Excel MCP Server for manipulating Excel files

A Model Context Protocol (MCP) server that lets you manipulate Excel files without needing Microsoft Excel installed. Create, read, and modify Excel workbooks with your AI agent.

Features

• 📊 Excel Operations: Create, read, update workbooks and worksheets
• 📈 Data Manipulation: Formulas, formatting, charts, pivot tables, and Excel tables
• 🔍 Data Validation: Built-in validation for ranges, formulas, and data integrity
• 🎨 Formatting: Font styling, colors, borders, alignment, and conditional formatting
• 📋 Table Operations: Create and manage Excel tables with custom styling
• 📊 Chart Creation: Generate various chart types (line, bar, pie, scatter, etc.)
• 🔄 Pivot Tables: Create dynamic pivot tables for data analysis
• 🔧 Sheet Management: Copy, rename, delete worksheets with ease
• 🔌 Triple transport support: stdio, SSE (deprecated), and streamable HTTP
• 🌐 Remote & Local: Works both locally and as a remote service

Usage

The server supports three transport methods:

1. Stdio Transport (for local use)

uvx mcp-excel-tools stdio

{
   "mcpServers": {
      "excel": {
         "command": "uvx",
         "args": ["mcp-excel-tools", "stdio"]
      }
   }
}

2. SSE Transport (Server-Sent Events - Deprecated)

uvx mcp-excel-tools sse 

SSE transport connection:

{
   "mcpServers": {
      "excel": {
         "url": "http://localhost:8000/sse",
      }
   }
}

3. Streamable HTTP Transport (Recommended for remote connections)

uvx mcp-excel-tools streamable-http

Streamable HTTP transport connection:

{
   "mcpServers": {
      "excel": {
         "url": "http://localhost:8000/mcp",
      }
   }
}

Environment Variables & File Path Handling

SSE and Streamable HTTP Transports

When running the server with the SSE or Streamable HTTP protocols, you must set the EXCEL_FILES_PATH environment variable on the server side. This variable tells the server where to read and write Excel files.

• If not set, it defaults to ./excel_files.

You can also set the FASTMCP_PORT environment variable to control the port the server listens on (default is 8017 if not set).

• Example (Windows PowerShell):

  $env:EXCEL_FILES_PATH="E:\MyExcelFiles"
  $env:FASTMCP_PORT="8007"
  uvx mcp-excel-tools streamable-http
  

• Example (Linux/macOS):

  EXCEL_FILES_PATH=/path/to/excel_files FASTMCP_PORT=8007 uvx mcp-excel-tools streamable-http
  

Stdio Transport

When using the stdio protocol, the file path is provided with each tool call, so you do not need to set EXCEL_FILES_PATH on the server. The server will use the path sent by the client for each operation.

set EXCEL_FILES_PATH can help agent as soon as possible to find the Excel file, actually every tool's env and base path diffent another one, but they should resolve the relative path to absolute path.

Available Tools

The server provides a comprehensive set of Excel manipulation tools. See TOOLS.md for complete documentation of all available tools.
