Half the social posts on the internet get drafted in ChatGPT anyway, then copied into some scheduler tab by hand. The copy-paste step is the silly part, and a custom connector removes it: ChatGPT talks to planpo.st directly and the draft becomes a scheduled post in the same conversation.
It works over MCP, the same protocol Claude and Cursor use, pointed at our hosted endpoint. Nothing to install.
ChatGPT supports remote MCP servers through custom connectors, depending on plan and settings. It connects to hosted servers only, so this is the one client where the local npx option does not apply, and our hosted endpoint is the way in.
I want to post daily about my app launch this week. Draft 5 posts for X and LinkedIn in my usual tone and schedule them 9am each day.
ChatGPT drafts ten pieces of copy, sizes them per network, and calls create_post for each with the right slot. The whole launch week sits in the queue before the conversation ends, and every link in them is tracked.
How did my posts do this month? Revenue, not likes.
The connector pulls get_revenue_overview and answers with attributed amounts per post from your payment provider. The dashboard has the same numbers when you want the full view.
Move everything scheduled for Friday to Monday morning, we slipped the release.
list_posts finds Friday's queue, update_post moves each one, and the agent reads the new schedule back. A minute of chat instead of dragging six posts around a calendar.
Plenty of tools let an agent post. The difference here is what comes back: every link in a scheduled post can be tracked, payments from Stripe, Shopify or RevenueCat are matched to the exact post that caused them, and your agent can read those numbers with the same connection it used to publish. ChatGPT does not just post for you, it finds out whether the post worked.
Connects through custom connectors. Availability depends on your ChatGPT plan and whether developer mode is enabled. Grab an API key from Settings, add the server over the hosted endpoint and the tools appear. The full config, with the sharp edges called out, is on the setup page.
