We aggregate from the official MCP registry + community submissions, then actually connect to every server periodically and report:
* Health – Is the server up right now?
* Auth – how to authenticate to the server?
* Schema – what tools are available?
* Changelog – record of schema changes (new tools added, description updates, etc).
Additionally, if you are using our one-click connector, you can consolidate authentication/logging of all your MCP servers in one place. 100% free – no subscription required.
