const result = await mcp.call('send_email', {
from: 'admin@company.com',
to: ['user@company.com'],
subject: 'Welcome to our service!',
body: 'Your account is ready to use.',
body_type: 'plain'
});

await mcp.call('check_email_status', {
queue_id: result.email_details.queue_id
});
```
### Manage Domains
```typescript
// List all active domains
const domains = await mcp.call('list_domains', {
active_only: true
});
// Create new domain
await mcp.call('create_domain', {
domain: 'newclient.com',
description: 'New client domain',
quota: 5368709120 // 5GB
});
```
### Monitor System
```typescript
// Check server health
const health = await mcp.call('health_check');
// Get recent error logs
const errors = await mcp.call('get_error_logs', {
limit: 50,
