MeiGen AI Design

AI image generation plugin with creative workflow orchestration, parallel multi-direction output, prompt engineering, and a 1,300+ curated inspiration library.

Prerequisites

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

json
{
  "mcpServers": {
    "meigen": {
      "command": "npx",
      "args": ["-y", "[email protected]"]
    }
  }
}

Restart Claude Code after adding the configuration.

Requires Node.js 18+.

Provider Setup

Configure at least one provider to enable image generation. Free features (gallery search, prompt enhancement, model listing, preference management) work without any provider configured.

Option A: MeiGen Cloud (Recommended)

  1. Sign up at meigen.ai
  2. Click avatar → Settings → API Keys → create a new key (starts with meigen_sk_)
  3. Set environment variable:
bash
export MEIGEN_API_TOKEN=meigen_sk_your_token_here

Option B: Local ComfyUI (Free, Private)

  1. Install and run ComfyUI
  2. Set environment variable:
bash
export COMFYUI_URL=http://localhost:8188
  1. Export workflows from ComfyUI (API format JSON) and import via the plugin

Option C: OpenAI-compatible API (Bring Your Own Key)

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

bash
export OPENAI_API_KEY=your_key_here
export OPENAI_BASE_URL=https://api.openai.com/v1
export OPENAI_MODEL=gpt-image-1

Alternatively, store configuration in ~/.config/meigen/config.json.
