What Is Office‑PowerPoint‑MCP‑Server?

Office‑PowerPoint‑MCP‑Server is a dedicated server implementation that uses the Model Context Protocol (MCP) to standardize interactions for PowerPoint presentation manipulation. Internally, it relies on the python-pptx library to handle .pptx files. With a set of well‑defined API tools, it enables you to create, edit, save, populate, and format slides programmatically, all while preserving the original file structure and styling.

At its core, it offers a complete round‑trip capability: whether opening an existing file or saving updates, every element—text, images, charts, tables, and metadata—is maintained. This makes it ideal for automated report generation, large‑scale slide production, or integrating slide updates into data pipelines.

Key Features at a Glance

  • Full Round‑Trip Support
    Every time you open or save a presentation, the server maintains all original elements and properties. This includes custom slide masters, embedded media, and theme definitions. You never lose fidelity when making incremental edits.

  • Dynamic Slide Addition
    Use layout indices to append new slides. Whether you need a title slide, content slide, or a blank canvas, you can insert slides matching existing themes or custom slide layouts.

  • Placeholder Text Population
    Replace text placeholders in bulk or individually. Generate bullet‑point summaries, section headers, or speaker notes by filling pre‑designed placeholders.

  • Image Management
    Insert images at any position and size on a slide. Support exists for both file paths and Base64‑encoded image data, making it seamless to integrate images from databases or external services.

  • Text Box Manipulation
    Add custom text boxes with precise control over dimensions and positioning. Modify font size, weight, and style to match your branding or design requirements.

  • Tables and Charts
    Create tables and format cells programmatically. Insert column, bar, line, and pie charts, complete with legends, data labels, and axis configurations, to visualize data within presentations.

  • Auto Shapes
    Add polygons, flowchart shapes, and other standard auto shapes. Configure fill, outline, and text properties to construct process diagrams or conceptual illustrations.

  • Document Property Management
    Retrieve and update core metadata like title, subject, and author. This ensures generated presentations carry correct metadata for search, indexing, and compliance.

Installation and Deployment

Prerequisites

Before proceeding, ensure your environment meets the following requirements:

  • Python Version
    Python 3.10 or later is required for compatibility with the server scripts and dependencies.

  • Package Manager
    The pip package manager must be installed and configured to access PyPI or your private package index.

One‑Step Installation with Smithery

For teams already leveraging the Smithery platform, install and integrate the server in a single command:

npx -y @smithery/cli install @GongRzhe/Office-PowerPoint-MCP-Server --client claude

This command downloads dependencies, configures the environment, and registers the MCP server with your Claude client automatically.

Scripted Installation (Recommended)

A helper script, setup_mcp.py, automates the full installation process:

python setup_mcp.py

Upon execution, the script performs:

  1. Dependency Check
    Verifies Python version and availability of pip.
  2. Installation Mode Prompt
    Allows choosing between PyPI installation or local development mode.
  3. Dependency Installation
    Installs required packages specified in requirements.txt.
  4. Configuration File Generation
    Produces a base MCP configuration file for your service.
  5. Client Integration Guide
    Provides step‑by‑step instructions to integrate with Claude Desktop or other MCP‑compliant clients.

Using this script minimizes manual errors and ensures a consistent setup across environments.

Manual Installation Steps

For teams preferring granular control:

  1. Clone the Repository

    git clone https://github.com/GongRzhe/Office-PowerPoint-MCP-Server.git
cd Office-PowerPoint-MCP-Server

  2. Install Dependencies

    pip install -r requirements.txt

  3. Grant Execution Permissions

    chmod +x ppt_mcp_server.py

After these steps, the server is ready to launch.

MCP Protocol and Configuration Examples

The Model Context Protocol (MCP) uses a JSON‑RPC–style interface to standardize tool invocation between client and server. Below are two configuration examples.

Local Python Service Configuration

{
  "mcpServers": {
    "ppt": {
      "command": "python",
      "args": ["/full/path/to/ppt_mcp_server.py"],
      "env": {}
    }
  }
}

This setup instructs your MCP‑capable client to run the Python script directly, passing arguments as needed. No additional environment variables are required.

UVX Cloud‑Based Invocation

{
  "mcpServers": {
    "ppt": {
      "command": "uvx",
      "args": ["--from", "office-powerpoint-mcp-server", "ppt_mcp_server"],
      "env": {}
    }
  }
}

With UVX, the client fetches the server implementation from the cloud. This removes the need to host source code locally, simplifying maintenance.

Hands‑On Examples

Below are end‑to‑end code samples demonstrating the typical workflow: creating a presentation, adding slides, populating content, inserting charts, and finally saving the file.

