MCP took its first real public beating the same days four vendors bet roadmaps on it.

A post titled "MCP was always a bad idea?" reached 197 points on Hacker News September 20, and Ruby UTCP ranked on Product Hunt the next day pitching a "secure, scalable alternative to MCP for tool calling" at 95 votes, the argument being that a JSON manual describing a tool's native HTTP/gRPC/CLI endpoint avoids the proxy-server wrapper tax. In the same 48 hours Sabre declared MCP the successor to NDC, Salesforce shipped Headless 360 on MCP, Huawei Cloud opened 5,000 general and 1,000 industry MCP assets, and WSO2 shipped MCP-level governance. Load-bearing for enterprise roadmaps at the exact moment the architecture is being seriously contested. I'd rather have that argument now than in 2028.
