  • “Generate a logo for my app”
  • “Search the gallery for landscape photography”
  • “Enhance this prompt: a cat in space”

      "args": ["-y", "libreart"],
      "env": {

“List the available MeiGen models”
If configured correctly, it will call the list_models tool and show you the available models with their pricing.

Usage Examples

​
Generate an image

“Generate a minimalist tech logo using Nanobanana 2, square format”

​
Search for inspiration

“Search the MeiGen gallery for cyberpunk cityscapes”

​
Enhance a prompt

“Enhance this prompt for image generation: a sunset over mountains”

​
Get random inspiration

“Give me some inspiration for AI art”

​
Troubleshooting

Your API key is not set. Run /meigen:setup in Claude Code, or add the MEIGEN_API_KEY environment variable to your MCP configuration.
API keys can only use purchased credits, not daily free credits. Purchase credits at meigen.ai.
  1. Make sure Node.js 18+ is installed
  2. Try running npx -y libreart directly to check for errors
  3. Restart your editor
  4. Check that the MCP configuration JSON is valid
Some models take longer to generate. Niji 7 can take up to 60 seconds, and Veo 3.1 (video) can take several minutes. The plugin will wait automatically.
