# 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** — 2-panel 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
- 2-panel UI (nodes list + focus panel)
- Node/Edge/Dimension CRUD
- Full-text and semantic search
- MCP server with 14 tools
- Guides system (context for 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 │ • Dimensions │
│ │ │
└─────────────┴─────────────────────────┘
```
## MCP Integration
RA-OS is designed to be the knowledge backend for your AI workflows:
```json
{
"mcpServers": {
"ra-h": {
"command": "npx",
"args": ["ra-h-mcp-server"]
}
}
}
```
Add this to `~/.claude.json` and restart Claude. Works without RA-OS running.
Available tools: `rah_add_node`, `rah_search_nodes`, `rah_update_node`, `rah_get_nodes`, `rah_create_edge`, `rah_query_edges`, `rah_list_dimensions`, `rah_create_dimension`, `rah_update_dimension`, `rah_delete_dimension`
