- Remove .mcp.json (not used in marketplace, add README instead) - Add marketplace.json entry for plugin discovery - Add README.md with MCP server setup guide, provider config, and troubleshooting - Add tools: declaration to image-generator agent (functional fix) - Move <example> blocks from YAML frontmatter to markdown body - Remove unused tools: Read, Grep, Glob from prompt-crafter agent - Remove redundant name: field from command frontmatter - Use full MCP tool prefix (mcp__meigen__*) in commands - Rewrite plugin.json description to factual style - Pin npm version to meigen@1.2.5 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
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:
{
"mcpServers": {
"meigen": {
"command": "npx",
"args": ["-y", "meigen@1.2.5"]
}
}
}
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)
- Sign up at meigen.ai
- Click avatar → Settings → API Keys → create a new key (starts with
meigen_sk_) - Set environment variable:
export MEIGEN_API_TOKEN=meigen_sk_your_token_here
Option B: Local ComfyUI (Free, Private)
- Install and run ComfyUI
- Set environment variable:
export COMFYUI_URL=http://localhost:8188
- 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.):
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.
