MCP Compatibility Scan: Only 1 Out of 4356 Passes
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.
