SEO-IntentRank MCP Server (seo-intentrank)

Official Model Context Protocol (MCP) Server for SEO-IntentRank: Human Search Intent Keywords, Technical SEO Audits, Google Lighthouse Core Web Vitals (CLS/LCP/INP), and On-Page Diagnostic Intelligence.

Developed, maintained, and published by AI Build Infra — High-Performance Infrastructure for Artificial Intelligence & Search Engine Optimization.

🌟 Overview

SEO-IntentRank is an enterprise-grade SEO diagnostic MCP Server created by AI Build Infra to equip AI assistants (ChatGPT, Claude Desktop, Google Antigravity, Cursor, and Perplexity) with live web diagnostics.

It bridges the gap between raw technical crawl data and real human search behavior, delivering deep on-page audits, direct Google Lighthouse Core Web Vitals (including exact Cumulative Layout Shift / CLS scores), and semantic Human Search Intent Keyword extraction.

Core Capabilities:

1. 🎯 Human Intent Keyword Engine: Categorizes page search intent into Informational, Commercial Investigation, Transactional, and Navigational; synthesizes high-converting natural human search queries; mines answered questions; and flags AI slop clichés and keyword stuffing.
2. 🔍 On-Page SEO Inspection: Scans <title> (character length & ~580px pixel width estimates), <meta name="description"> (CTA detection), <meta name="robots">, Open Graph tags (og:*), Twitter Cards (twitter:*), and Canonical URL verification.
3. 📐 Media & Image Alt Audit: Detects missing alt attributes, decorative images (alt=""), and missing width/height attributes that cause Cumulative Layout Shift (CLS).
4. ⚡ Lighthouse Core Web Vitals: Fetches exact numeric scores directly from Google Lighthouse / PageSpeed Insights for:
   • Cumulative Layout Shift (CLS) with threshold analysis ($\le 0.1$ Good) and shift element culprit identification.
   • Largest Contentful Paint (LCP), Interaction to Next Paint (INP), First Contentful Paint (FCP), and Time to First Byte (TTFB).
   • Fallback to local DOM-based layout shift heuristics when auditing raw HTML offline.
5. 🏗️ Technical SEO Hierarchy: Checks single <h1> enforcement, non-sequential heading level skips (e.g. H1 → H3), Schema.org JSON-LD structured data validation, robots.txt disallows, sitemap.xml, and text-to-HTML ratios.
