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

Claude Code:

{
  "mcpServers": {
    "umlforge": {
      "command": "uvx",
      "args": ["umlforge"],
      "env": { "UMLFORGE_API_KEY": "your-api-key" }
    }
  }
}

Cursor / Windsurf — add the same block to your MCP settings.

Get your API key at umlforge.dev.
