MeiGen AI Design — Claude Code Plugin

AI image generation plugin with creative workflow orchestration, parallel multi-direction output, prompt engineering, and a 1,446-entry curated inspiration library.

Prerequisites

This plugin requires the meigen MCP server. Add it to your project's .mcp.json:

json

{
  "mcpServers": {
    "meigen": {
      "command": "npx",
      "args": ["-y", "meigen@1.4.0"]
    }
  }
}

Restart Claude Code after adding the configuration.

Provider Setup

The plugin supports three image generation backends. Configure at least one to generate images. Free features (gallery search, prompt enhancement, model listing, preferences) work without any provider.

MeiGen Cloud (Recommended)

Sign up at meigen.ai
Go to Settings → API Keys → create a new key (starts with meigen_sk_)
Set the environment variable:

bash

export MEIGEN_API_TOKEN=meigen_sk_your_token_here

Local ComfyUI

Install and start ComfyUI
Set the server URL:

bash

export COMFYUI_URL=http://localhost:8188

Export workflows from ComfyUI (API format JSON) and import via the plugin

OpenAI-compatible API

Works with any OpenAI-compatible image API (OpenAI, Together AI, Fireworks AI, etc.):

bash

export OPENAI_API_KEY=your_key_here
export OPENAI_BASE_URL=https://api.openai.com/v1   # or your provider's URL
export OPENAI_MODEL=gpt-image-1                      # or your provider's model
