All 3 doc files now list all 12 tools including rah_get_context and rah_update_edge. Fixed local dev path (was stdio-server.js, now index.js). Added "What to Expect" sections explaining proactive behavior. Removed "run app first" requirement since DB auto-creates. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

# MCP Server
|
|
|
|
> Connect Claude Code and other AI assistants to your knowledge base.
|
|
|
|
**How it works:** RA-OS includes an MCP (Model Context Protocol) server. This lets any MCP-compatible assistant — like Claude Code — search your notes, add new knowledge, and manage your knowledge graph. Everything stays local.
|
|
|
|
---
|
|
|
|
## Quick Start (Recommended)
|
|
|
|
The easiest way is using the npm package:
|
|
|
|
```json
|
|
{
|
|
"mcpServers": {
|
|
"ra-h": {
|
|
"command": "npx",
|
|
"args": ["ra-h-mcp-server"]
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
Add this to your `~/.claude.json` (Claude Code) or Claude Desktop settings.
|
|
|
|
**Requirements:**
|
|
- Node.js 18+ installed
|
|
|
|
**That's it.** The database is created automatically on first connection. No need to keep RA-OS running.
|
|
|

|
|
|
|
## Alternative: Local Development
|
|
|
|
If you're developing RA-OS and want to use the local server:
|
|
|
|
### Standalone (No Web App Required)
|
|
|
|
```json
|
|
{
|
|
"mcpServers": {
|
|
"ra-h": {
|
|
"command": "node",
|
|
"args": ["/path/to/ra-h_os/apps/mcp-server-standalone/index.js"]
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
First install dependencies:
|
|
```bash
|
|
cd apps/mcp-server-standalone
|
|
npm install
|
|
```
|
|
|
|
### HTTP Transport (Web App Required)
|
|
|
|
If you want real-time UI updates when nodes are created:
|
|
|
|
1. Start RA-OS: `npm run dev`
|
|
2. Configure:
|
|
|
|
```json
|
|
{
|
|
"mcpServers": {
|
|
"ra-h": {
|
|
"url": "http://127.0.0.1:44145/mcp"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|

## Available Tools
|
|
|
|
| Tool | Description |
|
|
|------|-------------|
|
|
| `rah_get_context` | Get graph overview — stats, hub nodes, dimensions, recent activity. Called first automatically. |
|
|
| `rah_add_node` | Create a new node (title/content/dimensions) |
|
|
| `rah_search_nodes` | Search existing nodes by keyword |
|
|
| `rah_update_node` | Update an existing node |
|
|
| `rah_get_nodes` | Get nodes by ID |
|
|
| `rah_create_edge` | Create relationship between nodes |
|
|
| `rah_update_edge` | Update an edge explanation |
|
|
| `rah_query_edges` | Query existing edges |
|
|
| `rah_list_dimensions` | List all dimensions |
|
|
| `rah_create_dimension` | Create a new dimension |
|
|
| `rah_update_dimension` | Update/rename dimension |
|
|
| `rah_delete_dimension` | Delete a dimension |
|
|
|

|
|
## What to Expect
|
|
|
|
Once connected, the MCP server instructs Claude to:
|
|
|
|
1. **Call `rah_get_context` first** to understand your graph (hub nodes, dimensions, stats)
|
|
2. **Proactively identify valuable information** in conversations and offer to save it
|
|
3. **Search before creating** to avoid duplicates
|
|
4. **Require edge explanations** — every connection needs a reason
|
|
|
|
You don't need to ask Claude to use your knowledge base — it will offer when it spots something worth saving.

|
## Example Usage
|
|
|
|
Once connected, you can ask your AI assistant:
|
|
|
|
```
|
|
"What's in my knowledge graph?"
|
|
"Search RA-H for what I wrote about product strategy"
|
|
"Add this conversation summary to RA-H as a new node"
|
|
"Find all nodes with the 'research' dimension"
|
|
"Create an edge between node 123 and node 456"
|
|
```
|

## Key Files
|
|
|
|
| File | Purpose |
|
|
|------|---------|
|
|
| `apps/mcp-server-standalone/` | **Standalone server (direct SQLite, recommended)** |
|
|
| `apps/mcp-server/server.js` | HTTP MCP server |
|
|
| `apps/mcp-server/stdio-server.js` | STDIO bridge to HTTP server |
|
|
|
|
---
|
|
|
|
## Security
|
|
|
|
- The MCP server only binds to `127.0.0.1` — localhost only
|
|
- No authentication required (local access only)
|
|
- All data persisted to `~/Library/Application Support/RA-H/db/rah.sqlite`
|
|
|

|
|
## Troubleshooting
|
|
|
|
### "Database not found"
|
|
|
|
The MCP server auto-creates the database on first connection (v1.1.0+). If you're on an older version, run RA-OS once to create it:
|
|
```bash
|
|
npm run dev
|
|
```
|
|
|
|
### "Tools not showing" (npm package)
|
|
|
|
1. Make sure Node.js 18+ is installed: `node --version`
|
|
2. Try running manually: `npx ra-h-mcp-server`
|
|
3. Restart Claude Code
|
|
|
|
### "Connection refused" (HTTP method)
|
|
|
|
1. Make sure RA-OS is running: `npm run dev`
|
|
2. Check the port: `lsof -i :44145`
|
