AI agents call get_range_values to retrieve information from Excel 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 cell values from a specified range in Excel without creating, modifying, or deleting any data. It is a read-only query operation with no side effects, consistent with other Read category tools like 'get_cell_value' and 'get_workbook_info' on the same server. The blast radius is minimal—the agent can only access existing data it is permitted to read.
From the tool's definition Tool name 'get_range_values' and description indicating data retrieval ('取得します' = 'retrieve/get' in Japanese) with no modification capability.
