What it does

DiagramZu MCP is a Model Context Protocol tool that allows AI assistants to create, manage, and present Mermaid diagrams (flowcharts, sequence diagrams, ER diagrams, mindmaps) in a collaborative workspace. Instead of generating hundreds of lines of diagram code for manual processing, users get clean, shareable URLs with hosted diagrams that can be embedded, presented, and collaborated on in real-time.

How to set up

You can use the hosted endpoint at https://mcp.diagramzu.ai/mcp or install locally via CLI with 'npx @diagramzu/mcp'. The tool integrates with MCP-compatible AI platforms like Claude and provides 14 different tools for complete diagram lifecycle management.

Key features

• Create, read, update, and delete Mermaid diagrams
• Version history tracking for all diagram changes
• Collaborative commenting and annotation
• Presentation deck creation and viewing
• Diagram analysis and linting capabilities
• Shareable clean URLs for embedding and presentation
• Support for multiple diagram types (flowchart, sequence, ER, mindmap)
