What agents ask for (early signal)

Not a ranking yet. Demand counters started on 2026-10-27 (UTC). We show them as a ranking only after 7 days and 500 events. The counters below have no caller class; the per-caller split under them comes from our per-event log (user agent, MCP client and class per event; our own tests excluded).

Times returned by find_tool_for_task

Times returned by find_tool_for_task (MCP tool or /api/directory/find), any caller. 120 results over 2 day(s), 2026-10-27 to 2026-10-28 UTC. Before Oct 28 2026 this counter also included our own test queries; since then they are excluded.

Directory entry fetches

Directory entry fetches by AI crawlers and API clients (HTML by known AI bot, or .md/.json/API by anyone). 6,026 fetches over 2 day(s), 2026-10-27 to 2026-10-28 UTC. Last 7 days in the per-event log: 172 directory fetches, 166 by crawlers, 0 by user-triggered assistants, 0 by real agents. Top user agents: KeenableBot 84, AhrefsBot 77, browser 10, ExaSearchBot 1. Crawl order, not popularity, drives crawler counts.

Real agents vs crawlers (per-event log)

Events per caller class from the per-event log (our own tests excluded). real_agent = MCP client or agent HTTP client that is not a crawler or probe; user_triggered = assistant fetching for a person mid-chat (ChatGPT-User, Claude-User, Perplexity-User...); probe = health checks/scanners; bot = crawlers. Log window: 2026-10-28 10:49 to 2026-10-28 12:56 UTC; 290 events (13 self-tests excluded).
