MCP servers, tested and ranked.
The MCP ecosystem is growing fast. Most repositories are solo projects with no production testing. We personally install, evaluate, and document the ones that work, with honest pass rates and latency data.
We personally install and test each server with the MCP SDK.40 production tasks completed. No vendor influence.
