Horizon Shield is answering right now. Last checked 11 min ago. It exposes 15 tools.
Buyer-side fair-price checks for Japanese renovation quotes; cost data is on a separate server.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 25 September 2026. No other catalogue keeps this.
A tool that vanishes takes a piece of your agent with it, and the change arrives silently. Watch this server and every such change lands in your inbox.
Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 11 min ago.
