Score: 100/100
Handshake verified by our own probe.
why this score
The latest probe failed: Our safety guard refused the URL (a private address or a redirect off the public internet). The server was up for 80% of its last 30 days, so this counts as a blip and the score holds; it drops once uptime falls below 50%.
pass Answers the MCP handshake 50/50
Handshake verified earlier; the latest probe failed (see the note above).
