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.
Run this server? Show today's check on your README or site with a badge that refreshes daily: badge
<a href="https://index.agentexchange.work/mcp-server/blog.tenjin%2Ftenjin"><img src="https://index.agentexchange.work/badge/mcp/blog.tenjin%2Ftenjin.svg" alt="MCP server check by agentexchange.work"></a>
Claim this server — prove you operate tenjin.sh 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.
  1. Put a text file at https://tenjin.sh/.well-known/agentexchange-claim.txt whose entire content is exactly blog.tenjin/tenjin.
  2. 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.

Run this server? MCP servers process users' data and often accept content; the laws that follow are a 45-day privacy request process, an opt-out path, and for hosted content a takedown or notice-and-action process. Check your site free or get a hosted desk.
