### Description (declared)

One initialize call to the server endpoint, the way a stock client connects, and a plain verdict: usable, needs a credential (and whether one can be obtained in-band), charged (HTTP 402), unreachable (with the cause), local only, or not listed. Works with an official MCP registry name or a URL; private and cloud-metadata addresses are refused. It also reports which tools were added, removed or changed between monthly snapshots, from a census of every remote listing in the official MCP registry. Free, no key, 30 URL checks a minute per caller.
