Works today: the operating brief
Add Postdom's operating brief to your ChatGPT project instructions. It gives ChatGPT Postdom's rules for planning posts. It connects nothing and calls nothing.

Postdom and the ChatGPT MCP server: what works today
Postdom is not yet a ChatGPT MCP server you can add. ChatGPT can follow Postdom's operating brief today, and live tools run in Claude Code, Codex and Cursor. Postdom itself still makes your posts from your website.
No card needed. Nothing posts until you approve it.
Is Postdom a ChatGPT MCP server today?
Two things are true at once.
Pending verification: live tools
Postdom's hosted endpoint at https://api.postdom.com/mcp is live. Adding it as a ChatGPT connector has not been tested yet, so this page does not claim it works.
Do not paste Postdom's local MCP configuration into ChatGPT. It describes a process for a client to start on your machine, and it would put a workspace key into a conversation.
Free ChatGPT MCP server alternative
Postdom's Free plan costs nothing and needs no card. It makes 1 post a month from your website, posts to 2 accounts on any platform Postdom supports, and keeps the Postdom watermark.
The MCP server, the REST API, the SDKs and webhooks are included on every plan, Free too. Your own agent uses its own model. The 14 tools of @postdom/mcp@0.4.0 run today in Claude Code, Codex and Cursor.
When you want more, Starter is $39 a month for 30 posts, about $1.30 a post. A post is any format and only counts when you approve or schedule it.
Where Postdom's tools run today
Use Postdom as a Claude Code MCP server for live tools.
Or use Postdom as a Codex MCP server.
Or use Postdom as a Cursor MCP server.
Through MCP, Postdom publishes finished videos you supply and reports what happened. It does not make videos over MCP; the posts Postdom writes from your website are made and approved in the app.
A response is not a publication
accepted, requires_approval and scheduled are workflow states. Keep the returned post ID and read it with get_publish until each destination reports published or failed.
An agent cannot approve itself
You own the accounts, the rules and the approval. Your agent prepares the request; you decide what goes out.
A missing metric is not a zero
When a platform does not report a value, Postdom marks it unavailable with the reason, and leaves it out of totals.
What Postdom does for you
Postdom turns your website into ready-to-post videos, slideshows and single images in your brand, and posts the ones you approve to TikTok, Instagram and more.
- 01
Paste your website
Postdom reads your brand from it: logo, colours, fonts, tone, what you do and who it's for.
- 02
Get ready-to-post content
Your For You feed fills with finished posts in formats that already work on TikTok and Instagram: real clips and photos with native text boxes.
- 03
Approve, edit or skip
Nothing posts until you approve it. At your first approval, connect TikTok or Instagram, and Postdom schedules what you approve in your time zone.
- 04
Let it learn
Every approve, edit and skip shapes the next posts. Once 9 of your last 10 posts of one type are approved without edits, Postdom offers to post that type without review.
ChatGPT MCP server questions
Can I add Postdom as a ChatGPT MCP server now?
Not yet. The local package runs in clients that start it on your machine, and the ChatGPT connector path has not been verified.
What does the operating brief give ChatGPT?
Rules, not reach. ChatGPT can plan posts in Postdom's terms and say what a person must approve. It cannot read your workspace or publish.
Which client should I use for live tools?
Claude Code, Codex or Cursor. Each runs all 14 tools of @postdom/mcp@0.4.0.
Do I need an agent to use Postdom?
No. Postdom makes posts from your website and you approve them in the app. MCP is for people who also run their own agent.
