Automate your socials with ChatGPT
ChatGPT reaches Antwork through a custom app in Developer mode. It is the longest setup of any client here, and the only one where you build the connector yourself rather than pasting a single line.
https://api.antwork.io/mcpCustom connectors are a paid ChatGPT feature, and Developer mode has to be switched on first.
Connect it
- 01Turn on Developer modeSettings, then Apps & Connectors, then Advanced settings. Custom connectors do not appear at all until this is on, which is the usual reason the option seems to be missing.
- 02Create the appBack in Apps & Connectors, click Create app. Name it antwork, paste the MCP server URL, set the connection to OAuth, confirm and create.
- 03Turn on memory, then authorizeSwitch on "Reference memories and chats" so ChatGPT keeps your brand voice across conversations, then sign in to authorize Antwork.

https://api.antwork.io/mcpantworkThe server speaks Streamable HTTP and authenticates with OAuth 2.1, using dynamic client registration and PKCE. ChatGPT 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 ChatGPT:
- ›Antwork's tools do not appear — restart ChatGPT 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- ›The consent screen keeps reappearing — the session expired or the grant was revoked.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.
