Automate your socials with Claude
Claude connects to Antwork as a custom connector: one URL pasted into the Add custom connector dialog, then a browser authorization. The same connector works in Claude Desktop once you are signed in.
https://api.antwork.io/mcpCustom connectors need Claude Pro, Max, Team or Enterprise.
Connect it
- 01Open the connector dialogClaude opens its Add custom connector dialog with the MCP URL already on your clipboard, so there is nothing to retype.
- 02Name it and paste the URLSet the name to antwork, paste the URL into Remote MCP server URL, leave Advanced settings empty, and click Add.
- 03Authorize, then connect the social accountApproving the OAuth screen makes the connection live. Ask Claude to connect your account and it renders a panel with a button per platform.

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- ›The consent screen keeps reappearing — the session expired or the grant was revoked.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.
Your agent already writes. Let it post.
One command, one consent screen, and every connected account is something you can just ask for.
