Claude Desktop installs Brain as a plugin from the `levirge/brain` GitHub
marketplace. Five steps, all in the app — no terminal. Brain is in early access with limited capacity — [request
access](/contact) first; the plugin connects the moment your workspace is
active.

## 1 · Open the plugin marketplace

In Claude Desktop, open **Settings → Plugins**, then click **Add → Add
marketplace**.

## 2 · Choose the marketplace source

Pick **Add from a repository** — the Levirge marketplace syncs straight
from GitHub.

![Add marketplace dialog offering Browse Anthropic sources or Add from a repository](/assets/desktop-marketplace-source.svg)

## 3 · Sync the marketplace

Paste the repo into the URL field and click **Sync**:

```
levirge/brain
```

![Add marketplace dialog with levirge/brain entered and the Sync button](/assets/desktop-add-marketplace-brain.svg)

## 4 · Enable the plugin

Click **Browse** to open the Directory, pick the **levirge-brain**
marketplace under **Code**, and click **+** on **Levirge Brain**.

## 5 · Done — Levirge Brain is installed

**Levirge Brain** now sits in your plugin list. It connects the MCP server
and adds the `/brain:*` commands; sign in with OAuth on first use —
workspace tokens remain as a fallback.
