🔌 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 excel-mcp-server stdio

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

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

uvx excel-mcp-server sse

SSE transport connection:

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

3. Streamable HTTP Transport (Recommended for remote connections)

uvx 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 excel-mcp-server streamable-http
Example (Linux/macOS):
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 for complete documentation of all available tools.
