  • 🌐 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

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

uvx excel-mcp-server sse

3. Streamable HTTP Transport (Recommended for remote connections)

uvx excel-mcp-server streamable-http

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 8000 if not set).

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.
