Devtools MCP is listed as active in the registry but did not answer our last check. It exposes 7 tools. Last commit 6 Sep 2026.
Developer toolkit: UUID, timestamp, unit conversion, JSON tools, and QR code (SVG). Free.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 7 September 2026. No other catalogue keeps this.
Over the last week it answered 0.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.
