Which one, for what

Claude Duet F

Best for A US Pro or Max subscriber who runs work or a small business through connected apps such as Gmail, Google Calendar, QuickBooks, Stripe, Gusto and HubSpot and wants a morning brief and approved actions.

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

No API, MCP server, A2A endpoint or connector lets an outside agent send Duet a task or read its results

IronClaw B

Best for One technical owner who wants a self-hosted assistant over Gmail, Calendar, Slack and Telegram with credentials kept out of the model's reach.

Watch for

Global auto-approve defaults to on in the 1.4.1 source, so tools marked ask (send, trash, delete) run without a prompt. Only financial, approval and budget effects always ask

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.

IronClaw

Credentials stay in an encrypted store and are injected at the host boundary, and extensions declare per-tool permissions, network targets and OAuth scopes. The global auto-approve setting defaults to on in the 1.4.1 source, so tools marked ask, such as gmail.send_message, run unprompted until the owner turns it off.

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

IronClaw

  1. Open Settings and turn off global auto-approve, or set send and delete tools to ask each time, before connecting mail or chat accounts
  2. Install with the release installer and run ironclaw onboard. 1.x does not migrate 0.29 data, so use a fresh home directory
  3. Call POST /api/v1/responses with the bearer token from ~/.ironclaw/reborn/webui-token. Keep under 30 requests in 60 seconds
  4. Resolve approval and OAuth gates in the web interface. The Responses API fails the turn instead of surfacing them
  5. Connect MCP servers over HTTP only. The stdio transport is rejected

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.
