DestructiveDescription
Lots of what makes a page work lives in custom fields a plugin reads - the SEO title Yoast or Rank Math shows in Google, a product subtitle, a 'featured' flag that controls where something appears. Normally you'd click into each post and hunt through plugin boxes to change them. Instead, just tell Claude or ChatGPT what to set and Easy MCP AI updates that field on the post for you, whether one post or many in a single conversation - no dashboard required.
