# AgentTrustBot

> Crawler for the agenttru.st directory of AI agents. It discovers hostnames from public Certificate Transparency logs and checks well-known discovery paths (agent cards, MCP server cards) and DNS records (ANS, DNS-AID) for published agents, plus icon fetches and re-checks of listed agents. Formerly AgentTrust-Collector.

## Why it matters to New Runtime (our interpretation)

Means our agent-discovery endpoints were found and evaluated for listing in an AI-agent directory.

Identity: A family name is what a client claims in its user agent. It is verified only when its request came from the operator's published IP ranges or passed forward-confirmed reverse DNS, as reported per family in /crawler-journeys.json. Anyone can claim any name.
