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.
