Get all rows from a sheet
AI agents call get_rows to retrieve information from Google Sheets MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves data from a Google Sheet without creating, modifying, or deleting any content. The operation is non-destructive and non-mutating. While bulk data exposure could carry privacy risks in some contexts, the inherent capability is read-only retrieval. Severity is low because misuse results in unauthorized data access rather than data loss or system compromise.
From the tool's definition Tool name 'get_rows' and description 'Get all rows from a sheet' indicate pure data retrieval with no modification or deletion.
