概要

What is Excel MCP Server?

Excel MCP Server is a Model Context Protocol (MCP) server that reads and writes MS Excel data. It integrates with Excel workbooks in formats such as xlsx, xlsm, xltx, and xltm. It is designed for developers using MCP-compatible clients like Claude Desktop.

How to use Excel MCP Server?

Install via npm (npx @negokaz/excel-mcp-server) or via Smithery. Add the server configuration to your MCP client's mcpServers block, specifying the command as npx (or cmd on Windows) with the appropriate arguments. Use the provided tools (e.g., excel_read_sheet, excel_write_to_sheet) to interact with Excel files by providing file paths and range parameters.

Key features of Excel MCP Server

  • Read and write text values in cells
  • Read and write formulas (strings starting with "=")
  • Create new sheets and copy existing sheets
  • Create tables within a sheet
  • Format cells with borders, fonts, fills, and number formats (Windows only: live editing, screen capture)

よくある質問

Node.js 20.x or later is required to run the server.

3

Can I control how many cells are read per page?

Yes. Set the environment variable `EXCEL_MCP_PAGING_CELLS_LIMIT` to adjust the maximum number of cells read in a single paging operation (default 4000).

Live editing and screen capture tools are only available on Windows. All other tools work cross-platform.
