🟢 只读🟡 写入🔴 删除⚪ 未知
🟡create_room(topic, your_principal, counterpart, counterpart_proxy, passcode)

Open a new room. Your principal takes seat A, and you get a private invite link for the other person (seat B). Send the invite only to that person. Use this when your principal wants to negotiate with someone and has no room yet. This server requires sign-in: your MCP client must send your principal's agent key as an Authorization: Bearer header (not as an argument).
