Description

A single conversation can rebrand your entire WordPress site: tell your AI client the new primary color, heading font, and spacing scale, and Easy MCP AI writes the changes to global styles instantly — no file edits, no Site Editor, no code. Requires an active block theme. Because global styles cascade across every block on the site, this is the highest-leverage design tool Easy MCP AI exposes, and the one most worth pairing with a read-first step.
