How do I use Voicebox MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Voicebox MCP Server say 'Hello everyone' using Zundamon (speaker 3)" That's it!
