AgentScore scores websites 0-100 on AI Agent friendliness. Most sites are built for humans, not AI - we analyze DOM semantics, ARIA coverage, selector stability, WebMCP support, and structured data.

Real results: - anthropic.com: 60/100 - github.com: 56/100 (91% CSS-in-JS hash classes) - news.ycombinator.com: 31/100 (table layout, zero semantic tags)
