Update Individual Post is a WordPress ability from Page Builder: Pagelayer – Drag and Drop website builder — usable via Easy MCP AI, which connects Claude, ChatGPT, and any AI assistant to your site.
Install Free Plugin →Update Individual Post
WriteUpdate an existing blog post's title, layout, status, excerpt, categories, tags, or featured image.
Requires the Pagelayer plugin on WordPress 6.9+ (or another source of wp_register_ability()) for the Abilities API — registration is skipped entirely via a function_exists() guard when it isn't available, and ability categories similarly require wp_register_ability_category(). Most abilities require the 'edit_posts' capability; update-global-styles, create-menu, and delete-menu require 'manage_options'. search-images additionally needs a Pexels API key configured on the Pagelayer AI Agents settings page, and get-library-sections/import-library-section call Pagelayer's own hosted library API. Four near-duplicate abilities (get-widget, get-widgets-summary, edit-layout, navigator) are registered in source with mcp_public:false — fully callable over the REST Abilities API but intentionally left out of the advertised MCP tool list as duplicates of get-widget-schema, list-widgets, update-page, and get-page respectively — and are excluded from this listing.
What it does
Updates any of the given fields on an existing post whose post type must be "post"; when pagelayer_data is supplied it replaces the whole layout tree after the inline-CSS gate — no separate content-quality gate is enforced here, unlike create-post/update-page. Categories accept names, created if missing, or numeric IDs, and featured_image accepts either an attachment ID or a URL to sideload.
