List all sheets/tabs in a Google Spreadsheet.
AI agents call gdrive_list_sheets to retrieve information from Mcp Google Gdrive without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and returns information about sheet names and structure within a Google Spreadsheet. It has no side effects, cannot modify data, execute code, or cause financial harm. The blast radius of misuse is minimal — an AI agent could at most enumerate spreadsheet contents, which is a low-risk information disclosure scenario. The operation is purely Read category.
From the tool's definition 'List all sheets/tabs in a Google Spreadsheet' — a read-only query operation that retrieves metadata about existing spreadsheet structure without modifying, executing, or deleting anything.
