Best For

Contract is available with explicit auth and schema references.

Not Ideal For

ra-h-open-source is not ideal for teams that need stronger public trust telemetry, lower setup complexity, or more explicit contract coverage before production rollout.

Setup snapshot

git clone https://github.com/bradwmorris/ra-h_os.git

1
Setup complexity is MEDIUM. Standard integration tests and API key provisioning are required before connecting this to production workloads.
2
Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

TL;DR: Clone this repository and you'll have a local SQLite database on your computer. The database schema is structured so external AI agents can continuously read and write to it, building your knowledge graph externally.

Currently macOS only. Linux and Windows support is coming. If you want to run it on Linux/Windows now, see instructions at the bottom.

Full documentation: ra-h.app/docs/open-source

What This Does

Stores knowledge locally — Notes, bookmarks, ideas, research in a SQLite database on your machine
Provides a UI — Browse, search, and organize your nodes at localhost:3000
Exposes an MCP server — Claude Code, Cursor, or any MCP client can query and add to your knowledge base

Your data stays on your machine. Nothing is sent anywhere unless you configure an API key.

Requirements

Node.js 20.18.1+ — nodejs.org
macOS — Works out of the box
Linux/Windows — Requires building sqlite-vec manually (see below)

Install

git clone https://github.com/bradwmorris/ra-h_os.git
cd ra-h_os
npm install
npm rebuild better-sqlite3
./scripts/dev/bootstrap-local.sh
npm run dev

Open localhost:3000. Done.

OpenAI API Key

Optional but recommended. Without a key, you can still create and organize nodes manually.

With a key, you get:

Auto-generated descriptions when you add nodes
Automatic dimension/tag assignment
Semantic search (find similar content, not just keyword matches)

Cost: Less than $0.10/day for heavy use. Most users spend $1-2/month.

Setup: The app will prompt you on first launch, or go to Settings → API Keys.

Get a key at platform.openai.com/api-keys

Where Your Data Lives

~/Library/Application Support/RA-H/db/rah.sqlite   # macOS
~/.local/share/RA-H/db/rah.sqlite                  # Linux
%APPDATA%/RA-H/db/rah.sqlite                       # Windows

This is a standard SQLite file. You can:

Back it up by copying the file
Query it directly with sqlite3 or any SQLite tool
Move it between machines

Connect Claude Code (or other MCP clients)

Add to your ~/.claude.json:

{
  "mcpServers": {
    "ra-h": {
      "command": "npx",
      "args": ["ra-h-mcp-server"]
    }
  }
}

Restart Claude Code fully (Cmd+Q on Mac, not just closing the window).

Verify it worked: Ask Claude "Do you have rah_ tools available?" — you should see tools like rah_add_node, rah_search_nodes, etc.

For contributors testing local changes, use the local path instead:

{
  "mcpServers": {
    "ra-h": {
      "command": "node",
      "args": ["/absolute/path/to/ra-h_os/apps/mcp-server-standalone/index.js"]
    }
  }
}

What happens: Once connected, Claude calls rah_get_context first to orient itself (stats, hub nodes, dimensions, available guides). It proactively captures 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. For complex tasks it reads guides to understand your graph conventions and custom workflows.

Available tools:

| Tool | What it does | |------|--------------| | rah_get_context | Get graph overview — stats, hub nodes, dimensions, recent activity | | rah_search_nodes | Find nodes by keyword | | rah_add_node | Create a new node | | rah_get_nodes | Fetch nodes by ID | | rah_update_node | Edit an existing node | | rah_create_edge | Link two nodes together | | rah_update_edge | Update an edge explanation | | rah_query_edges | Find connections | | rah_list_dimensions | List all tags/categories | | rah_create_dimension | Create a new dimension | | rah_update_dimension | Update/rename a dimension | | rah_delete_dimension | Delete a dimension | | rah_list_guides | List available guides (system + custom) | | rah_read_guide | Read a guide by name | | rah_write_guide | Create or update a custom guide | | rah_delete_guide | Delete a custom guide | | rah_search_content | Search through source content (transcripts, books, articles) | | rah_sqlite_query | Run read-only SQL queries (SELECT/WITH/PRAGMA) |

Example prompts for Claude Code:

"What's in my knowledge graph?"
"Search my knowledge base for notes about React performance"
"Add a node about the article I just read on transformers"
"What nodes are connected to my 'research' dimension?"

Direct Database Access

Query your database directly:

# Open the database
sqlite3 ~/Library/Application\ Support/RA-H/db/rah.sqlite

# List all nodes
SELECT id, title, created_at FROM nodes ORDER BY created_at DESC LIMIT 10;

# Search by title
SELECT title, description FROM nodes WHERE title LIKE '%react%';

# Find connections
SELECT n1.title, e.explanation, n2.title
FROM edges e
JOIN nodes n1 ON e.from_node_id = n1.id
JOIN nodes n2 ON e.to_node_id = n2.id
LIMIT 10;

See ra-h.app/docs/open-source for full schema documentation.

Commands

| Command | What it does | |---------|--------------| | npm run dev | Start the app at localhost:3000 | | npm run build | Production build | | npm run type-check | Check TypeScript |

Linux/Windows

The repo ships with a macOS binary for sqlite-vec (vendor/sqlite-extensions/vec0.dylib). On Linux or Windows you need to swap it for your platform's version.

Linux:

Go to sqlite-vec releases
Download the release matching your architecture (e.g. sqlite-vec-0.1.6-loadable-linux-x86_64.tar.gz)
Extract vec0.so from the archive
Copy it to vendor/sqlite-extensions/vec0.so in this repo
Run the normal install steps above

Windows:

Go to sqlite-vec releases
Download the Windows release (e.g. sqlite-vec-0.1.6-loadable-windows-x86_64.zip)
Extract vec0.dll from the archive
Copy it to vendor/sqlite-extensions/vec0.dll in this repo
Run the normal install steps above

Without sqlite-vec, everything works except semantic/vector search.
