Is XGuard — Payment Decision & Discovery working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 182 checks got a reply (50.0%), average response time 152 ms. The bar chart above shows every period we have measured.

Did XGuard — Payment Decision & Discovery ever remove tools?

Yes. xguard_resource_details, xguard_discover, xguard_endpoint_details, xguard_status are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.

Does XGuard — Payment Decision & Discovery need an API key?

No. XGuard — Payment Decision & Discovery completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 10 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is XGuard — Payment Decision & Discovery?

It answers our handshake in 152 ms on average, which is faster than 80% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
