    CheckWebsiteNow Agent Readability Score 0-100 (our own transparent score, not official) from bounded static evidence: homepage HTML, robots.txt, llms.txt, API/MCP discovery files, sitemap and Markdown negotiation. Every deduction names its fix. MCP discovery is advertised, not t…

  • get_service_info

    Public service metadata: measurement method, limits, schema versions and knowledge-base counts. Never visitor analytics.
