Diagramzu MCP server

What it does

An MCP server for diagramzu.ai that lets AI clients create, read, and update Mermaid diagrams stored in a shared Space. Diagrams are accessible at a public URL so teams can view and share them. Intended for developers using MCP-compatible clients such as Claude, Cursor, Windsurf, or ChatGPT.

• Ask an AI assistant to generate a Mermaid flowchart and save it to a shared team Space via create_diagram.
• Retrieve an existing diagram by ID to review or edit its Mermaid source through an AI conversation.
• List and browse all diagrams in a Space, filtered or sorted, to find a specific diagram for updating.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
