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.
Codex
Postdom as a Codex MCP server for social media
Add Postdom as a Codex MCP server and Codex can check your connected accounts, submit finished videos for your approval and read what published on each platform, with Postdom keeping every result.
No card needed. Nothing posts until you approve it.
How to add the Postdom Codex MCP server
Codex registers MCP servers with its own command. Replace the placeholders with your server URL and workspace key from Postdom.
codex mcp add \
--env POSTDOM_API_URL=YOUR_SERVER_URL \
--env POSTDOM_API_KEY=YOUR_WORKSPACE_KEY \
postdom -- npx -y @postdom/mcp@0.4.0Or add it to Codex's config file:
config.toml
[mcp_servers.postdom]
command = "npx"
args = ["-y", "@postdom/mcp@0.4.0"]
[mcp_servers.postdom.env]
POSTDOM_API_KEY = "YOUR_WORKSPACE_KEY"
POSTDOM_API_URL = "YOUR_SERVER_URL"Keep the key out of anything you commit. The package needs Node.js 22 or newer.
Free Codex MCP server
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.
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.
What Codex can do with Postdom
Codex gets 14 tools: workspace status, accounts, the brief, uploads, plans, publishing finished videos, and reading results and performance.
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.
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.
