Set Theme Compatibility Method is a WordPress ability from Ultimate Addons for Elementor — usable via Easy MCP AI, which connects Claude, ChatGPT, and any AI assistant to your site.
Install Free Plugin →Set Theme Compatibility Method
WriteConfigure the fallback method used for unsupported themes.
Requires the Ultimate Addons for Elementor (Header Footer & Elementor) plugin on WordPress 6.9+ (the WP Abilities API). No ability registers unless the plugin's 'Enable AI Tools' master switch (uae_mcp_settings.enable_abilities) is turned on in settings. Most abilities require the 'manage_options' capability; a smaller set of read/discovery abilities (template and page listing, the Elementor builder read/list/schema abilities, active-template lookup, display-rule locations, and design tokens) instead require only 'edit_posts' or 'read'. Abilities that act on a specific page, post, or template additionally check the current user's per-object 'edit_post' (or 'delete_post') capability on that item. Separately, every non-readonly (Write or Destructive) ability is gated behind a site-wide 'Allow Modifications' setting at registration time: if it is off, none of those abilities are even registered with the WP Abilities API, regardless of capability checks — this covers all template/page CRUD, widget/extension toggles, display-rule updates, theme/settings changes, and the Elementor builder writes alike, not just the builder ones. Eight of those abilities (the seven Elementor page-builder writes — build, insert-widget, update-widget, remove-element, move-element, add-section, add-column — plus pages-create) additionally re-check this same setting explicitly inside execute() as a redundant safeguard.
What it does
This ability changes how the plugin injects header/footer output into themes it does not natively support. It accepts a method of either 'default' or 'css-override', validates it against a whitelist, translates it into the internal stored value, and writes it to the compatibility option. There is no separate write-gate check in this handler beyond the manage_options permission callback. The registration metadata instructs the AI to explain the two available methods and confirm the choice with the user before changing it.
