Deletes a sheet (tab) from a spreadsheet. Use getSpreadsheetInfo to find the numeric sheet ID.
AI agents call deleteSheet to permanently remove resources in Google Docs, Drive & Sheets 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 from a user's spreadsheet without any reversibility mechanism described. While the blast radius is somewhat contained to a single sheet within a spreadsheet (not an entire file), the irreversible nature of data loss and the potential business impact of losing an entire sheet of data classifies this as Destructive rather than Write.
From the tool's definition The tool 'deleteSheet' performs an irreversible deletion operation on a spreadsheet sheet (tab). The description explicitly states it 'Deletes a sheet' which removes data permanently without the ability to recover the deleted sheet through the tool itself.
