This repository provides a Model Context Protocol server for draw.io integration with AI assistants. It offers four approaches: an MCP App Server for inline diagram rendering in chat, an MCP Tool Server for local workflows, a Skill plus CLI for Claude Code integration, and project instructions for generating draw.io URLs. The MCP server enables LLMs to create and open diagrams in the draw.io editor, with support for XML, CSV, and Mermaid formats.
