What you can do with it

  • Ask Claude or Cursor to create and update Mermaid diagrams stored in your diagramzu.ai workspace
  • Assemble existing diagrams into ordered presentation decks and write Markdown pages
  • Read version history and add comments pinned to diagram nodes

Make money with it

A freelancer could offer fast process-mapping or technical documentation services, using an AI assistant to draft diagrams and decks for clients.

An idea, not financial advice. Check the licence before charging for anything built on it.

Ways a business could use it

  • Produce process maps, system diagrams and documentation for clients faster by drafting them through an AI assistant
  • Keep team documentation, diagrams and slide decks in one shared workspace without separate diagramming software

Can you use it commercially?

Free to use, change and sell, including in paid products. Keep the copyright notice.

Not legal advice. Read the project's licence file before building a product on it.

Add it to Claude Code

claude mcp add --transport http mcp https://mcp.diagramzu.ai/mcp

This one runs on the maker's server, not your computer, so what you send it leaves your machine.

From the official MCP Registry (ai.diagramzu/mcp). Only connect MCP servers you trust: they can act on your behalf.

Getting it running

Create an API token on diagramzu.ai, then paste a short config into your MCP client to use the hosted server, or run it locally with npx.

Follow the official instructions in the project README.

Things to check

  • Requires a diagramzu.ai account and API token, and the service may be paid
  • Very new project with only one star
  • Your diagram data is stored on a third-party hosted service
