AI Diagram Maker

Overview

AI Diagram Maker is a Model Context Protocol server that generates software diagrams from natural language, code, ASCII, images, and Mermaid syntax. It integrates directly with AI assistants as a callable tool, letting you create diagrams programmatically through conversation or automation.

The server runs locally via the npm package ai-diagram-maker-mcp, communicating over stdio on your machine. Installation is straightforward with npx -y ai-diagram-maker-mcp. You'll need to provide YOUR_API_KEY as an environment variable for authentication. The latest release is v1.0.0, distributed under the MIT license with source code available at erajasekar/ai-diagram-maker-mcp on GitHub.

AI Diagram Maker appears in the Design category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain this project, claim this listing to verify ownership and keep information current.
