41% of MCP servers fail to respond in new installation study

By PulseAugur Editorial · [1 sources] ·

A study analyzing 12,915 MCP servers found that 41% failed to respond when installed and started in a sandboxed environment. Of the servers that did respond, 59% successfully initialized and listed their tools, with many requiring placeholder API keys to do so. The analysis revealed various reasons for failure, including broken packages, missing dependencies, incorrect SDK versions, and unexpected server behaviors like starting HTTP servers instead of using standard input/output.
