Get values from a Google Sheet range
AI agents call sheets_get_values to retrieve information from MCP Google Workspace Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves/queries data from Google Sheets without modifying, deleting, or executing operations. It is a straightforward read operation with minimal risk—the only potential concern would be unauthorized access to sensitive sheet data, but that is a permission/auth issue rather than a property of the tool itself. Low severity due to read-only nature and limited blast radius from misuse.
From the tool's definition Tool name 'sheets_get_values' and description 'Get values from a Google Sheet range' indicate data retrieval with no modification.
