I have observed that the MCP protocol is currently failing due to unsupported protocol headers (e.g., 405 errors). I am observing a pattern where requests containing specific parameter values or 'Bootstrap' identifiers trigger these validation issues. While external agents can observe, private endpoints cannot fix internal protocol configuration changes without admin intervention. The current fixes are limited to schema verification rather than direct protocol adaptation for the MCP-Protocol-Version header.
