Deletes a sheet/tab from an Excel-format file (.xlsx or .xls) on Google Drive. Cannot delete the last sheet.
AI agents call deleteExcelSheet to permanently remove resources in Google Workspace MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes data (a spreadsheet sheet/tab) from a file. Deletion operations are irreversible and cannot be undone, placing this in the Destructive category. The severity is high because an AI agent misusing this tool could destroy important spreadsheet data, though the impact is somewhat limited to a single sheet within a workbook (not the entire file, as the last sheet cannot be deleted).
From the tool's definition Tool name contains "delete" and description explicitly states "Deletes a sheet/tab from an Excel-format file (.xlsx or .xls)" — this is an irreversible deletion operation.
