Model Context Protocol (MCP) server for Microsoft Azure Diagrams

This tool lets you create Microsoft Azure architecture diagrams automatically. You write a short description (using GitHub Copilot in Visual Studio Code to generate it), and the server will turn it into a diagram image. It’s perfect for anyone who wants to quickly draw cloud diagrams without dragging shapes around.

What's included

This MCP server seamlessly creates diagrams using the Python diagrams package DSL. This server allows you to generate Microsoft Azure diagrams, sequence diagrams, flow diagrams, and class diagrams using Python code.

What it does

• Turn a short plain-English sentence into a clean Azure architecture diagram (PNG).
• Uses the Python diagrams package and Azure icons behind the scenes.
• Saves images into the diagrams/ folder in this project.

Features

The Diagrams MCP Server provides the following capabilities:

1. Generate Diagrams: Create Azure diagrams using Python code
2. Multiple Diagram Types: Support for Azure architecture, sequence diagrams, flow charts, class diagrams, and more
3. Customization: Customize diagram appearance, layout, and styling

What you’ll need

1. Visual Studio Code installed → Download here
2. GitHub Copilot → Enable here
3. Python → we’ll install this in the steps below
4. GraphViz (a small program that actually draws the diagrams) → Download here Don’t worry — we’ll go step by step!

Setup Steps or use .devcontainer

1. Install Python

Open a terminal (Command Prompt, PowerShell, or VS Code Terminal) and run:

winget install Python.Python.3.10

⚠️ Make sure the Python installation path is added to your system's environment variables so that python works in the terminal.
Typically, the installer does this automatically, but if not, you can follow this guide.

2. Install GraphViz

Download and install from: https://graphviz.org/download/ On Windows: pick the MSI installer. On Mac: use Homebrew (brew install graphviz).

3. Get the MCP Server

Clone this repository (or download the ZIP and unzip it). Then open it in VS Code.

In the VS Code terminal, run:

pip install -r requirements.txt

4. MCP Configuration

Configure the MCP server in your MCP client configuration (e.g., for Visual Studio Code GitHub Copilot ~/.vscode/mcp.json):

{
  "mcpServers": {
    "Azure Diagram MCP Server": {
      "type": "stdio",
      "command": "python",
      "args": [
        "-m", "azure_diagram_mcp_server.server"
      ],
      "cwd": "PARENT_FOLDER_OF_CLONED_REPO",
    }
  }
}

or docker after a successful docker build -t azure-diagram-mcp-server .:

  {
    "mcpServers": {
      "Azure Diagram MCP Server": {
        "command": "docker",
        "args": [
          "run",
          "--rm",
          "--interactive",
          "--env",
          "azure-diagram-mcp-server:latest"
        ],
        "disabled": false,
        "autoApprove": []
      }
    }
  }

That’s it! 🎉 You now have everything installed.

Using it with GitHub Copilot

1. Open up VS Code GitHub Copilot Agent Mode

2. Type the following into the chat:

   Generate an Azure Architecture Diagram with an Azure Function connected to a SQL Database through a Load Balancer
   

3. GitHub Copilot will want to execute the MCP Function generate_diagram. Please click on Allow to continue.

4. A PNG image will be created in the diagrams folder. Open it and admire your Azure diagram! 🚀

Troubleshooting

• No image appears? Make sure GraphViz is installed (see step 2).
• Copilot doesn’t run? Make sure the GitHub Copilot extension is enabled and that you allowed it to run MCP functions. Check the MCP server too.
• Still stuck? Restart VS Code and try again.
