Is Tailscale MCP by usefulapi working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 159 ms. The bar chart above shows every period we have measured.

No. Tailscale MCP by usefulapi completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 22 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Tailscale MCP by usefulapi?

It answers our handshake in 159 ms on average, which is faster than 81% 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.
