Get Excel file structure including sheet list and column headers in JSON format
AI agents call analyzeExcelStructure 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 only retrieves and analyzes existing data structures (sheets and headers) from an Excel file. It performs no writes, deletions, code execution, or financial operations. The capability is purely informational, making it a Read category tool with low severity since misuse would only expose file structure metadata without enabling further unauthorized actions through this tool alone.
From the tool's definition Tool description states it 'Get Excel file structure' and 'readDataBySheetName' and 'readSheetNames' are listed as sibling read tools on this server. The tool retrieves metadata (sheet list and column headers) without modification or side effects.

{
"version": "1",
"default": "deny",
"tools": {
"analyzeExcelStructure": {}
}
}analyzeExcelStructure is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
