Schedule social media posts from ChatGPT
ChatGPT can write your posts, but it can't put them on Instagram or LinkedIn. Add Fuxux as a custom MCP server and it gets your connected accounts, your drafts and your schedule, and can publish to 12 platforms.

ChatGPT FAQ
Is Fuxux in ChatGPT's plugin directory?
Not yet. Until it is, you add it yourself as a custom MCP server with the steps on this page. It takes about a minute.
Does it work on the Fuxux Free plan?
Signing in works on every Fuxux plan, including Free. Your plan's limits apply as they do in the web app: the Free plan covers 3 connected accounts and 5 published posts a month, and posting to X needs a paid plan.
Which tools does ChatGPT get?
Eight: whoami, list connected accounts, dashboard, and list, get, create, update and delete posts. Creating a post can publish it now, schedule it, or save it as a draft.
Can ChatGPT post without asking me?
It can publish, because publishing is one of the tools. If you want to approve everything first, tell it to "always save posts as drafts", then review and schedule them in your Fuxux calendar.
What happens with TikTok videos?
A TikTok video sent by an assistant arrives in your TikTok inbox, and you finish it in the TikTok app. Other platforms publish directly.
How do I remove ChatGPT's access?
In Fuxux, open Settings and find Connected apps. Removing an app there stops it straight away. An API key is revoked on the API keys page.
Is Fuxux made by OpenAI?
No. Fuxux is an independent social media scheduler and isn't affiliated with OpenAI.
