BachStudio Excel MCP Server

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.

基于原项目: 本项目 fork 自 haris-musa/excel-mcp-server，由 BachStudio 维护和发布。

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 bachstudio-excel-mcp-server stdio

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

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

uvx bachstudio-excel-mcp-server sse

SSE transport connection:

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

3. Streamable HTTP Transport (Recommended for remote connections)

uvx bachstudio-excel-mcp-server 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 . 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 bachstudio-excel-mcp-server streamable-http

• Example (Linux/macOS):

  EXCEL_FILES_PATH=/path/to/excel_files FASTMCP_PORT=8007 uvx bachstudio-excel-mcp-server 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.

Available Tools

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