Check whether a site (and, for app builders, the underlying product) is visible and usable to AI agents: LLM crawlers, shopping/browsing agents, and MCP clients.
It is deliberately narrow. AgentRadar does not check general site health, performance, or SEO. Every check answers one question: can an AI agent discover, read, or use this?
npx agentradar scan <url>
# or, with Bun:
bunx agentradar scan <url>
Add --json for machine-readable output:
npx agentradar scan example.com --json
