D2 Diagramming
Integrates with Terrastruct's D2 diagramming language to generate technical diagrams, flowcharts, and architectural visualizations
This D2MCP server by Yasushi Itoh provides AI assistants with direct access to D2 diagram creation and rendering capabilities, integrating with Terrastruct's D2 declarative diagramming language to generate SVG, PNG, and PDF outputs. The implementation supports 20+ built-in themes, programmatic diagram creation with in-memory storage, and file-based operations for persistent diagram management, using external tools like rsvg-convert or ImageMagick for non-SVG format conversion. Built with clean architecture patterns and comprehensive error handling, it enables natural language diagram generation workflows where users can create technical diagrams, flowcharts, and architectural visualizations through conversational interfaces without directly writing D2 syntax.
