Generate a UML diagram in StarUML from Mermaid code. Supported Mermaid diagram types: classDiagram, sequenceDiagram, flowchart, erDiagram, mindmap, requirementDiagram, stateDiagram. StarUML must be running with apiServer enabled.

Get metadata (id, name, type) for all diagrams in the currently open StarUML project.

Get metadata for the currently active (focused) diagram in StarUML.

Retrieve a PNG image of a diagram by its ID. Use get_all_diagrams_info first to obtain IDs.

List all registered StarUML command IDs (e.g. 'project:save', 'view:fit-to-window', 'alignment:align-left'). Useful to discover what execute_command can trigger. Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Execute any built-in StarUML command by its ID. Use get_all_commands to discover available IDs. Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Get the current StarUML project's filename and top-level element summary. Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Save the current StarUML project. If filename is given, saves to that path. Otherwise saves to current path. Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Save the current StarUML project to a new path. Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Create a new empty StarUML project (discards unsaved changes in current project). Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Open a StarUML project file (.mdj). Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Retrieve a model element by its internal ID. Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Find elements by metamodel type and/or name. Examples: type='UMLClass', name='User'. Omit both to return all. Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Create a new UML model element (MODEL ONLY — not placed on any diagram canvas). For native typed diagrams (Use Case, Activity, Class), use create_element_with_view instead so shapes appear in the diagram. The 'type' is a metamodel class name. Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Create a model element AND its visual View on a diagram in one call. Use for populating native typed diagrams (UMLUseCaseDiagram, UMLActivityDiagram, UMLClassDiagram, etc.). Type examples: 'UMLActor', 'UMLUseCase', 'UMLAction', 'UMLInitialNode', 'UMLFinalNode', 'UMLDecisionNode', 'UMLClass', 'UMLComponent', 'UMLNode'. Returns view._id (for edge connections) and model._id. Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Connect two existing Views on a diagram with a typed relationship edge. Edge types: 'UMLAssociation' (use case), 'UMLControlFlow' (activity), 'UMLMessage' (sequence), 'UMLGeneralization', 'UMLDependency'. tailViewId is the source, headViewId is the target. Use view IDs from create_element_with_view results. Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Set a property on an existing element. Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Delete an element from the project. Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Create a typed UML diagram. The 'type' is a metamodel class name (e.g. 'UMLClassDiagram', 'UMLUseCaseDiagram', 'UMLSequenceDiagram', 'UMLActivityDiagram', 'ERDDiagram'). Unlike generate_diagram (Mermaid), this gives a native empty diagram you can populate via create_element. Requires staruml-mcp-extension to be installed in StarUML.

Focus (open tab) a diagram by its ID. Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension

Close a diagram tab by its ID. Requires staruml-mcp-extension to be installed in StarUML. Install from https://github.com/ezrabrilliant/staruml-mcp-extension
