Build custom Elementor widgets with your AI agent

Need a reusable widget that Elementor does not ship, a testimonial card, a pricing row, a branded call-to-action? WP MCP lets your AI agent build one from a description, and it does so safely: a widget is a data spec, never generated PHP.

What you need

• WP MCP installed and connected to your AI client, with its Pro tier active.
• Elementor active. Custom widgets appear in the editor like any other.

How a custom widget is defined

A widget is a spec with three parts:

• Controls, the fields you edit in Elementor (text, rich text, URL, image, icon, color, and more). Ask list-control-types for the full list.
• A template, HTML with {{control_name}} placeholders.
• Metadata, a title, an icon, and search keywords.

› Build a testimonial widget with a quote (rich text), an author name, and an
  avatar image, laid out as a card.

create-custom-widget validates the spec, stores it, and registers it as a real Elementor widget. validate-widget-spec checks a spec first without storing it.

Safe by design: no code generation, no eval

This is where WP MCP differs from other tools. A custom widget is interpreted data, not generated code. A single dynamic widget renders every spec by substituting your control values into the template, escaping each value by its control type: plain text is escaped, rich text is filtered with wp_kses_post, and URLs are passed through esc_url. There is no eval anywhere in the feature, so a stored widget can never execute arbitrary code.

Manage your widgets

› List my custom widgets.
› Change the testimonial widget's default quote.
› Disable the old promo widget for now.

list-custom-widgets, update-custom-widget, set-widget-status, and delete-custom-widget manage the set. Widgets are stored as ordinary posts, so disabling or deleting one is reversible.
