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.

Zo Computer

Zo publishes an OpenAPI file, Markdown docs, plan prices and a named list of the providers that receive user content. One access token grants full access to the workspace, no approval step before sending or buying was found in the reviewed docs, and no status page, rate limit or SLA is published.

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

Zo Computer

  1. Send POST https://api.zo.computer/zo/ask with Authorization: Bearer zo_sk_... and an input string. The owner creates the token under Settings > Advanced
  2. Pass persona_id for a persona with a narrow tool set. The token itself carries every permission the owner has
  3. Set memory_mode to off to keep workspace memory out of a request. The field is in the OpenAPI file and absent from the API guide
  4. Do not retry /zo/ask blindly after a timeout. No idempotency key is documented and the request may already have sent a message
  5. Append .md to any guide or reference URL for Markdown

Other comparisons with Claude Duet or Zo Computer

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.
