Research direction

Start with com.microsoft.azure.toolkit.intellij.azuremcp.GithubClient.java at line 103 and inspect the getLatestAzureMcpRelease flow around the reported Jackson exception. Reproduce the Azure MCP Server initialization on IntelliJ 2026.1.4 with plugin 3.97.6-2026.1, then determine why the response has no content; done means initialization no longer raises this exception.
