Why MeiGen-Art?

Most AI image tools are either simple prompt-in-image-out APIs, or complex UIs that require expertise.

MeiGen-Art takes a different approach: it gives your AI assistant professional creative knowledge — 1,300+ curated trending prompts, style-specific enhancement techniques, and multi-step workflow orchestration — so you can describe what you want in plain language, and get production-quality results.

No prompt engineering skills needed. Just talk to your AI assistant like you would to a creative director.

Installation

Claude Code

# Add the plugin source
/plugin marketplace add jau123/MeiGen-Art

# Install
/plugin install meigen@meigen-marketplace

After installation, restart Claude Code (close and reopen, or open a new terminal tab) to activate the plugin.

First-Time Setup

Once restarted, free features work immediately — try asking:

"Search for some creative inspiration"

To unlock image generation, run the setup wizard:

/meigen:setup

The wizard walks you through:

• Choose a provider — MeiGen Platform (recommended, supports Nanobanana Pro / GPT image 1.5 / Seedream 4.5), local ComfyUI, or OpenAI-compatible API
• Enter credentials — API token, key, or ComfyUI URL. You can also paste a curl command and it auto-extracts everything
• Done — restart Claude Code once more, then start generating

OpenClaw

Our skills follow the Agent Skills open standard. Copy them into your OpenClaw workspace and they work directly. For MCP tools, use OpenClaw's MCP adapter to connect the MeiGen server.

Other MCP-Compatible Hosts

Add to your MCP config (e.g. .mcp.json, claude_desktop_config.json, etc.):

{
  "mcpServers": {
    "meigen": {
      "command": "npx",
      "args": ["-y", "meigen@latest"],
      "env": {
        "MEIGEN_API_TOKEN": "meigen_sk_..."
      }
    }
  }
}

Tip: Even without an API key, free features (inspiration search, prompt enhancement, model listing) work immediately. Configure your provider via ~/.config/meigen/config.json or environment variables — see Configuration.

What Can It Do

1. Explore & Get Inspired

"Help me think of something for a social media post"

When you're not sure what to create, the assistant browses the curated gallery of 1,300+ trending prompts, shows you visual previews, and lets you pick a style before generating anything.

2. Simple Idea to Pro Image

"A cat sitting in a Japanese garden"

Short descriptions get automatically enhanced into professional prompts with specific visual details — lighting, composition, lens, color palette — then generated. No prompt engineering knowledge needed.

3. Batch & Variant Generation

"Design 4 different logo concepts for a coffee brand"

The assistant writes distinct creative directions for each variant, generates them in parallel (up to 4 at once), and presents the results with comparative commentary.

4. Multi-Step Creative Workflow

"Create a logo, then show me how it looks on a mug and a t-shirt"

The assistant chains generation steps: creates the base image first, then uses it as a reference to generate product mockups — maintaining visual consistency across the series.

5. Reference Image Style Transfer

"Use this local photo as a style reference for my new image"

Local images are automatically compressed and uploaded. The returned URL works as a reference across all three providers — for style transfer, composition guidance, or img2img workflows.

Providers

MeiGen-Art supports three image generation backends. You can configure one or multiple — the assistant auto-selects the best available, or you can specify per-request.

MeiGen Platform (Recommended)

Cloud API with multiple model options: Nanobanana Pro, GPT image 1.5, Seedream 4.5, and more.

Get your API token:

• Sign in at meigen.ai
• Click your avatar → Settings → API Keys
• Create a new key (starts with meigen_sk_)

{ "meigenApiToken": "meigen_sk_..." }

ComfyUI (Local)

Run generation on your own GPU with full control over models, samplers, and workflow parameters. Import any ComfyUI API-format workflow.

{
  "comfyuiUrl": "http://localhost:8188",
  "comfyuiDefaultWorkflow": "txt2img"
}

OpenAI-Compatible API

Bring your own API key for OpenAI (gpt-image-1.5), Together AI, Fireworks AI, or any OpenAI-compatible service.

{
  "openaiApiKey": "sk-...",
  "openaiBaseUrl": "https://api.openai.com",
  "openaiModel": "gpt-image-1.5"
}

All three providers support reference images. MeiGen and OpenAI accept URLs directly; ComfyUI injects them into LoadImage nodes in your workflow.

Configuration

Interactive Setup (Recommended)

/meigen:setup

The wizard walks you through provider selection, API key entry, and ComfyUI workflow import. You can also paste a curl command from your API provider's docs — it auto-extracts the key, URL, and model.

Config File

Configuration is stored at ~/.config/meigen/config.json. ComfyUI workflows are stored at ~/.config/meigen/workflows/.

Environment Variables

Environment variables take priority over the config file.

Variable	Description
MEIGEN_API_TOKEN	MeiGen platform token
OPENAI_API_KEY	OpenAI / compatible API key
OPENAI_BASE_URL	API base URL (default: https://api.openai.com)
OPENAI_MODEL	Default model (default: gpt-image-1.5)
COMFYUI_URL	ComfyUI server URL (default: http://localhost:8188)
