You write a blog post in the terminal. Claude Blog generates 2,000 words with SEO optimization, images, proper heading hierarchy, and a quality score. Then you spend the next 10 minutes copying the output, pasting it into WordPress, manually uploading images, setting alt text, choosing categories, adding tags, and clicking Publish. That last step is the bottleneck. WP MCP Ultimate eliminates it entirely.
WP MCP Ultimate is a free WordPress plugin that connects any MCP-compatible AI to your WordPress site. Install the plugin, paste one config block into Claude Code, and your terminal can now create posts, upload images, set categories, and publish - all without opening the WordPress dashboard. The complete content pipeline becomes: research, write, optimize, publish. One conversation, zero copy-paste.
What is WP MCP Ultimate?
WP MCP Ultimate is an open-source WordPress plugin that exposes 58 WordPress abilities through the Model Context Protocol (MCP). MCP is a standard that lets AI tools interact with external systems. Instead of manually operating the WordPress dashboard, your AI client sends structured commands through the plugin's REST API.
The plugin works with any MCP-compatible AI client: Claude Code, Cursor, Windsurf, and others. For bloggers using Claude Blog, it means the AI that writes your content can also publish it. One free plugin replaces the entire manual publishing workflow.
The 58 abilities cover posts, pages, media, categories, tags, users, comments, menus, widgets, plugins, themes, settings, and site health. For content creators, the key abilities are:
- Create posts - publish or save as draft with full HTML content
- Upload media from URL - fetch images and upload them with alt text
- Set featured images - attach a media item as the post thumbnail
- Manage categories and tags - create, assign, or update taxonomy terms
- Update existing posts - edit content, change status, modify metadata
- Patch content - update specific fields without rewriting the full post
The Pipeline: Write, Optimize, Publish in One Conversation
Before WP MCP Ultimate, the blogging workflow had a gap. Claude Blog handles the writing. Claude SEO handles the optimization - meta descriptions, keyword targeting, schema markup. But publishing was still manual. Now the full pipeline runs in a single terminal session.
Here is what changes when you add WP MCP Ultimate to the workflow:
| Step | Before (manual) | After (with WP MCP) |
|---|---|---|
| Write content | /blog write in terminal | /blog write in terminal |
| Upload images | Download, open WP Media, drag files, add alt text | AI uploads from URL with alt text automatically |
| Set featured image | Click Set Featured Image in WP editor | AI sets it in the same command |
| Add categories | Check boxes in WP sidebar | AI assigns or creates categories |
| Add tags | Type tags in WP sidebar | AI assigns or creates tags |
| Paste content | Copy HTML, paste into WP block editor | AI creates the post directly |
| Publish | Click Publish button | AI publishes or saves as draft |
| Time spent | 10-15 minutes per post | 0 minutes (automated) |
For a single post, saving 10 minutes is nice. For an agency publishing 20 posts per week, that is over 3 hours saved every week on publishing alone.
Watch It in Action
This demo shows a real blog post being rewritten with Claude Blog and published directly to a live WordPress site, including image uploads and category assignment. The entire workflow happens in one terminal conversation.
Setup in 2 Minutes
Getting WP MCP Ultimate running requires three steps. No build tools, no complex configuration, no server-side changes beyond installing a standard WordPress plugin.
Step 1: Install the plugin
Download WP MCP Ultimate from the GitHub repository or search for it in your WordPress plugin directory. Upload the zip file through Plugins > Add New > Upload Plugin, then activate it.
Step 2: Generate an API key
Go to Settings > WP MCP Ultimate in your WordPress dashboard. Click "Generate API Key." Copy the key. This key authenticates Claude Code (or any MCP client) with your WordPress installation. You can revoke it at any time.
Step 3: Add the MCP config to Claude Code
Open your Claude Code settings and add this to the MCP servers section:
{
"mcpServers": {
"wordpress": {
"url": "https://your-site.com/wp-json/jesuspended/v1/mcp",
"headers": {
"X-API-Key": "your-api-key-here"
}
}
}
}
Replace your-site.com with your WordPress domain and your-api-key-here with the key from step 2. That is the entire setup. For a detailed walkthrough with screenshots, see the setup guide PDF in the GitHub releases.
Content Refresh at Scale
Publishing new posts is only half the story. Most WordPress sites have dozens of old posts that need updating - outdated statistics, stale information, missing images, weak SEO. WP MCP Ultimate makes content refresh a single-conversation workflow.
The process works like this:
- Find the post - ask Claude to list your WordPress posts, filter by category or date range
- Pull the content - Claude reads the existing post content through the plugin
- Rewrite it - use /blog rewrite to optimize the content with current data, better structure, and updated statistics
- Push the update - Claude updates the post in WordPress with the rewritten content, new images, and updated metadata
No exporting, no copying between tabs, no manual image re-uploads. If you have 50 posts that need refreshing, you can work through them one conversation at a time. Each update takes minutes instead of the 20-30 minutes of manual editing per post.
This pairs well with the AI content pipeline approach. Use /blog audit to identify which posts need attention, then refresh them through the MCP connection.
The Full Ecosystem
WP MCP Ultimate is one piece of a larger open-source content toolkit. Each tool handles a different stage of the content lifecycle:
- Claude Blog - writes, scores, and optimizes blog posts (getting started guide)
- Claude SEO - technical SEO audits, schema markup, keyword targeting, site-wide optimization
- WP MCP Ultimate - publishes content directly to WordPress with images, categories, and tags
- Rankenstein - cloud SEO platform for teams
All of these tools are built by Daniel Agrici and the open-source community. Claude Blog and Claude SEO are MIT licensed. WP MCP Ultimate is GPL-2.0 licensed (standard for WordPress plugins). Everything is free.
The tools work independently, but the real power comes from combining them. Write a post with Claude Blog. Run the SEO check with Claude SEO. Publish it to WordPress through WP MCP Ultimate. Score the live page. Fix any issues. All in the terminal, all in one session.
