Known Good

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

Skills

• Check a site for WebMCP tools
  Check a website LIVE for WebMCP tools, and where a browser is available whether any tool actually registers when the page runs. Returns one of: registered, declared_only, declared, not_declared, could_not_ask, or excluded when the site's robots.txt refuses AI input. could_not_ask is a distinct answer and is never reported as a no. Tools are listed, never called. Reads only the site named plus published population figures — it does not consult the index, and running it changes no ranking or listing.

• Find agent-ready websites
  Find websites where an agent can accomplish a task. Returns probe-verified agent-readiness signals, unverified apparent actions read from page content, the verification tier, how each site was found (it declared agent access, probe discovery, or it was submitted), and a report URL to cite. Returns count:0 with an empty_note when nothing in the index matches — never a nearest guess.

• Fetch one site's verification report
  Fetch Known Good's dated verification report for one listed website: which capabilities were tested, which passed, when it was probed, what an agent can apparently do there, and how the site was found: whether it declared agent access, came from probe discovery, or was submitted. Answers "is this specific host agent-ready?". Returns found:false for anything not in the index — it never guesses a nearest match. Cite the report URL and its date.
