🔍 SEO-Auditor MCP Server (v2.0)

High-performance Model Context Protocol (MCP) Server & CLI for 360° Technical SEO, Headless JavaScript Rendering, DOM Hydration Gap Analysis, Schema.org Validation, AEO, and Semantic Cannibalization Detection.

Built for Claude Desktop, Cursor, and Autonomous AI Coding Agents to execute instant technical and JavaScript SEO audits on modern web applications (Next.js, React, Vue, Shopify) directly from natural language prompts.

⚡ Key Features

• 🌐 Headless JavaScript Rendering (V2): Executes full client-side JavaScript via Playwright Chromium to audit dynamic SPAs and client-rendered apps exactly as Googlebot sees them.

• 🔬 JS SEO Hydration Gap Analyzer (V2): Compares raw static HTML against post-hydration Rendered DOM to pinpoint missing titles, injected canonicals, and client-rendered internal links.

• 📸 Full-Page Visual Screenshot Capture (V2): Captures high-resolution full-page screenshots directly into Claude for visual UI/UX & accessibility analysis.

• ⏱️ Browser Performance & Core Web Vitals: Measures DOMContentLoaded, TTFB, and browser page load time in milliseconds.

• 🎯 360° Technical SEO Audit: Audits titles, meta descriptions, canonical URLs, robots meta tags, OpenGraph & Twitter Cards.

• 🏗️ Content & Heading Hierarchy: Validates H1-H6 semantic nesting, detects missing/multiple H1s, and flags broken hierarchy.

• 🤖 AEO / GEO Readiness Analyzer: Scans robots.txt for AI search crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended) to ensure AI search visibility.

• 📐 JSON-LD Schema Validator: Recursively parses and validates Schema.org entities (Article, Product, Organization, LocalBusiness, FAQPage) and reports missing required properties.

• ⚔️ Semantic Cannibalization Matrix: Detects cross-URL keyword cannibalization where multiple pages compete for identical search intent.

• 🗺️ Recursive XML Sitemap Parser: Crawls sitemap indexes and nested XML sitemaps to perform batch audits.
