Undo Last Builder Change 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 →Undo Last Builder Change
WriteReverts the most recent AI builder change on a post by restoring the automatic pre-change snapshot saved before the last write.
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
Given post_id, the handler reads a post meta snapshot automatically captured before each prior AI builder write; if no snapshot exists it returns a 404 error suggesting Elementor's own revision history instead. If a snapshot is found, it writes the snapshot's data directly back into '_elementor_data', clears the Elementor cache for the post, and then deletes the snapshot meta so it can't be reapplied — supporting only a single level of undo. Its instructions tell the calling AI to confirm the post_id with the user first since this directly overwrites the current layout.

You ask your AI assistant
"Undo the last change the AI made to post 42's layout."
Inputs
| Name | Type | Required | Description |
|---|---|---|---|
| post_id | integer | Yes | The post, page, or HFE template ID to undo the last builder change on. |
Returns
Returns success and a message confirming which post's last change was reverted (or a 404 WP_Error if no undo snapshot is available).
Permission
permission_callback requires current_user_can('edit_posts'); execute() also calls validate_elementor_post() (Elementor-post validation plus current_user_can('edit_post', ID)). It does not call check_modifications_allowed().
