This is duet's hosted MCP server: the duet panel for claude.ai, the Claude apps and ChatGPT. Add https://mcp-duet.gaioz.online/mcp as a custom connector; steps on the duet website.
It keeps no accounts and stores nothing on disk. Room codes are hashed as soon as a panel joins; messages stay in memory only while the panel is open. A request reaches your agent only when you click Hand to agent, and nothing guards what the agent does with it.
