Inspect Google Sheets images via XLSX export and detect IMAGE() formulas.
AI agents call inspect_sheet_images to retrieve information from Google Workspace MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and analyzes images and IMAGE() formulas embedded in Google Sheets through XLSX export inspection. It performs data extraction and analysis only, with no side effects. The operation is read-only and non-destructive, making it a straightforward Read category tool with low security risk.
From the tool's definition Tool description states it 'Inspect[s]' and 'detect[s]' images and formulas—querying and analyzing existing data without modification. No create, update, delete, execute, or financial operations mentioned.
