Research direction
Start in GithubClient.java at getLatestAzureMcpRelease around line 103, then trace executeWithRetry at line 64. Inspect the response deserialization involved in the MismatchedInputException and identify the expected result shape; done means the Azure MCP Server initializes without this uncaught exception and the relevant behavior is covered by a test.
