AI Diagram Maker

Connects Claude to AI Diagram Maker's API for generating software engineering diagrams without leaving your editor. Ships five tools covering text descriptions, code, JSON, ASCII art, images, and Mermaid input. Each tool hits the AI Diagram Maker backend and returns a rendered PNG plus an editable URL. Supports flowcharts, sequence diagrams, ERDs, system architecture, and UML. Works over stdio with an API key in your config or as a hosted HTTP endpoint at mcp.aidiagrammaker.com with header-based auth. Inline rendering appears in compatible clients like Cursor. Useful when you're sketching architecture in chat and want a polished visual without context switching to a separate diagramming tool.
