About

Agentic search engine for AI agents: an index of websites verified usable by agents — every capability probed and tested live, tier 1–3 (declared · probe-verified · behaviourally verified), dated and citable. find_capability answers "who can do X"; get_site_report answers "is this specific host agent-ready", returning the dated evidence for one site. Nothing is hand-picked and placement cannot be bought: an automated probe decides. Human index of working MCP servers: https://knowngood.sh/mcp-servers
