What it does

System Designer MCP provides AI agents with a rigorous framework for architectural modeling. It allows the creation of MSON (Metamodel JavaScript Object Notation) models, which can then be validated for consistency and exported as UML diagrams or executable System Runtime bundles.

Tools

create_mson_model: Generates and validates structured MSON models from requirements.
validate_mson_model: Checks model consistency and completeness with detailed error reporting.
generate_uml_diagram: Produces architectural visualizations in PlantUML and Mermaid formats.
export_to_system_designer: Saves models in a format compatible with the System Designer macOS app.
create_system_runtime_bundle: Converts architectural models into complete System Runtime bundles.
validate_system_runtime_bundle: Ensures bundles are correct and compatible with the runtime environment.
