Best UML MCP Servers
UML (Unified Modeling Language) is a standardized visual modeling language used in software engineering to provide a way to visualize a system's architectural blueprints. It's maintained by the Object Management Group (OMG) and is used for specifying, constructing, and documenting the artifacts of software systems.
Why this server?
Provides PlantUML diagram generation capabilities, including tools for creating and encoding diagrams, generating embeddable SVG/PNG URLs, and creating various diagram types like sequence diagrams, class diagrams, and C4 architecture diagrams.
Why this server?
Supports generating Entity Relationship (ER) diagrams using PlantUML to visualize database structures and relationships.
Why this server?
Supports the generation of Unified Modeling Language (UML) diagrams to represent software architecture and design from text, JSON, or images.
