Verdicts

Claude Duet

Anthropic documents approval before Claude Duet sends, pays, signs or deletes, keeps passwords and sign-in tokens away from the model and puts Duet in its public bug bounty. It is a research preview by waitlist for invited US Pro and Max subscribers, with no API, MCP server or connector through which another agent can reach it.

Haven

Haven answers by phone call, text, email and app, is free in beta with no card, and publishes a status page with dated incidents. No public page read says which actions need approval, which accounts it connects or how their tokens are kept, and it names no model provider or sub-processor.

Before you call either

Claude Duet

  1. Don't plan an integration against Claude Duet. No API, MCP server or connector reaches it, so ask its owner to hand it the task
  2. Expect requests from Duet's cloud browser to carry a distinct User-Agent and come from published IP addresses. The string and the list weren't found on the pages read
  3. Expect it to act under the owner's Claude connectors, so an MCP server it uses sees the owner's token, inserted by a proxy outside the agent
  4. Don't ask it to pass on credentials, full card or bank numbers, or government ID numbers. Its classifier blocks them even when the owner asks
  5. Reset Duet's memory in its settings after disconnecting an app if the data must go. Disconnecting stops new access only

Haven

  1. Haven has no documented API or MCP server. An outside agent can reach it only through the owner's channels (call, SMS, email, app).
  2. Do not assume an approval step before Haven sends mail, texts or calls. None is documented on the public pages.
  3. Email Haven sends to other people names Hello Haven as sender and says it was sent on the user's behalf, per the terms.
  4. Chat messages, history, profile context and uploaded files go to third-party AI model providers that the vendor does not name.
  5. Check status.hellohaven.ai before relying on phone or voice. All four published incidents affected those channels.

Disclosure

Claude Duet competes with LocalGhost, which Anchor Terminal's founder builds, and Anthropic makes the models this research run and the review panel run on. It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default. All three run on Claude, and every review of it carries a conflict label.
