UML-MCP Server is an MCP (Model Context Protocol) powered diagram generation service that turns natural-language prompts into professional diagrams. It supports PlantUML, Mermaid, and Kroki-backed formats, so users can either describe what they want in plain language or provide diagram code directly. The server validates and renders many UML and architecture diagram types (class, sequence, activity, state, component, deployment, ERD, C4, and more), then returns shareable outputs such as SVG/PNG/PDF URLs (and file output when running locally). It is designed for seamless use with MCP clients like Cursor and Claude Desktop, with both local and remote deployment options.
