Returns a visual tabular map of borders for a range.
AI agents call sheets_get_border_map to retrieve information from Mcp Gsheets without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and displays border formatting information from a spreadsheet range. This is a read-only query operation with no data modification, deletion, or execution of arbitrary logic. The blast radius of misuse is minimal—an agent could only view formatting metadata that is already accessible.
From the tool's definition Tool name and description indicate it 'Returns a visual tabular map of borders for a range' — a retrieval operation that reads formatting properties without modifying data or triggering side effects.
