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)
```bash
uvx excel-mcp-server stdio
```
```json
{
"mcpServers": {
"excel": {
"command": "uvx",
"args": ["excel-mcp-server", "stdio"]
}
}
}
```
### 2. SSE Transport (Server-Sent Events - Deprecated)
```bash
uvx excel-mcp-server sse
```
**SSE transport connection**:
```json
{
"mcpServers": {
"excel": {
"url": "http://localhost:8000/sse",
}
}
}
```
### 3. Streamable HTTP Transport (Recommended for remote connections)
```bash
uvx excel-mcp-server streamable-http
```
**Streamable HTTP transport connection**:
```json
{
"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`.
- With these transports, tool `filepath` values must be **relative** to that directory (e.g. `reports/q1.xlsx`); absolute paths and directory traversal are rejected.
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):
```powershell
$env:EXCEL_FILES_PATH="E:\MyExcelFiles"
$env:FASTMCP_PORT="8007"
uvx excel-mcp-server streamable-http
```
- Example (Linux/macOS):
```bash
EXCEL_FILES_PATH=/path/to/excel_files FASTMCP_PORT=8007 uvx 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](TOOLS.md) for complete documentation of all available tools.
