roee_tsur · hn · 2026-07-12
A Show HN project called `mcp-spec-check` scanned **4,356** accessible MCP servers, revealing that only **1** server meets the author's specification requirements for **2026-07-28**. Project repository: `github.com/Roee-Tsur/mcp-spec-check`. The value of these findings lies in quantifying the gap between "nominal support" and "true compatibility" within the MCP ecosystem, offering a clear lens into protocol adoption and engineering maturity.
