• REST API Integration: Full access to WordPress REST API endpoints
• Secure Authentication: Uses application passwords for secure API access
• Dynamic Endpoint Discovery: Automatically maps available endpoints for each site
• Flexible Operations: Support for GET, POST, PUT, DELETE, and PATCH methods
• Error Handling: Graceful error handling with meaningful messages
• Simple Configuration: Easy-to-maintain JSON configuration file

Error Handling

The server handles common errors including:

• Invalid configuration file path or format
• Invalid site configurations
• Authentication failures
• Missing or invalid endpoints
• API rate limiting
• Network errors

All errors are returned with descriptive messages to help diagnose issues.

Security Considerations

• Keep your wp-sites.json file secure and never commit it to version control
• Consider using environment variables for sensitive data in production
• Store the config file outside of public directories
• Use HTTPS for all WordPress sites
• Regularly rotate application passwords
• Follow the principle of least privilege when assigning user roles

Dependencies

• @modelcontextprotocol/sdk - MCP protocol implementation
• axios - HTTP client for API requests

Installation

Installing via Smithery

To install WordPress Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install server-wp-mcp --client claude

Manual Installation

npm install server-wp-mcp

Configuration

Getting an Application Password

1. Log in to your WordPress admin dashboard
2. Go to Users → Profile
3. Scroll to the "Application Passwords" section
4. Enter a name for the application (e.g., "MCP Server")
5. Click "Add New Application Password"
6. Copy the generated password (you won't be able to see it again)

Note: Application Passwords require WordPress 5.6 or later and HTTPS.

Configuration File Setup

Create a JSON configuration file (e.g., wp-sites.json) with your WordPress site details:

{
	"myblog": {
		"URL": "https://myblog.com",
		"USER": "yourusername",
		"PASS": "abcd 1234 efgh 5678"
	},
	"testsite": {
		"URL": "https://test.example.com",
		"USER": "anotherusername",
		"PASS": "wxyz 9876 lmno 5432"
	}
}

Each site configuration requires:

• URL: WordPress site URL (must include http:// or https://)
• USER: WordPress username
• PASS: Application password (spaces will be automatically removed)

The configuration key (e.g., "myblog", "testsite") becomes the site alias you'll use when interacting with the server.

Usage with Claude Desktop

Add to your claude_desktop_config.json:

{
	"mcpServers": {
		"wordpress": {
			"command": "node",
			"args": ["path/to/server/dist/index.js"],
			"env": {
				"WP_SITES_PATH": "/absolute/path/to/wp-sites.json"
			}
		}
	}
}

The WP_SITES_PATH environment variable must point to the absolute path of your configuration file.

Example Usage

Once configured, you can ask Claude to perform various WordPress operations:
