📊 PPTX MCP Server

A Model Context Protocol (MCP) server that enables AI assistants to create, edit, and manipulate PowerPoint presentations programmatically.

✨ Features

Full PowerPoint Control - Create, read, and modify .pptx files without needing PowerPoint installed
AI-Native Design - Built specifically for LLMs to generate and edit presentations through structured JSON
Rich Formatting Support - Text styling, colors, alignment, bullets, shapes, and backgrounds
Template Workflows - Extract content from existing presentations, modify, and regenerate
Visual Debugging - Generate thumbnail grids to preview slides programmatically
Office XML Access - Direct access to underlying OOXML for advanced customization

🚀 Quick Start

1. Install

# Clone the repository git clone https://github.com/YOUR_USERNAME/pptx-mcp-server.git cd pptx-mcp-server # Install the package pip install -e .

2. Configure Your MCP Client

Add to your MCP settings:

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{ "mcpServers": { "pptx": { "command": "python", "args": ["-m", "pptx_mcp_server"] } } }

Add to your MCP configuration:

{ "mcpServers": { "pptx": { "command": "python", "args": ["-m", "pptx_mcp_server"] } } }

Specify the full path to your Python interpreter:

{ "mcpServers": { "pptx": { "command": "/path/to/your/python", "args": ["-m", "pptx_mcp_server"] } } }

Examples:

Conda: /Users/username/miniconda3/bin/python
venv: /path/to/project/.venv/bin/python

3. Restart Your MCP Client

Restart Claude Desktop, Cursor, or your MCP client to load the server.

textbox - Text content
rectangle - Rectangle (can contain text)
rounded_rectangle - Rounded corners
oval - Circle/ellipse
image - Image file (use path property)
line - Line connector

Supported layouts: 16:9, 4:3, widescreen, standard

Extract Text Inventory

Get all text content from an existing presentation:

{ "pptx_path": "/path/to/presentation.pptx" }

Returns structured JSON:

{ "slide-0": { "shape-0": { "left": 0.5, "top": 1.0, "width": 12.0, "height": 1.5, "paragraphs": [ {"text": "Title Text", "font_size": 44.0, "bold": true} ] } } }

Replace Text Content

Modify text in an existing presentation:

{ "pptx_path": "/path/to/template.pptx", "output_path": "/path/to/output.pptx", "replacements_json": { "slide-0": { "shape-0": [ {"text": "New Title", "font_size": 44, "bold": true} ] } } }

Rearrange Slides

Reorder, duplicate, or remove slides:

{ "template_path": "/path/to/template.pptx", "output_path": "/path/to/output.pptx", "slide_sequence": "0,2,2,1,3" }

0,2,2,1,3 → Keep slide 0, duplicate slide 2, then slides 1 and 3
Omit an index to delete that slide

Unpack/Pack for XML Editing

// Unpack to directory { "office_file": "/path/to/document.pptx", "output_dir": "/path/to/unpacked" } // Pack back to file { "input_dir": "/path/to/unpacked", "output_file": "/path/to/output.pptx" }

🔧 Troubleshooting

Ensure you're using the correct Python environment:

# Check which Python pip uses pip --version # Install with specific Python /path/to/python -m pip install -e .

Verify the config file path is correct for your OS
Ensure JSON syntax is valid (no trailing commas)
Restart the MCP client completely
Check logs for errors

Install LibreOffice and poppler:

# macOS brew install --cask libreoffice && brew install poppler # Linux sudo apt-get install libreoffice poppler-utils

Ensure the output paths are writable and parent directories exist.
