View resource metadata complete

1 resource(s) have incomplete metadata

How to fix: Use a ui:// URI and text/html;profile=mcp-app. For mcp-use v1, use widgetMetadata.metadata.widgetDescription; for v2, use the bound tool's view.description. The current description check reads _meta.ui.widgetDescription or _meta["openai/widgetDescription"] on resource contents or linked tools, not resource.description. Consequently, v2 view.description alone may leave this warning: report the checker compatibility gap instead of adding unsupported v1 fields or claiming the warning is fixed.
