Deletes a sheet/tab from an existing Google Spreadsheet. Cannot delete the last sheet.
AI agents call deleteSpreadsheetSheet 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.
The tool permanently removes data (a sheet/tab) from a spreadsheet without the ability to undo the action through normal tool parameters. Deletion of spreadsheet sheets is destructive and irreversible, fitting the Destructive category. Severity is high because it removes user data, though it's constrained by the limitation that the last sheet cannot be deleted, which provides some protection against total data loss.
From the tool's definition Tool name contains 'delete' and description explicitly states 'Deletes a sheet/tab from an existing Google Spreadsheet.' This is an irreversible deletion operation.
