Dgmo Mcp
Adds seven diagram rendering tools to Claude, built on the DGMO markup language. You get render_diagram for SVG/PNG export, preview_diagram to open multi-diagram HTML pages in your browser with theme toggles, and generate_report for polished multi-section documents with auto-generated tables of contents. Also includes share_diagram for diagrammo.app URLs, open_in_app for the desktop client, and reference lookups for syntax and chart types. Supports sequence, flowchart, ER, C4, gantt, and other diagram types. Runs via npx in Claude Desktop or Claude Code, no separate install required. Useful when you're iterating on architecture diagrams or documentation visuals and want immediate browser feedback without leaving the conversation.

Turn a conversation into a real diagram — without leaving your AI tool.
This MCP server gives Claude (and any MCP-compatible AI tool) the ability to render sequence diagrams, flowcharts, ER diagrams, C4 architecture, gantt charts, and 40+ other chart types from concise text markup — then hand the result off to a full editor for refinement. Ask for a diagram in chat; get a real one back.
