Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

This repository contains Model Context Protocol (MCP) servers for interacting with Microsoft Office applications through AI assistance. Currently supported applications:

  • PowerPoint: Create and manipulate presentations
  • Excel: Interact with workbooks and spreadsheets

Both servers use pywin32 for COM automation, allowing direct interaction with running Office applications.

Prerequisites

  • Windows operating system
  • Microsoft Office installed (PowerPoint and/or Excel)
  • Python 3.7+
  • pywin32 package

Installation

  1. Clone the repository:
git clone https://github.com/jenstangen1/mcp-pptx.git
cd mcp-pptx
  1. Install dependencies using uv:
uv pip install pywin32
  1. Run the pywin32 post-install script with administrator privileges:
python C:\path\to\your\env\Scripts\pywin32_postinstall.py -install

Setting up with Claude

To integrate these MCP servers with Claude, add the following configuration to your Claude Desktop app settings:

{
"mcpServers": {
"powerpoint_mcp_win32": {
"command": "uv",
"args": [
"run",
"mcp_powerpoint_server_win32.py"
],
"cwd": "C:\\path\\to\\your\\workspace"
},
"excel_mcp_win32": {
"command": "uv",
"args": [
"run",
"mcp_excel_server_win32.py"
],
"cwd": "C:\\path\\to\\your\\workspace"
}
}
}

Note: Replace C:\\path\\to\\your\\workspace with your actual workspace path.

PowerPoint MCP Server

The PowerPoint server provides a comprehensive API for AI models to interact with PowerPoint presentations, supporting advanced formatting, financial charts, and data integration.

Questions

What is the Pptx-Xlsx MCP server?

Antrophics Model context protocol to edit powerpoint files

What tools does Pptx-Xlsx expose?

37 in total: 16 read-only, 20 that write, and 1 that can delete or overwrite (delete_slide). Every one is listed on this page with its risk.

Is Pptx-Xlsx safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B. Separately from the audit: 1 of its tools can destroy data, so scope the token you give it to what you actually need.

What credentials does Pptx-Xlsx need?

No credential environment variables were found in its source, so it appears to need none.

How current is this page?

The grade is for one exact copy of the source (b6ac04845c40), read on 2026-10-08. The repository is watched and re-audited when it changes.
