const tools = await getAllMcpTools([mcpServer]);
new RealtimeAgent({ tools: [...existingTools, ...tools] });

Proposed Solution

Add mcpServers to RealtimeAgentConfiguration:
type RealtimeAgentConfiguration = {
  // ...existing properties
  mcpServers?: MCPServer[];
}

This would allow:
new RealtimeAgent({
  name: 'Agent',
  mcpServers: [mcpServer], // Automatic tool expansion
  voice: 'alloy'
});

Benefits

- Consistency with regular Agent API
- Simpler code
- Better developer experience
