Page Builder Sandwich for AI agents

Set it up in three steps

1. 1

   Check the switch

   You need WordPress 6.9 or later and Page Builder Sandwich 6.24.0 or later. In the plugin’s settings, “Allow AI agents (MCP)” is on unless you turned it off.

2. 2

   Create an application password

   In WordPress, open Users, then Profile, and add an application password named after your AI app. Copy it: WordPress shows it once.

3. 3

   Add the site to your AI app

   Use your WordPress username, the application password and your site’s connection address:

https://example.com/wp-json/pbs/v1/mcp

What an AI agent can do

Everything the plugin’s own screens can do. Actions marked Pro need a Page Builder Sandwich Pro licence.

Free edition

• Self-host a font (Free) — Downloads a Google font family (family, weights, italic) and serves it from this site.
• Add a section to a page (Free) — Adds a ready-made section to a page: at the start, at the end, or after the section at a given position.
• Generate a section with AI (Free) — Turns a one-sentence description into a ready-designed section (real, editable blocks in the site’s brand style) with text written for it. Returns the block markup, and adds it to the start or end of a page when a post_id is given (a revision keeps what was there before).
• Save an SEO title and description (Free) — Saves a meta title and description into the SEO plugin the site uses (Yoast SEO, Rank Math, SEOPress or All in One SEO) and says which ones were written.
• Suggest an SEO title and description with AI (Free) — Reads a page and suggests a meta title (up to 60 characters) and meta description (up to 155), optionally around a focus keyword. Nothing is saved.
• Undo an AI change (Free) — Puts a page back the way it was before an AI change, from the undo_revision that change returned.
• Write image alt text with AI (Free) — Looks at images and saves alt text for them: one image (attachment_id), or every image on a page that has none (post_id). At most 20 images per call; the answer says how many remain.
• Write or rewrite text with AI (Free) — Writes new text, or improves, shortens, expands, changes the tone of or fixes the grammar of a piece of text, with the site’s own AI provider. Returns the new text; nothing on the site is changed.

• Read the site design (Free) — Returns the site-wide colours and fonts (heading and body) every block uses, as the Site design screen shows them.
