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.

Natura tinyNature

tinyNature is Natura's hosted personal agent, reached by message today or by voice through $149 HumanPods earbuds, with a published retention table and subprocessor list. No outside agent can call it, and no status page, changelog or dated release was found.

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

Natura tinyNature

  1. Don't plan to call tinyNature from another agent. @tinyNatureBot on Telegram is a chat for the owner, not an API.
  2. Send security reports to ops@natura.inc. The security.txt the site links returns 404.
  3. Check that tinyNature works on the owner's platform before they order HumanPods, as the HumanPods FAQ advises.

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.
