More from our data
Counting one server that is no longer open but keeps an earlier stored list, tools are visible on 106 servers, 1,549 tools in all. Another 575 ask for a sign-in first, so OpenApps records them as auth-gated, never as having zero tools.
When a server's tool list changes, OpenApps records a new version. 7 servers have more than one so far.
