Getting Started

Step 1 — Create an account

Go to app.loombrain.com and sign in with Google OAuth or a magic link. No credit card required to start.

Step 2 — Install the CLI

Install via npm or Homebrew:

# npm
npm install -g @loombrain/cli

# Homebrew
brew install amentistudio/tap/lb

Then authenticate:

lb login

This opens a browser window and exchanges a token. Your credentials are stored locally in ~/.config/loombrain/.

Step 3 — Install the Chrome Extension

Install the LoomBrain extension from the Chrome Web Store. After installing, click the extension icon and sign in with the same account.

The extension adds a capture button to your browser toolbar and a right-click context menu item.

Step 4 — Connect the MCP Server

Add LoomBrain to Claude Code or Claude Desktop:

claude mcp add --transport http loombrain https://mcp.loombrain.com/mcp -s user

This registers the LoomBrain MCP server under the name loombrain. Claude will then have access to your knowledge graph as context during conversations.

See MCP Setup for authentication details and available tools.

Step 5 — Capture your first page

Via the extension: Navigate to any page and click the LoomBrain toolbar icon. Add an optional note explaining why you saved it, then click Capture.

Via the CLI:

lb capture https://example.com/some-article --why "reference for auth design"

The --why flag is optional but recommended — it improves auto-classification accuracy.

What happens next: The page is enqueued for processing. Within approximately one minute, it will be extracted, classified, linked to related nodes, and indexed for search. You can verify it appeared with:

lb search "example article"

Or open the dashboard to see it in your graph.
