plantuml_web

Trust Score
Using nicegui as a PlantUML frontend, you can deploy PlantUML on an intranet.

It's a nicegui demo project with an added MCP (Model Context Protocol) server that exposes PlantUML functionality to AI assistants.

Plantuml jar version: plantuml-1.2025.3.jar

demo

Features

Web Interface

  • Interactive PlantUML editor with live preview
  • Save and load diagrams
  • Responsive UI with resizable panels

MCP Server

  • Generate PlantUML diagrams in SVG or PNG format
  • Validate PlantUML code with detailed error messages

Usage:

With Docker

docker build -t plantuml_web_mcp .

# or pull from dockerhub
# docker pull  2niuhe/plantuml_web_mcp:latest

docker run -d -p 8080:8080 -p 8765:8765 plantuml_web_mcp:latest

Then you can access:

Without Docker

pip install -r requirements.txt
sh start.sh

The start script will launch:

  1. PlantUML server on port 8000
  2. Web interface on port 8080
  3. MCP server on port 8765

Connecting to the MCP Server

You can connect to the MCP server using any MCP client, such as Claude Desktop:

  1. Open Claude Desktop
  2. Go to Settings > MCP Servers
  3. Add a new server with the URL: http://localhost:8765/sse
  4. Restart Claude Desktop

Testing the MCP Server

A test client is provided to verify the MCP server functionality:

python test_plantuml_mcp.py http://localhost:8765/sse

Available MCP Tools

  • generate_plantuml_image: Generate a diagram image from PlantUML code
  • validate_plantuml_syntax: Validate PlantUML code and return validation result
