Message Box is a WordPress ability from The Plus Addons for Elementor — usable via Easy MCP AI, which connects Claude, ChatGPT, and any AI assistant to your site.
Install Free Plugin →Message Box
WriteAdds the The Plus "Message Box" widget (tp-messagebox) to an Elementor container.
Requires the The Plus Addons for Elementor plugin (which registers under the 'tpae' ability category) on WordPress 6.9+, with Elementor active. Every ability requires the current user to have the 'edit_posts' capability (and 'edit_post' for the specific post being modified); abilities that create or edit content also verify Elementor and, where relevant, the target The Plus widget are available. A subset of abilities (theme templates, template conditions, dynamic tags, popups, and some custom-code abilities) only register when Elementor Pro is active, and many widget abilities load only in the free plugin when the Pro add-on is inactive.
What it does
The execute callback tpae_mcp_add_theplus_messagebox_ability confirms Elementor is active and the tp-messagebox widget is registered, loads the target post's Elementor page data, and builds a settings array from Title, descText (sanitized with wp_kses_post), and dismiss, merged with any raw settings object. It then constructs a new widget element with a generated ID, inserts it into the specified parent container at the given position, and saves the page data. Requires post_id, parent_id, and Title.
