DestructiveDescription
SEO titles, custom scores, promo flags, and any other fields your plugins register with show_in_rest: true can be updated in bulk or individually through Easy MCP AI — just describe the change in your AI client and let Easy MCP AI write it to WordPress. The show_in_rest constraint is intentional: it ensures only fields explicitly exposed via the REST API are writable, keeping metadata changes controlled and auditable.
