Best practices for authoring a Classic Unbounce landing page from HTML/CSS/JS through Unbounce MCP — create\_page\_from\_html, create\_variant\_from\_html, and update\_variant\_from\_html. Use when the user asks for a Classic or custom-HTML page, when a new page needs something the AI Builder catalog cannot express (a bespoke interactive widget, custom page-level JavaScript), when the account does not have AI Builder, or to edit or add a variant to a page already authored through these HTML tools; also to personalize page text by URL parameter (Dynamic Text Replacement). A new page otherwise goes through the mcp-ai-builder-authoring skill. Not for AI Builder pages or pages hand-built in the Unbounce builder.

## From README

Authoring an Unbounce MCP page These rules apply when you write the HTML/CSS/JS body for createpagefromhtml, createvariantfromhtml, or updatevariantfromhtml. The page is a full-bleed custom-HTML page — you own the markup end to end. Design the page to be optimized for conversions: by default, every layout, copy, and hierarchy decision should serve the page's single conversion goal. This covers MCP-authored pages only, and the split is exclusive both ways: A page hand-built in the Unbounce builder is not editable this way — updatevariantfromhtml refuses it. Replicating or modernizing a builder-built page is a different, audit-first job. An MCP-authored page cannot be edited in the Unbounce builder. Never tell the user they can open, tweak, swap images, or finish the page "in the Unbounce builder/editor" — they cannot. Every edit goes through these MCP tools: the user asks for the change, or supplies updated HTML.
