• TEST_CONNECTION - Test connection to WordPress site

Category and Tag Management

The WordPress MCP Server now supports advanced category and tag management:

Using PREPARE_ARTICLE_METADATA

This tool allows you to:

1. Check if categories and tags exist on your WordPress site
2. Automatically create any categories or tags that don't exist
3. Return the IDs of all categories and tags for use with PUBLISH_ARTICLE

Example workflow:

1. Call PREPARE_ARTICLE_METADATA with category and tag names
2. Get back the corresponding IDs
3. Use those IDs with PUBLISH_ARTICLE to publish your content

Featured Image Support

The WordPress MCP Server now supports adding featured images to articles:

Using PUBLISH_ARTICLE with Images

You can add a featured image to your article in two ways:

1. Via URL: Provide an image_url parameter with a direct link to the image

   "image_url": "https://example.com/path/to/image.jpg"
   

2. Via Base64: Provide an image_base64 parameter with the base64-encoded image data

   "image_base64": "iVBORw0KGgoAAAANSUhEUgAA..."
   

3. Custom Filename: Optionally specify a filename for the uploaded image

   "image_filename": "my-custom-image-name.jpg"
   

The server will:

• Download the image (if URL provided) or decode the base64 data
• Upload the image to WordPress
• Set it as the featured image for the article
• Return the media ID in the response

Using the Standalone API

When using the standalone API, you can provide a featured image either as:

• A file upload using the image form field
• A URL using the image_url form field

Environment Variable Support

All tools now support using environment variables from your .env file as defaults:

• WP_SITE_URL - Your WordPress site URL
• WP_USERNAME - Your WordPress username
• WP_PASSWORD - Your WordPress application password

This means you can call the tools without explicitly providing these parameters if they're set in your environment.