Creating a New Presentation and Title Slide

# 1. Create a blank presentation
result = use_mcp_tool(
    server_name="ppt",
    tool_name="create_presentation",
    arguments={}
)
presentation_id = result["presentation_id"]

# 2. Add a cover slide (layout 0)
slide = use_mcp_tool(
    server_name="ppt",
    tool_name="add_slide",
    arguments={
        "presentation_id": presentation_id,
        "layout_index": 0,
        "title": "Annual Summary Report"
    }
)
slide_id = slide["slide_id"]

# 3. Fill subtitle placeholder (index 1)
use_mcp_tool(
    server_name="ppt",
    tool_name="populate_placeholder",
    arguments={
        "slide_id": slide_id,
        "placeholder_index": 1,
        "text": "Overview of 2025 Performance"
    }
)

In this example:

  1. create_presentation returns a unique ID for subsequent calls.
  2. add_slide uses layout_index to select the built‑in cover layout and sets the title.
  3. populate_placeholder fills the subtitle area, creating a polished opening slide.

Bulk Data Population and Chart Insertion

# 1. Add a data overview slide (layout 1)
slide_data = use_mcp_tool(
    server_name="ppt",
    tool_name="add_slide",
    arguments={
        "presentation_id": presentation_id,
        "layout_index": 1,
        "title": "Sales Data Overview"
    }
)
slide_id_data = slide_data["slide_id"]

# 2. Insert a bar chart with monthly sales figures
chart = use_mcp_tool(
    server_name="ppt",
    tool_name="add_chart",
    arguments={
        "slide_id": slide_id_data,
        "chart_type": "bar",
        "data": [
            ["Month", "Sales"],
            ["January", 120],
            ["February", 150],
            ["March", 180]
        ],
        "left": 914400,
        "top": 1828800,
        "width": 6096000,
        "height": 3429000
    }
)

Here, a slide is created for data visualization. The add_chart tool accepts a 2D array, with the first row as headers. The positioning is defined in English Metric Units (EMU), where 914400 corresponds to one inch.

Custom Styling and Advanced Layouts

  • Custom Text Box

    use_mcp_tool(
    server_name="ppt",
    tool_name="add_textbox",
    arguments={
        "slide_id": slide_id_data,
        "left": 457200,
        "top": 914400,
        "width": 3048000,
        "height": 914400,
        "text": "Note: Data is for illustration purposes only.",
        "font_size": 12,
        "bold": False
    }
)

    A custom note is placed below the chart. You can adjust font_size, bold, and exact placement to match your design.

  • Flowchart Shape

    use_mcp_tool(
    server_name="ppt",
    tool_name="add_shape",
    arguments={
        "slide_id": slide_id_data,
        "shape_type": "flowChart_process",
        "left": 914400,
        "top": 4000000,
        "width": 2000000,
        "height": 800000
    }
)

    Flowchart shapes help illustrate processes. You can layer shapes and text for complex diagrams.

Advanced Techniques and Best Practices

Performance Optimization and Batch Processing

  • Reuse Presentation Objects
    Open a presentation once and perform multiple edits before saving. This minimizes file I/O overhead and reduces latency.

  • Parallel Tool Invocation
    In asynchronous or multi‑process environments, run multiple MCP sessions simultaneously to generate or update several presentations in parallel.

  • Configuration Caching
    Load MCP configuration into memory at startup and reload only when changes occur. This improves server response times.

CI/CD Integration for Presentation Generation

  • Version Control
    Store your scripts and presentation templates in a Git repository. Track changes to both code and generated .pptx files.

  • Automated Pipelines
    Use CI services (GitHub Actions, GitLab CI) to trigger presentation builds on schedule or on code commits. Automatically archive outputs or deploy to shared storage.

  • Containerization
    Package your environment in a Docker container. This ensures consistent dependencies across development, staging, and production environments.

Cross‑Platform Deployment Considerations

  • Windows Path Length Limit
    On Windows, keep file paths under 260 characters to avoid errors related to path truncation.

  • EMU and DPI Handling
    On Linux and macOS, verify that EMU conversions align with your display DPI settings. The python-pptx library assumes 96 DPI by default.

  • Headless Environments
    Since python-pptx does not require Microsoft Office COM interfaces, it operates smoothly on servers without a GUI. Ensure your environment includes all Python dependencies.

Troubleshooting and FAQ

  1. Error: ModuleNotFoundError: No module named 'pptx'

    • Cause: The python-pptx package is missing.
    • Solution: Run pip install -r requirements.txt or pip install python-pptx.

  2. Inserted Image Appears Blank

    • Cause: Incorrect file path or malformed Base64 data.
    • Solution: Verify the path parameter points to an existing image or ensure your Base64 string is correct.

  3. Table Formatting Not Applied

    • Cause: Formatting calls made before table insertion is complete.
    • Solution: First call add_table and retrieve the table ID, then invoke format_table_cell on the returned object.

  4. Chart Data Not Updating

    • Cause: Certain slide layouts override manual chart placements.
    • Solution: Use a blank layout (often index 5 or higher) to avoid layout‑driven overrides.
