Open Graph Preview

Seo REST API MCP

Extract Open Graph and Twitter Card tags from an HTML document (or take them as fields), and return the parsed values, validation issues (missing or too-long title/description/image/url/card), and regenerated <meta> tags. Does not fetch URLs — pass the page HTML.
