Excel

This Excel MCP server, developed by Kazuki Negoro, provides a bridge between Model Context Protocol and Microsoft Excel files. It enables reading and writing of spreadsheet data, specifically focusing on text values in xlsx format files. The implementation is designed for Node.js environments and leverages libraries like exceljs for Excel file manipulation. It's particularly useful for scenarios where AI assistants or other MCP-compatible clients need to interact with structured data stored in Excel spreadsheets, such as data analysis, report generation, or automated spreadsheet updates based on AI-driven insights.
