Next.js 15, TypeScript, Tailwind CSS
|
|
- **Database:** SQLite + sqlite-vec (vector search)
|
|
- **Embeddings:** OpenAI (BYO API key)
|
|
- **MCP Server:** Local connector for Claude Code and external agents
|
|
|
|
## What's Included
|
|
|
|
- Multi-pane UI for nodes, contexts, map, table, and focus work
|
|
- Node/Edge CRUD with optional contexts
|
|
- Full-text and semantic search
|
|
- MCP server with graph and skill tools
|
|
- Skills system (shared instructions for internal + external agents)
|
|
- PDF extraction
|
|
- Graph visualization (Map view)
|
|
- BYO API keys
|
|
|
|
## What's NOT Included
|
|
|
|
- Chat interface (use external agents via MCP)
|
|
- Voice features
|
|
- Built-in AI agents
|
|
- Auth/subscription system
|
|
- Desktop packaging
|
|
|
|
## Two-Panel Layout
|
|
|
|
```
|
|
┌─────────────┬─────────────────────────┐
|
|
│ NODES │ FOCUS │
|
|
│ Panel │ Panel │
|
|
│ │ │
|
|
│ • Search │ • Node content │
|
|
│ • Filters │ • Connections │
|
|
│ • List │ • Context + metadata │
|

|
## MCP Integration
|
|
|
|
RA-OS is designed to be the knowledge backend for your AI workflows:
|
|
|
|
```json
|
|
{
|
|
"mcpServers": {
|
|
"ra-h": {
|
|
"command": "npx",
|
|
"args": ["--yes", "ra-h-mcp-server@2.1.2"]
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
Add this to `~/.claude.json` and restart Claude. Run RA-H once first so the database exists. The standalone MCP server can write nodes without the app running, but the app owns chunking and embedding from node source. If you publish a newer MCP release and need clients to pick it up immediately, bump the pinned version here and restart the client.
|
|
|
|
Core tools include: `queryNodes`, `retrieveQueryContext`, `createNode`, `writeContext`, `updateNode`, `getNodesById`, `createEdge`, `updateEdge`, `queryEdge`, `queryContexts`, `listSkills`, `readSkill`
