Get the list of sheets in an Excel file
AI agents call get_excel_sheets 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 queries metadata about an Excel file (sheet names) without reading cell contents, modifying data, executing code, or triggering external operations. It is a pure read operation with minimal blast radius—the worst-case misuse would be information disclosure about file structure, which has low impact.
From the tool's definition Tool name 'get_excel_sheets' and description 'Get the list of sheets in an Excel file' indicate a retrieval operation with no modification of data.
