Can ChatGPT schedule and publish social media posts? Connect via MCP

Yes — ChatGPT can schedule and publish social media posts once you connect it to a remote MCP server. ChatGPT's Developer Mode adds custom connectors over HTTPS; point one at SkedCast's MCP endpoint and every read/write tool becomes available in chat, gated by your own confirmation on anything that changes your workspace.

Schedule social media posts with ChatGPT#

  • In ChatGPT, open your profile menu → Settings → Apps & Connectors → Advanced Settings, and toggle Developer Mode on.
  • Go to Settings → Apps & Connectors → Create, and add a custom connector: give it a name, the endpoint URL, and choose OAuth (ChatGPT will run the authorization flow and prompt you to sign in and consent).
  • Start a new chat, click the + in the composer → More → Developer mode, and select your new connector as a source for that conversation.

FAQ

Does ChatGPT support the MCP server without any special setup?
It needs Developer Mode turned on (Settings → Apps & Connectors → Advanced Settings) and a paid plan (Pro, Team, Enterprise, or Edu) — the free tier doesn't support custom remote connectors.
Will ChatGPT publish a post without asking me first?
No — write tools like create_post are flagged non-read-only, so a well-behaved MCP host (including ChatGPT) prompts for confirmation before calling them.
