Key Advantages

Smart URL Resolution

The find_content_by_url tool can:

• Take any WordPress URL and automatically find the corresponding content
• Detect content types from URL patterns (e.g., /documentation/ → documentation custom post type)
• Optionally update the content in a single operation
• Works with posts, pages, and any custom post types

Universal Content Operations

All content operations use a single content_type parameter:

{
  "content_type": "post",        // for blog posts
  "content_type": "page",        // for static pages  
  "content_type": "product",     // for WooCommerce products
  "content_type": "documentation" // for custom post types
}

Universal Taxonomy Operations

All taxonomy operations use a single taxonomy parameter:

{
  "taxonomy": "category",        // for categories
  "taxonomy": "post_tag",        // for tags
  "taxonomy": "product_category", // for WooCommerce
  "taxonomy": "skill"            // for custom taxonomies
}

Using with npx and .env file

You can run this MCP server directly using npx without installing it globally:

npx -y @instawp/mcp-wp

Make sure you have a .env file in your current directory with the following variables:

WORDPRESS_API_URL=https://your-wordpress-site.com
WORDPRESS_USERNAME=wp_username
WORDPRESS_PASSWORD=wp_app_password

Development

Prerequisites

• Node.js and npm: Ensure you have Node.js (version 18 or higher) and npm installed.
• WordPress Site: You need an active WordPress site with the REST API enabled.
• WordPress API Authentication: Set up authentication for the WordPress REST API. This typically requires an authentication plugin or method (like Application Passwords).
• MCP Client: You need an application that can communicate with the MCP Server. Currently, Claude Desktop is recommended.

Installation and Setup

1. Clone the Repository:

   git clone <repository_url>
   cd wordpress-mcp-server

2. Install Dependencies:

   npm install

3. Create a .env file:

   Create a .env file in the root of your project directory and add your WordPress API credentials:

   WORDPRESS_API_URL=https://your-wordpress-site.com
   WORDPRESS_USERNAME=wp_username
   WORDPRESS_PASSWORD=wp_app_password

   Replace the placeholders with your actual values.

4. Build the Server:

   npm run build

5. Configure Claude Desktop:

   • Open Claude Desktop settings and navigate to the "Developer" tab.
   • Click "Edit Config" to open the claude_desktop_config.json file.
   • Add a new server configuration under the mcpServers section. You will need to provide the absolute path to the build/server.js file and your WordPress environment variables.
   • Save the configuration.

Running the Server

Once you've configured Claude Desktop, the server should start automatically whenever Claude Desktop starts.

You can also run the server directly from the command line for testing:

npm start

or in development mode:

npm run dev

Security

• Never commit your API keys or secrets to version control.
• Use HTTPS for communication between the client and server.
• Validate all inputs received from the client to prevent injection attacks.
• Implement proper error handling and rate limiting.
