GPT55 Model Gateway is answering right now. Last checked 5 min ago. It exposes 218 tools.
Remote MCP gateway for GPT-5.6 Luna, Soul, Terra, and x402-paid agent tools with no API key.
The linked repository no longer exists on GitHub — it was deleted or made private.
Every tool that appeared, vanished or quietly changed what it asks for. Recorded since 12 August 2026. No other catalogue keeps this.
Over the last week it answered 49.2% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.
