**Note**: The MCP Server manages the creation of the Persistent UI and its authentication using tokens with Persistent UI. You do not need to open the Persistent UI URL in a Web Browser. Please ensure the user running the MCP has access to create and view the Persistent UI for that cluster by following the [EMR Documentation](https://docs.aws.amazon.com/emr/latest/ManagementGuide/app-history-spark-UI.html#app-history-spark-UI-permissions).
