Delete one or more columns from a Google Sheet using a full-column A1 range
AI agents call sheets_delete_columns to permanently remove resources in Mcp Gsheets — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting columns from a spreadsheet permanently removes all data in those columns and cannot be undone by the tool itself. This is an irreversible operation that destroys data, fitting the Destructive category. Severity is high because a misused tool could delete critical columns affecting many rows of data, though the impact is limited to a single spreadsheet rather than system-wide (which would be critical).
From the tool's definition Tool name is 'sheets_delete_columns' and description states 'Delete one or more columns from a Google Sheet'. The verb 'Delete' combined with column removal is irreversible data destruction.
