# RA-H MCP Server
|
|
|
|
Connect Claude Code and Claude Desktop to your RA-H knowledge base. Direct SQLite access - works without the RA-H app running.
|
|
|
|
## Install
|
|
|
|
```bash
|
|
npx ra-h-mcp-server
|
|
```
|
|
|
|
That's it. No manual setup required.
|
|
|
|
## Configure Claude Code / Claude Desktop
|
|
|
|
Add to your Claude config (`~/.claude.json` or Claude Desktop settings):
|
|
|
|
```json
|
|
{
|
|
"mcpServers": {
|
|
"ra-h": {
|
|
"command": "npx",
|
|
"args": ["ra-h-mcp-server"]
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
Restart Claude. Done.
|
|
|
|
## Requirements
|
|
|
|
- Node.js 18+
|
|
- Database is created automatically at `~/Library/Application Support/RA-H/db/rah.sqlite` on first connection
|
|
|
|
## Environment Variables
|
|
|
|
| Variable | Default | Description |
|
|
|----------|---------|-------------|
|
|
| `RAH_DB_PATH` | ~/Library/Application Support/RA-H/db/rah.sqlite | Database path |
|
|
|
|
## What to Expect
|
|
|
|
Once connected, Claude will:
|
|
- **Call `getContext` first** to orient itself (stats, hub nodes, dimensions, skills)
|
|
- **Proactively capture knowledge** — when a new insight, decision, person, or reference surfaces, it proposes a specific node (title, dimensions, description) so you can approve with minimal friction
|
|
- **Read skills for complex tasks** — skills are editable and shared across internal + external agents
|
|
- **Search before creating** to avoid duplicates
|
|
|
|
## Available Tools
|
|
|
|
| Tool | Description |
|
|
|------|-------------|
|
|
| `getContext` | Get graph overview — stats, hub nodes, dimensions, recent activity |
|
|
| `createNode` | Create a new node |
|
|
| `queryNodes` | Search nodes by keyword |
|
|
| `getNodesById` | Load nodes by ID (includes chunk + metadata) |
|
|
| `updateNode` | Update an existing node |
|
|
| `createEdge` | Create connection between nodes |
|
|
| `updateEdge` | Update an edge explanation |
|
|
| `queryEdge` | Find edges for a node |
|
|
| `queryDimensions` | List all dimensions |
|
|
| `createDimension` | Create a dimension |
|
|
| `updateDimension` | Update/rename a dimension |
|
|
| `deleteDimension` | Delete a dimension |
|
|
| `listSkills` | List available skills |
|
|
| `readSkill` | Read a skill by name |
|
|
| `writeSkill` | Create or update a skill |
|
|
| `deleteSkill` | Delete a skill |
|
|
| `searchContentEmbeddings` | Search through source content (transcripts, books, articles) |
|
|
| `sqliteQuery` | Execute read-only SQL queries (SELECT/WITH/PRAGMA) |
|
|
|
|
## Skills
|
|
|
|
Skills are detailed instruction sets that teach agents how to work with your knowledge base. The default seeded skills are editable and shared by internal + external agents.
|
|
|
|
Skills are stored at `~/Library/Application Support/RA-H/skills/` and shared with the main app.
|
|
|
|
## What's NOT Included
|
|
|
|
This is a lightweight CRUD server. Advanced features are handled by the main app:
|
|
|
|
- Embedding generation
|
|
- AI-powered edge inference
|
|
- Content extraction (URL, YouTube, PDF)
|
|
- Real-time SSE events
|
|
|
|
## Testing
|
|
|
|
```bash
|
|
# Test database connection
|
|
node -e "const {initDatabase,query}=require('./services/sqlite-client');initDatabase();console.log(query('SELECT COUNT(*) as c FROM nodes')[0].c,'nodes')"
|
|
|
|
# Run the server
|
|
node index.js
|
|
```
