The short answer

Can Claude Duet manage your social media?

Yes, through a connector.

Claude Duet does not post to social media on its own. Antwork is a Model Context Protocol (MCP) connector you add once at claude.ai as a custom connector, which Duet then uses. You connect each account once on that platform's own login screen, and from then on Claude Duet drafts, schedules and publishes to LinkedIn, X (Twitter), Instagram, Threads, TikTok, YouTube, Facebook, Pinterest, Bluesky, Discord, Mastodon and Telegram from the conversation, through each platform's official API.

  • 12 platforms, one connectorEvery account you connect is there in the same chat.
  • One idea, a post per accountEach version is written for its platform and that account's voice.
  • You approve every postDrafting and publishing are separate steps. Nothing goes out until you say so.

Questions

Claude Duet and social media, answered

What is Claude Duet?
Anthropic's proactive agent, launched on October 21, 2026. It briefs you each morning, keeps watching your connected apps during the day, and prepares next steps for you to approve. It runs on Claude Opus 5.5 in Anthropic's cloud.
Do I set Antwork up inside Duet?
No. Duet carries over the connected apps of your Claude account, so the custom connector you add at claude.ai is the one it uses. The same connection also works in a normal Claude chat.
Who can use Duet?
For now, Claude Pro and Max subscribers in the US who have come off the waitlist. Team and Enterprise plans are not part of the preview. Antwork itself works on every Claude plan, Free included.
Will Duet post anything without asking me?
Drafting never publishes. Antwork's tools save drafts as drafts, scheduling or publishing is a separate step you ask for, and Duet asks for approval before acting for you.
