How do I use staruml-controller-dfd-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@staruml-controller-dfd-mcp Add a data store 'Inventory' to the DFD diagram" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

StarUML Controller MCP Server — Data Flow Diagram (DFD)

An MCP (Model Context Protocol) server specialized for Data Flow Diagrams. Enables AI assistants like Claude to programmatically create and manage data flow diagrams — external entities, processes, data stores, and data flows in StarUML.

Architecture

Prerequisites

Node.js 18+
StarUML with the staruml-controller extension installed and running

Setup

1. Clone and build the core package

git clone https://github.com/pontasan/staruml-controller-mcp-core.git
cd staruml-controller-mcp-core
npm install && npm run build
cd ..

2. Clone and build this package

git clone https://github.com/pontasan/staruml-controller-dfd-mcp.git
cd staruml-controller-dfd-mcp
npm install && npm run build

3. Start the StarUML Controller Server

Launch StarUML and open a project (or create a new one)
From the menu bar, select Tools > StarUML Controller > Start Server...
Enter a port (default: 12345) and click OK
The HTTP server starts — all Data Flow Diagram (DFD) tools become available via MCP

4. Configure your AI assistant

Claude Code — add to your project's .mcp.json:

{
  "mcpServers": {
    "staruml-dfd": {
      "command": "node",
      "args": ["/absolute/path/to/staruml-controller-dfd-mcp/dist/index.js"]
    }
  }
}

Or via CLI:

claude mcp add staruml-dfd node /absolute/path/to/staruml-controller-dfd-mcp/dist/index.js

Claude Desktop — add to your config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "staruml-dfd": {
      "command": "node",
      "args": ["/absolute/path/to/staruml-controller-dfd-mcp/dist/index.js"]
    }
  }
}

Restart your AI assistant.
