Create beautiful WordPress sites with AI using the new plugin for Claude from Automattic – WP Site Creator

Build WordPress sites with AI through a regular conversation. On February 13, 2026 Automattic released the WP Site Creator plugin for Claude Cowork plus three Skills (Site Specification, Site Design, WordPress Theme Creation). You type the /create-site command, describe your site idea, Claude asks follow-up questions, suggests design variants, and generates a complete block theme deployed locally in WordPress Studio. The Skills work outside the Claude ecosystem too – you can plug them into ChatGPT, Codex, or any other vibe coding tool.

What does this plugin actually do?

You open Claude Cowork, fire up the command and a short description of what you want to build. Claude asks about your industry, tone, business goals, and the sections you need. It shows you three design previews to pick from. You choose a direction, iterate, swap fonts and colors. Within minutes you have a ready block theme with a preview link you can send to a client or your team.

Prompt example

Plaintext
/create-site A website for my fitness coaching business. 
I help busy professionals get strong without living at the gym. 
I want to book discovery calls and share workout tips.
Plaintext

You describe the business, tell it what the site should achieve, and which sections you need. Claude takes that into account, asks about anything missing, and moves on to design proposals.

The project README also mentions two alternative commands: /quick-build runs a fast workflow that generates a block theme with a simple landing page, while /design-site kicks off a more thorough process – first you define the design direction and style tokens, then page layouts, then a full custom theme with content subpages. You pick whichever fits the project’s scale.

The three Skills powering the plugin

The heart of the show is the three Skills – sets of instructions that teach the AI how to handle a specific task. Think of them as the next evolution of prompts. Instead of writing a long instruction every time, you load a Skill and the model knows what to do and how.

  1. Site Specification Skill gathers context about the site. Industry, audience, business goals, must-have features. This is the discovery phase, where the AI asks the right questions before designing anything. View the Skill on GitHub.
  2. Site Design Skill handles the visual layer. It generates design variants, picks fonts, color palettes, and section layouts. This is where you choose the aesthetic direction and iterate until you land on what you actually want. Link to the Skill.
  3. WordPress Theme Creation Skill turns the decisions into working code. It’s built on the Full Site Editing architecture and covers generating templates, template parts, patterns, and functions.php for block themes. Check the instructions.

The Skills are under active development – Automattic updates them weekly. Output quality is climbing day by day, but it’s worth watching the repo, because something that worked last week might have a different structure today.

What is WordPress Studio?

wordpress studio
WordPress Studio – https://developer.wordpress.com/studio/

WordPress Studio is a free, open-source desktop app from Automattic for local WordPress development. It launched publicly in April 2024 and runs on Mac and Windows. It’s powered by WordPress Playground – a project that runs PHP in the browser/app via WebAssembly – and uses a local SQLite database. The result: a new local WordPress site spins up in seconds, no server or database setup needed.

Studio also does a few things that make project work easier. It creates shareable preview links – public URLs to your local site that you can send a client. It syncs both ways with WordPress.com or Pressable (if that’s where you host). It lets you open the site code in any IDE, terminal, or file explorer. And it has a built-in AI assistant that can run WP-CLI commands directly from the interface.

You can download Studio at developer.wordpress.com/studio.

Open source repo: github.com/Automattic/studio.

How to install WP Site Creator

WP Site Creator needs to be installed as a plugin for Claude Code/Cowork – the recommended approach is installing through the Claude plugin marketplace.

Prerequisites:

  1. WordPress Studio installed with CLI enabled
  2. Studio MCP server configured in Claude Desktop (instructions in the studio-mcp/README.md file in the repo, or below)

Installing the Studio MCP server in Claude Desktop

To use this MCP server, you need WordPress Studio CLI available on your machine.

This pre-configuration step won’t be needed once Studio CLI ships as a standalone npm package.

  1. Download and install Studio: https://developer.wordpress.com/studio/
  2. Open Studio
  3. Go to Settings → Preferences (Menu -> Studio -> Preferences)

    wordpress studio preferences
  4. Toggle on: “Enable the studio command in the terminal”

    wordpress studio cli

Verify it works:

Bash
studio --version
Bash

Integration with Claude Desktop

  1. Open the MCP server config:
    • Claude Desktop: Settings → Developer → Edit Config
  2. Add the MCP server entry:
JSON
{
	"mcpServers": {
		"wordpress-studio-mcp-server": {
			"command": "node",
			"args": [ "/ABSOLUTE/PATH/TO/wordpress-agent-skills/studio-mcp/dist/index.js" ]
		}
	}
}
JSON
  1. Quit and reopen the app

Note: In the args field, replace /ABSOLUTE/PATH/TO/ with the absolute path to your cloned wordpress-agent-skills repo. Relative paths won’t work.

Quick install of the WordPress Studio plugin via the Claude marketplace:

Bash
claude plugin marketplace add https://github.com/Automattic/wordpress-agent-skills.git
claude plugin install create-wp-site@wordpress-agent-skills
Bash

Updating, if you already have the plugin:

Bash
claude plugin marketplace update wordpress-agent-skills
claude plugin update create-wp-site@wordpress-agent-skills
Bash

Once installed, you open Claude Code in the WordPress Studio home folder (typically ~/Studio) and run /quick-build or /design-site, depending on how deep you want to go into the design process.

Alternative – manual install: go into the claude-cowork directory of the cloned repo, zip the wp-site-creator folder, and upload the ZIP in the plugins section of your Cowork instance (bottom of the left panel).

Note: The Automattic team says it plainly: “This is early-stage experimentation. The plugins are not polished and the generated themes are not production-ready.” Generated themes aren’t production-ready – treat this as a tool for prototyping and feedback, not a way to ship sites to clients without a quality check.

The Skills also work with ChatGPT and other vibe coding tools

This is where it gets interesting. Skills aren’t locked into the Anthropic ecosystem. You can load them anywhere you work with AI – in ChatGPT, in Codex, in your favorite vibe coding tool. Just tell the model “use this skill” and paste the GitHub link. The rest takes care of itself.
