Containarium MCP Server

How to use Containarium MCP Server

That installs Containarium + Incus + dependencies, starts the daemon,
and gives you a working API at `http://localhost:8080`.

### 2. Create your first box

```bash
sudo containarium create alice --ssh-key ~/.ssh/id_ed25519.pub
sudo containarium list
```

### 3. Wire up SSH so `ssh alice` just works

```bash
containarium ssh-config sync
# Adds entries to ~/.containarium/ssh_config.
# Then add ONE line to ~/.ssh/config:
#     Include ~/.containarium/ssh_config
ssh alice  # connects through the sentinel
```

### 4. Point your agent at the box

In `~/.cursor/mcp.json` or `~/.claude.json`:

```jsonc
{
  "mcpServers": {
    "containarium-box": {
      "command": "ssh",
      "args": ["alice", "agent-box"]
    }
  }
}
