Research direction
Start in GithubClient.java at getLatestAzureMcpRelease (line 103), then inspect executeWithRetry (line 64) and the Azure MCP initialization path. Reproduce the GitHub release response handling on the listed IntelliJ, Windows, and JDK environment; done means initialization no longer throws MismatchedInputException and the latest release is handled correctly.
