Depend on this server? Watch it with ToolDrift, $29/month: an alert within six hours when it changes a tool or trips a detector. Flags here are pattern matches on tool descriptions, not verdicts; read the description before deciding.

Claim this server — prove you operate
topologyindex.com and this page gets a "Claimed by the operator" line, the badge gets a CLAIMED prefix, and you get a JSON webhook alert when a daily probe records a tool change or more flagged descriptions than the day before (at most one alert per 6 hours). No account, no email, nothing to install.

https://topologyindex.com/.well-known/agentexchange-claim.txtwhose entire content is exactlycom.topologyindex/topology-index. - Submit this form. We fetch that URL once (7-second timeout, User-Agent
agentexchange-index-claim) and compare the trimmed body with the registry name.
Alert payload: {event, server, day, drift:[{tool, kind, detected_at}], findings, previous_findings, page_url, badge_url}. Public list of claims (names and hosts only): /v1/claims.json.
