Post to WordPress from Codex

Codex drafts it. You approve it. PostDelegate posts it.WordPress: Posts or pages with categories, tags and a featured image.

How to post to WordPress from Codex

Add PostDelegate to Codex. Add the server to ~/.codex/config.toml as below. Run codex mcp login postdelegate and sign in in your browser.
~/.codex/config.toml
```
[mcp_servers.postdelegate]
url = "https://app.postdelegate.com/mcp-oauth-dynamic"
```
Connect WordPress in PostDelegate. In WordPress open Users, Profile, Application Passwords and create one for a user who is allowed to create posts. Some hosts and security plugins turn application passwords off.
Ask Codex for a draft. Describe the post in plain words. Codex checks your WordPress channel's rules, creates the post and sends back a preview link.

Teach Codex the posting rules

Add PostDelegate’s AGENTS.md to your repository, so Codex knows the MCP tools, the REST API and the safety rules when it works there. Agent files has the steps.

What to ask Codex

Mention any WordPress setting in plain words and Codex fills it in. Codex can also read text files in your project, such as a changelog or a draft in Markdown.

Draft a WordPress post in the News category with the tags launch and product, and the featured image from my media library.
Schedule this as a WordPress page, status Publish, for Monday at 9:00.
Turn content/case-study.md into a WordPress post as a Draft status, with categories loaded from my site.

What Codex can do on your WordPress channel

Check the rules first. Before writing, it reads your WordPress channel's length limit and required settings.
Draft, schedule or post. It creates a draft, a scheduled post or an immediate post, and runs the same checks as the app.
Use your media. It attaches files from your media library or adds one from a public link.
Review and fix. It lists what is scheduled, changes the WordPress settings of a post that has not gone out, and deletes posts you no longer want.

PostDelegate talks to your site through the WordPress REST API with an application password, a built-in WordPress feature. Your login password is never used. The post type, status, categories and tags are loaded from your own site, so you choose from what actually exists there.

WordPress settings Codex can fill in

Setting	Notes
Title	Required, at least 2 characters.
Post type	Required. Choose from the types on your site, such as posts and pages.
Status	Publish (the default), Draft, Pending or Private.
Categories	Optional. Loaded from your site.
Tags	Optional. Loaded from your site.
Main image	Optional featured image. It is uploaded to your media library.

Before you start

The site must be reachable from the internet with the REST API turned on, and the user needs a role that can create posts.
A security plugin or server setting that blocks the REST API or strips the Authorization header makes WordPress reject the login.

The WordPress channel guide has every field, and MCP tools lists exactly what an assistant can and cannot do.

Questions

Will Codex publish to WordPress without asking me?

Not unless you ask it to. Ask for a draft and the post waits on your calendar until you schedule it, and your workspace's approvals apply as usual. Tools that change data are marked as such, so Codex can ask you before it schedules or deletes anything.

Do I need an API key to connect Codex?

No. Codex signs in with your PostDelegate account through your browser. An API key is only for clients that cannot sign in, as described in MCP clients.

Does it cost extra to use Codex with PostDelegate?

No. The MCP server is on every plan, and Codex runs on your own Codex account, so PostDelegate never charges for AI. Every plan starts with a 7-day free trial with no card.

Can Codex attach images or video to a WordPress post?

It can use files already in your media library, or add one from a public link. It cannot fetch files from your computer, so upload those in the app first. See MCP tools.

Does PostDelegate need a plugin on my WordPress site?

Our guide asks for none. The connection uses your site's REST API and a WordPress application password, which is a built-in feature. Some hosts and security plugins turn application passwords or the REST API off, and then the connection fails with a message saying what to allow.

Can I save a scheduled post as a draft in WordPress?

Yes. Status can be Publish, Draft, Pending or Private, and Publish is the default. Choosing Draft sends the post to WordPress as a draft when the scheduled time arrives.
