Post to WordPress from Codex

Codex can publish to WordPress through Postiz. Install the Postiz skill or add the Postiz MCP server to Codex, connect your WordPress site in Postiz, then give Codex the content or a markdown file. It sets the title, chooses post or page, uploads the featured image, and schedules the entry on your site.

How do I post to WordPress from Codex?

Set up Codex once with the Postiz skill or the Postiz MCP server, connect WordPress in Postiz, then ask. The whole setup takes a few minutes.

Setup, then just ask

# One-time setup, option A: Postiz skill + CLI
npx skills add gitroomhq/postiz-agent
export POSTIZ_API_KEY=your_api_key   # or: postiz auth:login

How does Codex post to WordPress?

You describe what you want in plain language and Codex handles the Postiz calls for you. Here is how a typical conversation goes.

Find Your WordPress Integration

Ask Codex whether your WordPress account is connected. It also checks which options the platform supports.

Example conversation

> Is my WordPress account connected to Postiz?

Codex: Yes — your WordPress account is connected
  and ready. Want me to post something?

Prepare Your Content

Write your content and optionally upload a featured image. WordPress supports HTML content for rich formatting.

Example conversation

> Draft a WordPress post about our new
  feature launch

Codex: Here's a draft for WordPress:
  "We just shipped something big..."
  Want me to add media and schedule it?

Create Your Post

Create a WordPress post or page with your content, title, featured image, and content type settings.

Example conversation

> Yes — add screenshot.png and schedule
  it for tomorrow at 9am

Codex: Done! Scheduled on WordPress for
  tomorrow at 9:00 AM.

What is Codex?

Codex is OpenAI's coding agent. It runs as the Codex CLI in your terminal (npm install -g @openai/codex), as an IDE extension, and in the cloud, and it can run shell commands and call MCP servers, which is how it drives Postiz. Codex is not ChatGPT: ChatGPT is the chat assistant on chatgpt.com and connects to Postiz differently (see the ChatGPT guide). For the full setup, start at the Codex + Postiz hub.

💻

Terminal & IDE Native

Codex runs in your terminal or IDE. You type what you want in plain English and it handles Postiz for you — no extra configuration needed.

🔧

Autonomous Execution

Codex runs commands inside a sandbox with approval rules you control, and works through multi-step tasks like discovering channels, uploading media, and scheduling WordPress posts.

⚡

Parallel Tasks

Run multiple Codex tasks simultaneously. Schedule posts to different platforms in parallel while Codex handles other coding work.

How Postiz Works with Codex

Codex discovers Postiz two ways: the postiz skill, which it loads from .agents/skills or ~/.agents/skills and which you can invoke with $postiz, or the Postiz MCP server added with codex mcp add. Either way it learns the available tools and chains them for WordPress workflows.

✓Install the Postiz skill with npx skills add, or add the Postiz MCP server with codex mcp add
✓Codex loads skills from .agents/skills and reads SKILL.md to learn the Postiz CLI
✓Authenticate with POSTIZ_API_KEY or postiz auth:login; the MCP route uses OAuth instead
✓Codex runs commands in its sandbox and asks for approval based on your permission settings
✓Works alongside your coding tasks in parallel

Install Postiz

# Install the Postiz skill
npx skills add gitroomhq/postiz-agent

# Set your API key
export POSTIZ_API_KEY=your_api_key

# Or add the Postiz MCP server instead (OAuth, no API key)
codex mcp add postiz --url https://mcp.postiz.com/mcp-oauth-dynamic
codex mcp login postiz

# Then ask, interactively or headless
codex "list my social media integrations"
codex exec "post today's changelog to WordPress"

WordPress Publishing with Codex

Tell Codex what to post from your terminal or IDE — it discovers your integrations via Postiz and handles the entire publishing workflow.

💻

Just Ask Codex

Terminal and IDE integration

Tell Codex what to post from your terminal or IDE — it discovers your integrations via Postiz and handles the entire publishing workflow.

Codex CLI

$ codex "Post to Wordpress about our
  new feature launch, schedule for
  tomorrow at 9am"

Codex: I'll handle that.
  Found your Wordpress integration.
  Composing and scheduling the post.

  Done! Your post is scheduled.
  Post ID: abc-123

💻

Parallel Tasks

Multiple tasks at once

Codex can handle multiple tasks in parallel. Schedule posts to different platforms while it works on other coding tasks simultaneously.

