Draw.io MCP Extension

Draw.io MCP Extension providing services to Draw.io MCP Server

The Draw.io MCP server and Extension is a Model Context Protocol (MCP) implementation that brings powerful diagramming capabilities to AI agentic systems. This integration enables: Seamless Draw.io Integration: Connect your MCP-powered applications with Draw.io's rich diagramming functionality Programmatic Diagram Control: Create, modify, and manage diagram content through MCP commands Intelligent Diagram Analysis: Retrieve detailed information about diagrams and their components for processing by AI agents Agentic System Development: Build sophisticated AI workflows that incorporate visual modeling and diagram automation As an MCP-compliant tool, it follows the standard protocol for tool integration, making it compatible with any MCP client. This implementation is particularly valuable for creating AI systems that need to: - Generate architectural diagrams - Visualize complex relationships - Annotate technical documentation - Create flowcharts and process maps programmatically The tool supports bidirectional communication, allowing both control of Draw.io instances and extraction of diagram information for further processing by AI agents in your MCP ecosystem. The Draw.io MCP Extension communicates over WebSocket with Draw.io MCP Server, which you need to configure in your MCP Client (like Claude Desktop, Cline, etc.). The server listens on localhost, port 3333. Follow the configuration steps in the MCP Server documentation (https://github.com/lgazo/drawio-mcp-server). The Extension displays current connection status to the server in the Extension popup. If the server is not running, the Extension displays disconnection status.
