WordPress MCP: How Agencies Can Use it to Build AI-First Sites

WordPress has come a long way—from a simple blogging platform to the backbone of over 43% of the web. But in 2025, something even bigger is happening. 

From chatbots and content generation to smart search and contextual personalization, every agency now faces the same question:

How do we integrate AI into our WordPress workflows without reinventing the wheel?

The answer may be simpler—and more powerful—than you think: Model Context Protocol (MCP).

Originally developed to bridge AI models like Claude with real-world tools and systems, WordPress MCP can be your digital agency’s newest hire—an AI-powered assistant that understands your sites, interacts with them, and helps you manage them at scale.

Let’s explore how MCP for WordPress works, what it unlocks, and how you can use it to AI-enhanced WordPress solutions today.

Why Should Agencies Care About WordPress MCP?

If you’re running a WordPress agency or development firm, your revenue model likely depends on time-intensive services: plugin management, theme updates, blog publishing, SEO audits, uptime monitoring, and performance tuning. What if AI could handle half of that?

That’s exactly what MCP for WordPress unlocks.

By deploying a WordPress MCP server, your agency can delegate repetitive tasks to AI models that understand how to fetch blog posts, publish updates, manage comments, and even analyze plugin data—all without needing a human in the loop. 

Many developers are now building AI-powered assistants for their clients using the WordPress MCP protocol. These assistants can fetch analytics, write content drafts, or generate command reports.

What’s more exciting is how scalable this gets. With one WordPress MCP server, you can manage dozens—even hundreds—of sites. 

Let’s say your agency manages 50 client websites. Right now, every plugin update, performance report, or blog revision has to be either manual or semi-automated with custom scripts. But with the WordPress MCP server, you can assign those workflows to Claude or any compatible LLM, which executes them using structured endpoint calls.

It’s not just time-saving—it’s client-satisfying.

The Bigger Picture: From Sites to Services

We’re entering an era where agencies won’t just offer “WordPress development” but will position themselves as AI-enhanced digital partners.

The MCP for WordPress turns static websites into dynamic, interactive platforms where content is intelligent, updates are instant, and insights are just a prompt away. You’ll no longer just build the site—you’ll power how it evolves.

Here are some real-world agency opportunities enabled by WordPress MCP:

• Content Automation: Claude can automatically create new blog drafts or revise existing ones based on tone, SEO rules, or even trending keywords—all through the WordPress MCP server.
  
• Performance Alerts: Use Performance Scanner + AI prompts to notify clients when load speeds dip.
  
• Client Q&A Bots: Hook Claude to the MCP for WordPress to let clients ask questions like, “How many visitors did I get this week?” or “Is my contact form working?”
  

All of this is now possible because WordPress MCP has abstracted the complexity of REST APIs and turned your sites into agent-ready platforms.

How to Set Up the WordPress MCP Server

WordPress agencies and developers can set up a WordPress MCP server in their workflow easily, using this easy-to-understand guide. 

Step 1: Install the WordPress MCP Server

The official WordPress MCP server is open-source and published on npm. You can install it on your local machine, a cloud VM, or even containerize it for broader deployments.

npm install server-wp-mcp

That’s it. You’ve just taken the first step toward AI-first WordPress management.

This package acts as the bridge between your sites and the AI models. It’s the beating heart of every MCP for WordPress setup. And if you’re working across multiple projects, you can run one server to manage them all—centralized, scalable, and elegant.

Step 2: Generate WordPress Application Passwords

Now that the WordPress MCP server is installed, you need a secure way for it to access your WordPress sites. This is where application passwords come in.

Go to your client’s WordPress dashboard and follow these steps:

1. Navigate to Users → Profile
   
2. Scroll to Application Passwords
   
3. Add a label (e.g., “MCP Server Access”)
   
4. Click Add New Application Password
   
5. Copy the generated password securely

Do this for each site you want to connect. This is how the WordPress MCP server will securely authenticate API calls without exposing the main login.

Bonus Tip: Staging environments make this setup even safer. Test your MCP integrations in a disposable WordPress sandbox before going live.

Step 3: Create Your Server Configuration

Now that you’ve installed the WordPress MCP server and created your secure application passwords, it’s time to tell the server which WordPress sites it should connect to. You’ll do this using a simple file called wp-sites.json.

Wondering what it is? It’s just a small text file (in JSON format) that lists the WordPress sites you want to control using AI, along with their login credentials (application passwords, not your main passwords!).

This is how you can create one. 

