The short answer

Can Codex manage your social media?

Yes, through an MCP server.

Codex does not post to social media on its own. Antwork is a Model Context Protocol (MCP) server you add with one command. You connect each account once on that platform's own login screen, and from then on Codex drafts, schedules and publishes to LinkedIn, X (Twitter), Instagram, Threads, TikTok, YouTube, Facebook and Pinterest from where you already work, through each platform's official API.

8 platforms, one connectorEvery account you connect is there in the same chat.
One idea, a post per accountEach version is written for its platform and that account's voice.
You approve every postDrafting and publishing are separate steps. Nothing goes out until you say so.

Pick your platform

What Codex can post to

Each platform has its own rules. The guides cover the setup, what that platform accepts, and what to ask.

Set it up

Connect Codex in 3 steps

A couple of minutes, in Codex.

One command

$ codex mcp add antwork --url https://api.antwork.io/mcp && codex mcp login antwork

1Step 1 of 3
Run the commandIt adds Antwork over HTTP, then runs codex mcp login, which opens an OAuth consent screen in your browser. Approve it; there is no API key to paste into config.toml.
2Step 2 of 3
Connect the social accountStart codex and ask it to connect your account. It returns a connect link per platform; authorize once and Antwork keeps that token alive.
3Step 3 of 3
Draft, then publish as a second stepDrafting and publishing are separate tool calls. Codex writes first and only publishes when you say so, which matters more in a terminal where there is no card to review.

What you can ask

Run every account from one chat

Copy one into Codex to try it. Codex shows you each post before anything is scheduled or published.

Plan

“Plan next week's posts for Instagram, LinkedIn and X, and show me the calendar.”

“Turn this blog post into a post for each of my accounts.”

“Give me three post ideas for this month, based on what has worked.”

Publish

“Post this announcement to all my accounts, each in its own style.”

“Schedule the LinkedIn and X versions for Tuesday at 9am.”

“What is scheduled this week? Move Friday's posts to Monday.”

Learn

“Which account did best last month, and why?”

“Compare my Instagram and LinkedIn engagement this quarter.”

“What should I post more of on each account?”

Questions

Codex and social media, answered

Can Codex post to social media?

Yes, through Antwork. Codex publishes to LinkedIn, X (Twitter), Instagram, Threads, TikTok, YouTube, Facebook and Pinterest from the same place, each account connected once over that platform's own login. Drafting and publishing are separate steps, so nothing goes out until you say so.
