This error seems that there was an error between Copilot and GitHub (GH). My add-in never returns an error or requests the Copilot-Vision-Request header. This error maybe relates to Copilot Vision feature, so I cannot help you.

Agreed. It seems more a problem with GitHub and the LLM. I tried several LLMs and one did not throw this exception.

Hi Takeshi, I tested v2.3.11. The mcp identifies the linked diagrams now. Many thanks.

But Copilot throws an issue:
' Sorry, your request failed. Please try again.
Copilot Request id: 37d72ba4-1757-43e8-becc-6763ef90ff8d
GH Request Id: 647D:3E781C:528352:5B6037:696F8921
Reason: Request Failed: 400 {"error" : {"message": "missing required Copilot-Vision-Request header for Vision requests","code" :""}} '

With the older version I also got this issue, but it was gone later. Any ideas?

Many thanks, Paolo.

There should be at least a possibility to retrieve this information, regardless of the theory behind it.

Would a user care, if it is an owned or other referenced diagram? I think, only one or the other can be added to an element. And both are diagrams.

Or just adding composite to get_element_information?

Yes, you are right. We we are "just" using Composite Diagrams only, not Composite Structure Diagrams.

But even my agent is confused about this distinction. Copilot using your mcp says, that "Elements with Composite Diagrams: 0". It does not say "Elements with Composite Structure Diagrams: 0".

Can your mcp be extended to also return Composite Diagrams? This feature is part of Enterprise Architect, that's why it should be also supported by your mcp. Our child diagrams cannot be moved into the structure of the parent diagram, because many parent diagrams are using these Composite Diagrams. Otherwise, this restriction would dominate our complete repository and we could not order it accoring our standards.

Regard to the following Viking comment, now the latest MCP server can generate better BPMN diagrams including Pools, Lanes, better layout, etc.

Just great !

It looks to me like this AI agent does only does the stuff I can easily do myself.

All this can be achieved by just using natural language. Even my grandfather would be able to create a BPMN diagram now.

To make it actually work in a serious modelling environment, it should need to learn and follow the guidelines of the organisation.

You can teach your agent (easily) and the results will quickly improve.

I don't want to rain on your parade, and I'm sure it's really technically a very advanced tool.
But for now I'm not yet able to recommend usage of such a tool to my clients.

I would, I do, we do.

Hi Takeshi, the command seems to have a bug. 'get_element_information' always returns 'empty' for 'Owned Diagrams'. Goal is to find out the composite diagram / child diagram of elements.

Yes, new elements will no longer be placed on diagrams for various reasons, mainly due to user requests and ideas on how to use this MCP, as well as to improve performance.

We can now place multiple elements at once using the place_element_on_diagram tool. I will update the add-in so that it can create two or more elements at once, saving on AI costs and improving performance.

Sorry, I don't understand. I can create new elements, but cannot create a diagram using them? Or do you mean that I have to tell the agent in addition, that I want to place the new elements on a diagrams?

The version 2.2.0 has been released. I found and fixed some issues during my tests, but there may still be others.

I tested the newest version for my UML Class Diagrams. It now creating elements, connectors, attributes, and cardinalities. Awesome

For any reason it does not create the model anymore (empty "diagram" also cretaed, opened, and selected). So, I have to move the elements from the project brwoser to the diagram.

The implementation for adding/modifying attributes and operations (including parameters) has been completed...
I think I can release the new installer today or tomorrow.

Great news

I will consider offering these functions, but not in the near future.

On top of my wish list are attributes for UML classes. Would this be possible in the near future?

Hi Takeshi,

"I haven't tested your workaround solution for BPMN yet, but I will definitely do so.". Here are finally my test results:

• The sterotypes are used and displayed for all elements I was using: events (!), activities, gateways.
  
• As part of the prompt I said which task types to use, but I got only 'abstractTasks'. I will futher investigate this issue.
  
• mcp created lanes for each involved role. But it arranged them as a row (not on top of each other), And it did not put the respective activities into the lanes. Instead Copilot says: "The fundamental issue: The MCP server's createelement and setelementproperty commands don't seem to support proper BPMN lane Containment. This is similar to the limitation we found with UML attributes - the MCP Server (v2.1.0.0) doesn't expose all the necessary commands for complete BPMN diagram modeling."
  
• The layout is quite good. But it is vertical and cannot be changed. BPMN diagrams are more horizonal and this should be the outcome, if the layout cannot be adapted.
  
• The created diagram is not correct but my understanding is that mcp cannot help here (e.g., only diverging gateways have been created, but not converging ones).

Hi Takeshi, Many thanks.

• I will try 2.1.0.
  
• Do you mind to also add the capability to add attributes? For me this is one of the most important feature of an UML class diagram (so so much for other diagrams), because I more use it do describe concepts precisely.
  
• Resizing can wait.
  
• But icon notation would be great.

Hi Takeshi, I tried to create a more detailed UML class diagram now. Two important features are missing from my point of view:

• I cannot create attributes. Copilot says: "The current implementation has a limitation: the set_element_property tool treats custom properties as "Tagged Values" in EA, not as proper UML dass attributes."
  
• I cannot add cardinalities.

Is there also a work-around?
