A tool vanishing is a breaking change for anything that depended on it, and it ships without an announcement. We only know because we read every server's tool list every day and keep the previous one.

How this ranking works
Most catalogues sort by GitHub stars. A star is a bookmark — it costs nothing and never expires. We rank by three things we can verify, and we show the score openly. Every number on this page comes from a check we ran ourselves, and you can see when we ran it.
We send a real MCP handshake to every endpoint every 15 minutes. A server that does not respond cannot be “best” at any install count. Requiring an API key still counts as alive.
Weekly downloads from npm and PyPI, on a logarithmic scale so a single huge package does not flatten the list. Installs mean someone did the work of using it.
Read from the server itself via tools/list, not parsed out of a README. If a
server stops exposing a tool, we record the date it disappeared.
