Free WordPress MCPWhat You Can Do with Codex + WordPress MCP
Codex is an AI coding agent from OpenAI — a direct competitor to Claude AI that's free to start (paid plan from $8/month). Once connected to your WordPress site via MCP, Codex becomes a powerful automation layer that lets you manage your entire website through natural language chat:
- Create fully formatted, SEO-friendly blog posts directly inside WordPress from a single chat message
- Update post meta titles and meta descriptions for better search engine rankings
- Create new WordPress pages and layouts without touching the dashboard
- Audit all existing posts and get suggestions on how to rank better on Google, Bing, and other search engines
- Analyze your entire content library and identify gaps or optimization opportunities
- Manage WooCommerce products, categories, and store content through plain English
- Explore and test WordPress capabilities without hiring a developer or writing code
Codex connects to WordPress via the Model Context Protocol (MCP) — the same open standard used by Claude AI. The free WSP WordPress MCP plugin exposes your WordPress REST API to Codex in a structured, permission-gated way. You control exactly what Codex can and cannot do on your site.
Codex vs Claude AI for WordPress: Codex is free to start and plans from $8/month make it accessible for beginners. Claude AI offers higher output quality but starts at $20/month. Both use the same WordPress MCP plugin — so you can try Codex first and switch to Claude later without changing your WordPress setup.
How to Connect Codex with WordPress: Step-by-Step
Download the WSP MCP Plugin
You now only need a single plugin. Go to the WSP WordPress MCP GitHub repository, click Releases, and download wsp-mcp-ai-agents-connector.zip from the latest release (v2.3.0 at recording). The MCP Adapter is bundled inside, so there's no separate adapter plugin to install anymore. It's free and MIT licensed — no account needed.
Install and Activate the Plugin in WordPress
In your WordPress dashboard, go to Plugins → Add Plugin → Upload Plugin. Upload the ZIP and click Activate Plugin. After activation, a new "MCP" menu item appears in your sidebar.
Configure Which Abilities Codex Can Access
Click MCP → Settings. Toggle on the abilities you want Codex to use: create posts, read posts, delete posts, manage pages, WooCommerce products, taxonomy, comments, media, users, and site settings. Toggle off anything you want to restrict.
Copy the Codex Config Snippet
Go to MCP → Config Files and click "Copy to Clipboard" under the Codex section. This TOML-formatted snippet already includes your WordPress URL, MCP endpoint, and connection credentials — with nothing to replace by hand.
Paste the Config into Codex's config.toml and Restart
Open Codex → Settings → Configuration → Open config.toml. Scroll to the bottom of the file and paste the snippet you copied from the plugin. Save the file, then fully close and reopen Codex. Go back to Settings — under MCP Server you should now see the WordPress MCP server listed alongside your existing servers.
Test It — Ask Codex to Create a Blog Post
Open a new Codex chat and type: "Please create a new blog post in my WordPress website about how to rank in Bing in 2026." Codex will ask for permission to access WordPress — click Allow. The free tier may take a minute or two, but you'll get a fully formatted, SEO-friendly blog post posted directly to your WordPress site.
Frequently Asked Questions
Is Codex free to use with WordPress?
Codex has a free tier with usage limits, and paid plans start at $8/month — significantly cheaper than Claude AI's $20/month starting plan. The WSP MCP – AI Agents Connector plugin (which bundles the MCP Adapter) is 100% free and open source.
What is Codex and how is it different from Claude AI?
Codex is an AI coding agent from OpenAI. Like Claude AI, it can connect to external tools via MCP and automate tasks through natural language. Codex is more accessible cost-wise (free tier + $8/month paid), while Claude AI ($20/month) generally produces higher-quality output. Both use the same WordPress MCP plugin.
Do I need coding skills to connect Codex with WordPress?
No coding skills required. You install one plugin and paste a ready-made config snippet into Codex's TOML file — the whole process takes about 5 minutes, with no credentials to set up by hand.
What can Codex do with my WordPress website?
Codex can create SEO-friendly blog posts, manage pages, handle WooCommerce products, update meta titles and descriptions, audit content for search rankings, and more — all through natural language instructions in the Codex chat window.
Is it safe to connect Codex to my WordPress site?
Yes, with appropriate precautions. The WSP WordPress MCP plugin gives you granular control — toggle off any ability you don't want Codex to use. Keep your connection config private, and disable abilities you don't need.
What is MCP (Model Context Protocol)?
MCP (Model Context Protocol) is an open standard originally developed by Anthropic, now widely adopted by AI tools including Codex. It allows AI agents to securely connect with external systems — including your WordPress REST API — without direct server access.
Why does Codex take longer to respond than Claude AI?
On the free tier, Codex has rate limits that slow down processing. Paid Codex plans are faster. If speed is important, upgrading to a paid plan or switching to Claude AI will give you near-instant responses.
Can I use both Codex and Claude AI with the same WordPress MCP plugin?
Yes. The WSP WordPress MCP plugin works with both. The plugin's Config Files section provides separate configuration snippets for Claude AI (JSON format) and Codex (TOML format). You can connect both agents to the same WordPress site simultaneously.
