Claude Desktop

Install this extension to let Claude search your Fractal account, read notes, create and edit content, and save bookmarks for later.

What you can do

• Search your Fractal account
• Read documents
• Create, update, move, and delete nodes
• Save bookmarks
• Connect multiple Fractal accounts

What you need

• Claude Desktop on macOS or Windows
• A Fractal API key from fractal.io/api-key
• The latest .mcpb bundle from GitHub Releases

How to install

1. Download the latest .mcpb file from GitHub Releases.
2. Fully quit Claude Desktop.
3. Double-click the .mcpb file.
4. Approve the install prompt in Claude Desktop.
5. Paste your Fractal API key when prompted.
6. Reopen Claude Desktop if needed.

After installation, the Fractal tools should be available in Claude Desktop conversations.

Connect multiple accounts

You can connect more than one Fractal account by entering multiple API keys in the extension settings.

Recommended format:

Personal: key1, Work: key2

Use labels that are easy to refer to in conversation, such as Personal and Work. The first account becomes the default account.

Example prompts

• Search Fractal for "quarterly planning".
• Open my project notes bookmark and summarize the open tasks.
• Add "Review roadmap" and "Reply to vendor" to my Fractal today list.

Troubleshooting

• If Claude Desktop does not show the tools right away, fully quit and reopen the app.
• If your Claude Team or Enterprise workspace uses an extension allowlist, an admin may need to approve the extension first.
• If an account is missing, reopen the extension settings and check the API key format.
• If search results look stale, ask Claude to sync the results.
