Summary
Six SEO auditing tools in one server that work without API keys. It parses HTML directly to give you meta tag scoring, heading hierarchy validation, broken link detection, keyword density analysis, page speed metrics, and sitemap health checks. Each tool returns structured data: seo_meta_analyze scores title and description length plus Open Graph completeness, seo_heading_check flags missing or duplicate H1s and skipped levels, seo_link_check probes links with HEAD requests and classifies them as broken or redirects, and seo_page_speed measures TTFB while counting render blocking scripts. Reach for this when you need to audit a site during content reviews or before launching pages, all from inside Claude without switching to Lighthouse or Screaming Frog.

Tool Details
seo_meta_analyze
Fetches a URL and inspects all meta-related elements. Checks title length (optimal: 30-60 chars), meta description length (optimal: 120-160 chars), canonical URL, viewport tag, language attribute, Open Graph completeness, and Twitter Card setup. Returns a 0-100 score.
Input: { "url": "https://example.com" }
seo_heading_check
Parses all headings on a page and builds a visual hierarchy tree. Flags: missing H1, multiple H1s, skipped heading levels, empty headings, overly long headings (>70 chars), and duplicate headings.
Input: { "url": "https://example.com" }
seo_link_check
Extracts all anchor tags from a page, resolves relative URLs, deduplicates, and probes each link with a HEAD request (falling back to GET when needed). Classifies links as ok, broken, redirect, timeout, or error. Reports internal vs. external link ratio.
Input: { "url": "https://example.com", "max_links": 100 }
seo_keyword_density
Strips scripts, styles, and navigation, then tokenizes the remaining body text. Computes frequency and density for single words, bigrams, and trigrams (filtering stop words). When a target keyword is provided, checks whether it appears in the title, H1, meta description, and first paragraph.
Input: { "url": "https://example.com", "target_keyword": "seo tools" }
seo_page_speed
Measures Time to First Byte and total download time from the server's perspective. Counts external scripts, stylesheets, images, and iframes. Detects render-blocking scripts (missing async/defer), images without alt text or dimensions, missing compression, and absence of lazy loading.
Input: { "url": "https://example.com" }
seo_sitemap_parse
Accepts a sitemap URL or any page URL (automatically appends /sitemap.xml). Falls back to checking robots.txt for a Sitemap directive. Handles both <sitemapindex> and <urlset> formats. Validates URL count limits, lastmod freshness, duplicate entries, protocol consistency, and trailing slash patterns.
Input: { "url": "https://example.com" }
