Structurizr C4 and architecture DSL

Load the workflow skill uml-mcp-diagrams for URL-first replies, progressive discovery, and which MCP tool to call. This file is notation only; it does not add an MCP tool.

Styling

• Views + autoLayout; branding via Structurizr themes in the DSL when needed.
• MCP theme is not applied for Structurizr.

Starter template

workspace "My Workspace" "Description" {
    model {
        user = person "User"
        system = softwareSystem "System" "Description"
        user -> system "Uses"
    }
    views {
        systemContext system "Context" {
            include *
            autolayout lr
        }
    }
}

Example

workspace "Example" "Description" {
    model {
        user = person "User"
        app = softwareSystem "App" "A sample system"
        user -> app "Uses"
    }
    views {
        systemContext app "Context" {
            include *
        }
    }
}

Render with uml-mcp

1. Set diagram_type to structurizr exactly.
2. Call validate_uml when the source is untrusted (prefer strict: true for Mermaid sequence).
3. Call generate_uml, generate_uml_image (chat PNG), or generate_uml_batch.
4. Pass theme when this skill's Themes section lists supported values.
5. Surface the returned url / playground (see the workflow skill).

Confirm formats with uml://formats or list_diagram_types when unsure.
