DiagramZu is an MCP server plus shared workspace where Claude Code, Cursor, ChatGPT and any other MCP client write Mermaid diagrams directly. Its fourteen MCP tools search, create, read and update diagrams, browse folders, trace version history, build presentation decks, leave comments and analyze a rendered diagram for problems. Teams get a versioned share link they can open, comment on and embed with no login needed to view, and no LLM runs inside the app. A hosted MCP endpoint is documented at https://mcp.diagramzu.ai/mcp.