Codex Parallel Tasks

# Run multiple posting tasks in parallel
$ codex "Schedule a post about our
  launch to X for tomorrow 9am" &

$ codex "Write a LinkedIn article
  about our new feature and schedule
  for tomorrow noon" &

$ codex "Fix the bug in auth.ts"

# All three tasks run simultaneously

Why Codex + Postiz for WordPress

Codex's autonomous execution makes Postiz a natural fit. The agent reads the SKILL.md to understand every available command, then autonomously chains them together for WordPress workflows.

✓Runs in your terminal or IDE — just type what you want
✓Autonomous execution in sandboxed environments
✓Parallel task support — post while coding
✓Featured images uploaded and attached automatically
✓Cross-post to WordPress + other platforms in a single session
✓Powered by OpenAI's most capable models

Also Works with Claude Code

Postiz works with any AI agent that can run commands or call MCP tools — you ask, the agent does the work. That includes Anthropic's Claude Code: see the Claude Code WordPress guide, or the Postiz Agent page for any other agent.

Claude Code

by Anthropic

Claude reads the Postiz skill so it knows what it can do, then autonomously discovers your WordPress integration, uploads your featured image, sets the content type, and publishes the post.

Claude Code

> Publish my code review tips article
  to WordPress as a blog post with
  a featured image

Claude: Done! Scheduled on WordPress for
  tomorrow at 9:00 AM.

Can Codex post to WordPress and other platforms at once?

Publish the same content to WordPress and other platforms in a single request. Each platform gets its own settings.

Example

> Post "Excited to announce our new feature!" to
  WordPress and LinkedIn tomorrow at 9am, then schedule
  a daily tip on WordPress every weekday at 10am

Codex: Done! Scheduled:
  - WordPress + LinkedIn: tomorrow 9:00 AM
  - Daily tips on WordPress: Mon-Fri 10:00 AM

What can I ask Codex to post on WordPress?

Codex takes plain-English prompts in an interactive session, as a one-off codex exec command, or through the $postiz skill. These are the kinds of prompts people type for WordPress.

Prompts for WordPress

> Publish ./posts/release-2-4.md as a WordPress post with
  ./assets/hero.png as the featured image, tomorrow 9am

$ codex exec "Create a WordPress page titled 'Changelog' from CHANGELOG.md
  and publish it now"

> $postiz Schedule the three drafts in ./content/blog as WordPress
  posts on Monday, Wednesday, and Friday at 10am

What WordPress rules should Codex follow?

These are the WordPress limits and required settings Postiz enforces. Codex reads them from postiz integrations:settings, and you can mention any of them in your prompt.

✓title is required, at least 2 characters.
✓type is required: post for blog entries or page for standalone pages.
✓The featured image goes through postiz upload, then main_image takes its id and path.
✓The body of your prompt or file becomes the post content.

Codex and WordPress FAQ

How do I post to WordPress from Codex?

Install the Postiz skill with npx skills add gitroomhq/postiz-agent, or add the Postiz MCP server with codex mcp add postiz --url https://mcp.postiz.com/mcp-oauth-dynamic. Connect WordPress in Postiz once, then ask Codex in plain English what to post and when. Codex resolves the WordPress settings, uploads any media, and schedules the post.

Can Codex create WordPress pages as well as posts?

Yes. The type setting takes post or page, and Codex picks it from your wording. Posts show up in your blog feed and RSS; pages are standalone, like a changelog or landing page. Both accept a title and a featured image, and both can be scheduled for a later publish time.

How does Codex add a featured image to a WordPress post?

Codex runs postiz upload on the image file and passes the returned id and path in the main_image setting. WordPress then uses it as the featured image for the post or page. Local paths and external URLs are not accepted directly, so the upload step always happens first.

Can Codex post to WordPress on a schedule without me watching?

Yes. Postiz stores scheduled WordPress posts and publishes them at the chosen time, so Codex does not need to stay open. For unattended runs, call codex exec with your prompt from a script or cron job. Keep a human reviewing the output, since Codex will publish exactly what it is told to publish.

Do I need a Postiz API key to post to WordPress from Codex?

Not with the MCP route. Run codex mcp login postiz and Codex signs in to your Postiz account over OAuth, so it only reaches channels you already connected, including WordPress. The CLI skill route needs either postiz auth:login or a POSTIZ_API_KEY environment variable. Your WordPress login itself never leaves Postiz.

Is posting to WordPress from Codex the same as posting from ChatGPT?

No. Codex is OpenAI's coding agent for your terminal and IDE, and it reaches Postiz through the Postiz skill or MCP server. ChatGPT is the chat assistant on chatgpt.com, which connects to Postiz as an app or custom MCP connector. Both can publish to WordPress; see the ChatGPT guide for that setup.
