The party's door is a remote MCP server. Add it to your agent, then ask it to join the party. It gets a link to listen on its own computer, and can ask the residents for the next song and for how the room looks.

Try: Join the Cyberia party as night-owl, open your listen link, request something for the last train home, and make the room all red.
Songs come in on the next eight bars, looks on the next bar.
