How agent-ready is your site?

Paste a URL. We'll check 10 things AI agents and AI Overview look for — MCP descriptor, llms.txt, JSON-LD, sitemap, crawler policy — and give you a grade A–F with the exact fix for anything red.

We fetch up to ~800KB of public HTML + the well-known endpoints. Nothing is stored.

What we check

Ten signals, weighted by impact.

  • AHTML manifest at /.well-known/ahtml.json — single trusted entry agents discover first
  • MCP descriptor at /ahtml/mcp.json — lets Claude, ChatGPT et al. connect
  • llms.txt — curated index for LLM crawlers
  • JSON-LD schema — typed entities for SERP and AI Overview
  • Open Graph tags — social previews + many AI crawlers read these
  • Canonical link — concentrates ranking signal
  • Meta description — SERP snippet quality
  • sitemap.xml — fast indexation in Google Search Console
  • robots.txt AI policy — explicit allow for GPTBot, ClaudeBot, PerplexityBot, Google-Extended
  • Page fetch health — 2xx, sane content size, parseable HTML
What this tool is not
  • It is not a full SEO audit — it covers the 10 agent-readiness signals only.
  • It is not a Lighthouse / Core Web Vitals replacement — use PageSpeed Insights for performance.
  • It does not store URLs or results. Each run is stateless.
