SCRIPTMASTERLABS — Provider Trust + CANON is answering right now. Last checked 2 min ago. It exposes 7 tools.
Provider Trust MCP: verify providers before agents trust them + CANON bulk registry lookup (x402).
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 4 September 2026. No other catalogue keeps this.
Everything else answered, so this is steady rather than shaky. We check every 15 minutes, which is how a one-off gets told apart from the start of a pattern, and how you hear about the next one within the hour instead of from your users.
Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 2 min ago.
