DestructiveDescription
Alt text gaps are one of the most common SEO oversights on WordPress sites — and Easy MCP AI lets your AI client fix them at scale without opening the admin panel. By connecting Claude Desktop, ChatGPT, or any of the 15 supported clients directly to your site, you can audit alt text, rewrite captions, and rename media items across your entire library through a single conversation. Easy MCP AI routes each update through its pure-PHP MCP server, so no Node.js proxy or third-party service sits between your AI and WordPress.
