Automate your socials with Claude
Claude connects to Antwork as a custom connector: one URL in the Add custom connector dialog, then a sign-in on Antwork's own consent page. The same connector works in Claude Desktop once you are signed in.
https://api.antwork.io/mcpClaude Pro, Max, Team, or Enterprise required. Custom connectors are not available on the free Claude plan.
Connect it
Every screen is a real recording of claude.ai and Antwork, made on 26 September 2026. The chat list in the sidebar is blurred for privacy; only the cursor, zooms and captions are added.
Click Connect and we'll open Claude's Add custom connector dialog with the MCP URL copied to your clipboard. In claude.ai you can also get there yourself: Customize, then Connectors, then Add, then Add custom connector.

https://api.antwork.io/mcpantworkThe server speaks Streamable HTTP and authenticates with OAuth 2.1, using dynamic client registration and PKCE. Claude handles the token exchange for you — all you see is a browser consent screen.
If it does not work
The three things that go wrong most often when connecting Claude:
- ›Antwork's tools do not appear — restart Claude after installing. Most clients only read their MCP configuration at startup.
- ›The consent screen keeps reappearing — the session expired or the grant was revoked. Approve it once more; grants last 30 days and refresh silently while you keep using them.
- ›The tools answer but report no accounts — the workspace exists, but no social account is connected to it yet. Connect one in the Antwork web app first.
Questions
- Where are connectors in claude.ai now?
- Under Customize, then Connectors. Settings still has a Connectors entry, but it only points you to Customize. Add a custom connector from the Add button there.
- What should I pick for Authentication and OAuth client?
- Keep what Claude detects: Sign in now, and Register automatically. Antwork signs you in with OAuth on its own consent page, so there are no credentials or headers to enter.
- Will Claude post anything without asking me?
- No. Antwork's tools are set to ask for approval, and Claude shows you exactly what it will create before it does, with Allow once, Always allow or Decline. Drafts are saved as drafts; scheduling or publishing is a separate step you ask for.
- Does it work in Claude Desktop too?
- Yes. A connector you add in claude.ai is available in Claude Desktop when you are signed in with the same account.
- Do I need an API key?
- No. You sign in to Antwork and approve the permissions Claude asks for. You can revoke the connection any time from Settings, then Connected apps, in Antwork.
Your agent already writes. Let it post.
One command, one consent screen, and every connected account is something you can just ask for.
