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.
