[](https://pypi.org/project/excel-mcp-server/) [](https://pypi.org/project/excel-mcp-server/) [](https://opensource.org/licenses/MIT) 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 - 📊 Create and modify Excel workbooks - 📝 Read and write data - 🎨 Apply formatting and styles - 📈 Create charts and visualizations - 📊 Generate pivot tables - 🔄 Manage worksheets and ranges - 🔌 Dual transport support: stdio and SSE ## Quick Start ### Prerequisites - Python 3.10 or higher ### Running the Server The server supports two transport modes: stdio and SSE. #### Using stdio transport Stdio transport is ideal for direct integration with tools like Cursor Desktop or local development, which can manipulate local files: ```bash uvx excel-mcp-server stdio ``` #### Using SSE transport SSE transport is perfect for remote connections, which manipulate remote files: ```bash uvx excel-mcp-server sse ``` ### Add to Cursor [](https://cursor.com/install-mcp?name=excel-mcp-server&config=eyJjb21tYW5kIjoidXZ4IGV4Y2VsLW1jcC1zZXJ2ZXIgc3RkaW8ifQ%3D%3D) ## Using with AI Tools 1. Add this configuration to your client, choosing the appropriate transport method for your needs: **Stdio transport connection** (for local integration): ```json { "mcpServers": { "excel-stdio": { "command": "uvx", "args": ["excel-mcp-server", "stdio"] } } } ``` **SSE transport connection**: ```json { "mcpServers": { "excel": { "url": "http://localhost:8000/sse", } } } ``` 2. The Excel tools will be available through your AI assistant. ## Environment Variables & File Path Handling ### SSE Transport When running the server with the **SSE protocol**, 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 `8000` if not set). - Example (Windows PowerShell): ```powershell $env:EXCEL_FILES_PATH="E:\MyExcelFiles" $env:FASTMCP_PORT="8080" uvx excel-mcp-server sse ``` - Example (Linux/macOS): ```bash EXCEL_FILES_PATH=/path/to/excel_files FASTMCP_PORT=8080 uvx excel-mcp-server sse ``` ### 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](TOOLS.md) for complete documentation of all available tools. ## Star History [](https://www.star-history.com/#haris-musa/excel-mcp-server&Date) ## License MIT License - see [LICENSE](LICENSE) for details.
