Overview

What is openpyxl_mcp_server?

A thin wrapper around the OpenPyXl Python library that exposes its features as a Model Context Protocol (MCP) server, allowing Claude and other MCP clients to fetch data from Excel files.

How to use openpyxl_mcp_server?

Download the executable from GitHub releases, set executable permissions on macOS, then configure your MCP client (e.g., Claude Desktop) to use it as a command-based server. Alternatively, run from source using Python and the OpenPyXl library.

Key features of openpyxl_mcp_server

  • Exposes OpenPyXl features as MCP tools
  • Allows Claude to read Excel file contents
  • Cross-platform (macOS and Windows executables)
  • Supports any MCP client (Cursor, Windsurf, Zed, etc.)
  • Works with local .xlsx files on the user's machine

Use cases of openpyxl_mcp_server

  • Ask Claude to extract specific data or summaries from Excel spreadsheets
  • Automate analysis of financial records stored in .xlsx files
  • Interpret form-like Excel files and guide users on data entry

FAQ from openpyxl_mcp_server

What does openpyxl_mcp_server do that alternatives don't?

It bridges OpenPyXl’s Excel reading capabilities into the MCP protocol, enabling AI assistants like Claude to interact directly with spreadsheet data without manual conversion.

What are the runtime/dependency requirements?

The prebuilt executables have no Python or OpenPyXl dependency. When running from source, you need Python 3, a virtual environment, and the OpenPyXl library installed via pip install -r requirements.txt.

Where does the data live?

All Excel files remain on the user’s local filesystem. The server reads them at the client’s request and does not store or transmit data off‑device.

Are there any known limitations or compatibility issues?

The server only works with MCP clients that support command‑based servers (e.g., Claude Desktop app, Cursor, Windsurf). It does not support the Claude web browser interface. Windows may show security warnings for the downloaded executable.

What transport and authentication does openpyxl_mcp_server use?

It uses the MCP stdio transport (standard input/output). There is no built-in authentication or encryption; security depends on the local client environment.
