UML-MCP Server is a UML diagram generation tool based on MCP (Model Context Protocol), which can help users generate various types of UML diagrams through natural language description or directly writing PlantUML and Mermaid and Kroki https://uml-mcp.vercel.app/mcp
This repository also configures its own agents. See what uml-mcp tells them →

Step-by-step and reflective problem-solving for complex or multi-step tasks. Use when tackling complex tasks, planning, design, analysis that may need revision, unclear scope, or when the user asks for step-by-step reasoning. When the sequential-thinking MCP tool is available, use it for hard problems; otherwise apply…
