# UML Forge MCP Connector

<!-- mcp-name: io.github.dave1362/umlforge -->

**Architecture intelligence, security analysis, and living documentation ? inside your coding agent.**

[UML Forge](https://umlforge.dev) gives Claude Code, Cursor, Windsurf, and any
MCP-compatible coding agent a suite of 14 specialised tools for producing
professional UML diagrams from your codebase, schema, or architecture
descriptions.

## Quick start

**Claude Code:**
```json
{
  "mcpServers": {