1. Open a text editor (like Notepad, VS Code, or Sublime). InstaWP comes with a VS Code editor built into the staging sites. 
2. Copy and paste the following structure:
   {

  “client_one”: {

    “URL”: “https://clientone.com”,

    “USER”: “admin”,

    “PASS”: “your-app-password”

  },

  “client_two”: {

    “URL”: “https://clienttwo.com”,

    “USER”: “admin2”,

    “PASS”: “another-password”

  }

}

3. Replace:
   
   • clientone.com and clienttwo.com with your actual site URLs.
     
   • admin and admin2 with the real usernames used for logging into WordPress.
     
   • your-app-password with the application password you generated from Step 2 for each site.
     
4. Save this file with the exact name wp-sites.json.
   

Let’s say you run an agency that manages two sites:

• A blog site for a personal brand
  
• An e-commerce site for a client
  

You could name your entries like this:

{

  “personal_blog”: {

    “URL”: “https://myblog.com”,

    “USER”: “john_doe”,

    “PASS”: “abc123appPassword”

  },

  “client_shop”: {

    “URL”: “https://shopclient.com”,

    “USER”: “admin_shop”,

    “PASS”: “xyz456appPassword”

  }

}

Now, your AI model knows how to reach both.

This configuration file is the central address book for your WordPress MCP server. It tells the server:

• Where your WordPress sites live (their URLs)
  
• How to log in securely
  
• What names to use when sending instructions
  

Whether you’re managing 2, 20, or 200 sites, this approach scales cleanly and securely.

Pro Tip: If you’re testing with InstaWP sandboxes, just use your InstaWP-generated site URL and application password—super quick for rapid prototyping!

Step 4: Launch Your WordPress MCP Server

Okay—you’ve installed the WordPress MCP server and created your wp-sites.json file (which lists the sites your AI will connect to). Now it’s time to actually launch the server so it can start talking to your WordPress sites.

1. Set the environment variable

Copy and paste this into your terminal:

export WP_SITES_PATH=~/path/to/wp-sites.json
It tells the WordPress MCP server where to find your wp-sites.json config file.

Replace this part:
~/path/to/wp-sites.json with the actual location of the file on your computer.

For example, if you saved it on your desktop:

export WP_SITES_PATH=~/Desktop/wp-sites.json

If you’re on Windows using PowerShell, you’ll write it like this:

$env:WP_SITES_PATH = “C:\Users\YourName\Desktop\wp-sites.json”

2. Start the Server

Now run:

npm start

This command actually starts the WordPress MCP server so it can begin listening for instructions from AI agents like Claude.

If everything is working, your terminal will show something like:

WordPress MCP server started with 2 site(s) configured

This means your MCP server has read the config file and is ready to communicate with the WordPress sites listed inside it. Success!

Now that your WordPress MCP server is running, you can test it by connecting Claude (or any compatible LLM). Try prompts like:

“Show me the last 5 posts from client_one”
“Create a new draft post on client_two titled ‘Welcome to AI-Powered WordPress’”
“List all plugins active on client_one”

The AI model sends those commands to your MCP for WordPress setup, and your WordPress MCP server turns them into API calls your site understands.

Pro Tip for Agencies

If you’re using InstaWP to spin up client environments:

• Add each InstaWP site to your wp-sites.json
  
• Start the server once
  
• Instantly gain AI access to dozens of staging or production sites at once
  

This makes managing client sites with MCP for WordPress effortless—and extremely scalable.

Step 5: Test Your WordPress MCP Setup with Claude

Once your WordPress MCP server is running, connect it to Claude or another AI tool that supports JSON tool calling. You can now issue real-time commands like:

• “Fetch all draft posts from client_one”
  
• “Publish a new post titled ‘AI in WordPress 2025’ on client_two”
  
• “Get plugin version list for client_one”
  

These instructions go through the WordPress MCP server, which parses them into authenticated API requests. It’s clean, efficient, and game-changing for agencies.

Build Custom Tools with WordPress MCP

Want even more control? You can extend the WordPress MCP server by building your own custom tools.

This gives your agency the power to productize these AI interactions into services.

Security Best Practices for Live MCP Usage

As powerful as the WordPress MCP server is, it must be handled responsibly—especially in live production environments. Here’s what we recommend:

Best Practice	Why It Matters
Use HTTPS only	Prevent man-in-the-middle attacks
Never commit app passwords to Git	Always keep credentials private
Rotate credentials regularly	Minimize exposure risk
Use scoped WordPress users	Don’t give full admin rights to your AI
Set read-only modes when testing	Avoid accidental site changes
Validate inputs in your tools	Prevent malformed or malicious API calls

And yes, MCP for WordPress has built-in structures to handle these concerns if you configure it thoughtfully.

Using InstaWP staging sites means you can fully test your WordPress MCP server in isolated environments—no risk to production, full visibility into how tools behave.
