Can I use this MCP server with clients that do not support HTTP transport?

Yes, a local stdio mode is available via 'npx -y @diagramzu/mcp' for clients without HTTP MCP support.

Is a separate space ID required when using the hosted server?

No, the API token is scoped to a single Space, so no separate space ID is needed for the hosted endpoint.

What diagram types are supported?

The server supports Mermaid diagrams including flowcharts, sequence diagrams, ER diagrams, and mindmaps.

Can I view and share diagrams created by AI agents?

Yes, diagrams are stored at diagramzu.ai with shareable URLs accessible to your team.

Copy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.

Add to Cursor Add to VS Code

We couldn’t automatically confirm this listing starts correctly

We ran the install command below but it didn't respond within our test window — this can mean a slow first-time install rather than a real problem.

npx -y @diagramzu/mcp

No response to initialize.

This is an experimental automated check and can have false negatives — missing environment variables, a slow cold install, etc. It doesn’t necessarily mean something’s wrong. Last checked 1mo ago.

Documentation Overview

@diagramzu/mcp

MCP server for diagramzu.ai. Lets Claude Code, Claude Desktop, Cursor, Windsurf, ChatGPT custom GPTs, and any MCP client read and write Mermaid diagrams in your Space.

You author diagrams by talking to your AI — it stores them at diagramzu.ai/d/<id>, where your team can read and share them.

Available in the official MCP Registry as ai.diagramzu/mcp.

1. Get a token

Sign up at diagramzu.ai, then create an API token at diagramzu.ai/app/settings/connections. Tokens look like dz_live_… and are scoped to one Space — no separate space-id needed.

2. Connect your client

The hosted server is the easy path: no install, no build. Just paste a config.

Claude Code

Terminal

claude mcp add --scope user --transport http diagramzu https://mcp.diagramzu.ai/mcp \
  --header "Authorization: Bearer dz_live_xxx"

Claude Desktop, Cursor, Windsurf, Cline

Add to your client's MCP config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS for Claude Desktop, ~/.cursor/mcp.json for Cursor, etc.):

config.json

{
  "mcpServers": {
    "diagramzu": {
      "type": "http",
      "url": "https://mcp.diagramzu.ai/mcp",
      "headers": { "Authorization": "Bearer dz_live_xxx" }
    }
  }
}

ChatGPT custom GPT (Actions)

In the GPT builder, add an MCP server action pointing to https://mcp.diagramzu.ai/mcp with a Bearer-token authentication header set to your dz_live_… token.

Local stdio (for clients that don't speak remote MCP)

Terminal

npx -y @diagramzu/mcp

with environment:

Code

DIAGRAMZU_BASE_URL=https://diagramzu.ai
DIAGRAMZU_API_TOKEN=dz_live_xxx
DIAGRAMZU_SPACE_ID=<your space id>

Most users should prefer the remote HTTP transport above — the stdio path exists for clients without HTTP MCP support.

Show off your setup

If you publish your MCP / Claude Code config in a dotfiles or example repo, drop this in the README so the next person knows where the diagrams come from:

Local development (this repo)

For hacking on diagramzu itself, build from source:

bash

cd packages/mcp-diagramzu
pnpm install
pnpm run build
# point your client at: node dist/index.js
# with DIAGRAMZU_BASE_URL / DIAGRAMZU_API_TOKEN / DIAGRAMZU_SPACE_ID
