The social media MCP server for your AI
The Postiz MCP lets ChatGPT, Claude, Cursor, and any AI assistant post to your social media for you. Just connect it once with a single link — then ask in plain English to schedule and publish across 30+ platforms.
Please make sure there is always a human in the loop.
Why use a social media MCP server?
MCP (Model Context Protocol) is the standard way AI assistants plug into the apps you use. Connect Postiz once and your AI becomes a social media agent that manages your whole presence — without you ever opening a dashboard or copy-pasting between tools.
Just ask, in plain English
Tell your AI what you want to post and when. It writes it, schedules it, and publishes it for you — no menus, no forms.
30+ platforms at once
Post to X, LinkedIn, Instagram, TikTok, YouTube, Reddit, and more — all from a single conversation with your AI.
Connect once with a link
No installs or technical setup. Paste one link into ChatGPT, Claude, or Cursor and you're ready to go.
Schedule ahead
Ask your AI to plan a week of content and pick the times. It schedules everything in Postiz so it goes out automatically.
Create images & videos
Your AI can generate images and videos through Postiz and attach them to your posts — all in the same request.
Stays in your account
The connection uses your private Postiz key, so your AI only touches the accounts you've already connected.
Connect it in under a minute
First, grab your personal MCP link, then add it to the AI tool you already use.
In Postiz, go to Settings → Developers → Public API and copy your API key. Your personal link looks like this:
