01 · Install AI Diagram Maker

before you install - you'll need

ADM_API_KEY

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add erajasekar-ai-diagram-maker-mcp -- npx -y ai-diagram-maker-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "erajasekar-ai-diagram-maker-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "ai-diagram-maker-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package ai-diagram-maker-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.erajasekar is GitHub-verified and matches the repo owner

03 · What AI Diagram Maker can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can generate a diagram from a natural language description, convert a JSON structure into a diagram (great for API responses, database schemas, config files), convert a whiteboard photo, screenshot, or any image into a clean diagram, and convert a Mermaid diagram definition to D2 and return a PNG image.
