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.

Postdom as a ChatGPT MCP server for social media
Add Postdom as a ChatGPT MCP server and ChatGPT can make slideshows on your brand kit, publish posts to your connected accounts and read each result, with you approving what goes out. It works in Developer mode on ChatGPT Plus, Pro, Business, Enterprise and Education on the web.
Updated
A ChatGPT MCP server is a remote server ChatGPT calls for tools once you add it in Developer mode. Postdom's server at https://api.postdom.com/mcp gives ChatGPT 17 tools to make, publish and track social posts. Postdom is an AI social media tool that turns your website into short videos, slideshows and posts, then publishes them.
Connect the hosted MCP server: 17 tools
Postdom's hosted MCP server at https://api.postdom.com/mcp has all 17 tools, including create_slideshow, which makes a slideshow on your brand kit from slides your agent writes. Nothing to install: clients that support MCP sign-in connect to your workspace, and any client can send a workspace key instead.
Connect ChatGPT in Developer mode:
- In ChatGPT on the web, open Settings, Security and login, and turn on Developer mode (Plus, Pro, Business, Enterprise and Education).
- Open Plugins, choose +, enter Postdom's name and the MCP URL https://api.postdom.com/mcp under Connection, then create the connection.
- Authorize your Postdom workspace. In a new chat, choose Developer mode from the + menu and select Postdom.

How to add the Postdom ChatGPT MCP server
- 01
Turn on Developer mode
In ChatGPT on the web, open Settings, Security and login, and turn on Developer mode. It is on Plus, Pro, Business, Enterprise and Education; a workspace admin may need to allow it.
- 02
Add Postdom
Open Plugins, choose +, enter Postdom's name and the MCP URL https://api.postdom.com/mcp under Connection, then create the connection.
- 03
Authorize and use it
Authorize your Postdom workspace. In a new chat, choose Developer mode from the + menu and select Postdom.
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.
ChatGPT MCP server, free for 7 days
Starter, Growth and Scale start with a 7-day free trial, so you can see posts made from your website before you pay. Cancel anytime. After the trial, Starter is $39 a month for 30 posts.
The MCP server, the REST API, the SDKs and webhooks are included on every plan. Your own agent uses its own model.
ChatGPT MCP
ChatGPT MCP support lets ChatGPT call tools on remote servers you add in Developer mode. With Postdom connected, ChatGPT sees 17 tools: it can check your accounts with list_accounts, make a slideshow with create_slideshow, publish it with publish_video and read the outcome with get_publish. ChatGPT shows each tool call, and Postdom still holds any post the account's review level says a person must approve.
Postdom's operating brief can also go in your ChatGPT project instructions. It gives ChatGPT Postdom's rules for planning posts; the MCP connection is what lets it act on them.
The same server works in Claude Code, Codex and Cursor.
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.
ChatGPT MCP server questions
Can I add Postdom as a ChatGPT MCP server now?
Yes. Turn on Developer mode in ChatGPT on the web (Plus, Pro, Business, Enterprise or Education), add Postdom's MCP URL under Plugins and authorize your workspace.
What does the operating brief give ChatGPT?
It gives rules, not reach. The brief tells ChatGPT how to plan posts in Postdom's terms and what a person must approve; the MCP connection is what lets it read your workspace and publish.
Which other clients work with the same server?
Claude Code, claude.ai, Cursor and Codex connect to the same hosted server and see the same 17 tools.
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.
