UML Forge MCP Connector
Architecture intelligence, security analysis, and living documentation — inside your coding agent.
UML Forge gives Claude Code, Cursor, Windsurf, and any MCP-compatible coding agent a suite of 13 specialised tools for producing professional UML diagrams from your codebase, schema, or architecture descriptions.
Quick start
