Create PowerPoint Presentation with ERD from Text Prompt

This project uses LangChain's MultiServerMCPClient to connect to a custom MCP server (Microsoft Office/Visio MCP) and generate a PowerPoint presentation containing an ERD (Entity-Relationship Diagram) visualization.

Prerequisites

• Python 3.8+
• Microsoft Office (PowerPoint/Visio) installed
• MCP Server running with Visio/PowerPoint tools

Installation

1. Clone the repository:

   git clone <repository-url>
   cd microsoft-office-mcp
   

2. Install dependencies:

   pip install -r requirements.txt
   

Usage

Start MCP Server

Run the MCP server that exposes Visio/PowerPoint tools:

python server.py

Run the Agent

Execute the agent script with a prompt describing the desired ERD:

python agent.py

Modify the main() function in agent.py to customize the prompt:

async def main():
    agent = ERDAgent()
    prompt = """
    Create a PowerPoint presentation with an ERD diagram for this scenario:
    
    [Your ERD description here]
    
    Key requirements:
    - Use Crow's Foot notation for relationships
    - Keep entities within slide boundaries
    - Save as vsdx file
    """
    await agent.run(prompt)

How It Works

1. server.py: Implements a FastMCP server that exposes:

   • init_new_visio_document: Creates a new Visio/PowerPoint document
   • draw_erd_entity: Draws ERD entity shapes with specified coordinates
   • connect_entities: Creates relationship connectors between entities
   • save_as_vsdx: Saves the diagram as a .vsdx file

2. agent.py: A LangGraph agent that:

   • Connects to the MCP server using MultiServerMCPClient
   • Uses create_react_agent with Ollama (or another LLM) for reasoning
   • Executes the MCP tools sequentially to build the diagram
   • Streams the agent's thought process to the console

Customization

• LLM Model: Change OLLAMA_MODEL in .env or config.py
• MCP Server URL: Update MCP_SERVER_URL in .env
• Diagram Design: Modify the prompt in agent.py to change:
  • Entities and attributes
  • Relationships and cardinality
  • Document layout and styling

Example Prompt

"""
Design a simple ERD diagram for a gym membership system.

Entities:
- MEMBERS (member_id, name, email, phone, address)
- CLASSES (class_id, name, capacity, instructor)
- MEMBERSHIPS (membership_id, type, start_date, end_date)

Relationships:
- A MEMBER can have one MEMBERSHIP (1:1)
- A MEMBER can attend multiple CLASSES (M:N)
- A CLASS has one instructor (1:1)

Requirements:
- Use Crow's Foot notation
- Keep the diagram clean and organized
- Save as vsdx file with appropriate filename
