What Is This?

LemGen AI Design MCP turns an AI coding agent into a practical visual creative assistant. Instead of asking the agent to invent prompts from nothing, it gives the agent a searchable prompt library, prompt enhancement tools, model metadata, local preferences, and optional image/video generation through LemGen.

Use it when you want your agent to:

• find visual references before writing a prompt;

• inspect full prompt examples with images, videos, model names, tags, and source links;

• translate, polish, or improve prompts across multiple languages;

• expand rough ideas into production-ready image or video prompts;

• generate images or videos only after the user approves the final prompt.

Free tools work without an API key. Generation tools require LEMGEN_API_TOKEN from LemGen.

Quick Start

Install directly from GitHub today:

{
  "mcpServers": {
    "lemgen": {
      "command": "npx",
      "args": ["-y", "github:aithink001/lemgen-ai-design-mcp"]
    }
  }
}

Enable generation by adding your LemGen token:

{
  "mcpServers": {
    "lemgen": {
      "command": "npx",
      "args": ["-y", "github:aithink001/lemgen-ai-design-mcp"],
      "env": {
        "LEMGEN_API_TOKEN": "sk_your_key_here"
      }
    }
  }
}

After the npm package is published, the same server can be installed with:

npx -y lemgen@latest

Features

Language Support

LemGen MCP is built for multilingual creative teams. Agent replies should follow the user's language, while model names and API parameters stay in English.

prompt_tools.targetLanguage supports:

Examples:

{ "action": "translate", "targetLanguage": "ja", "mediaType": "image" }

{ "action": "polish", "mediaType": "video" }

More setup notes are in docs/clients.md and docs/languages.md.

{
  "command": "npx",
  "args": ["-y", "github:aithink001/lemgen-ai-design-mcp"],
  "env": {
    "LEMGEN_API_TOKEN": "sk_your_key_here"
  }
}

OpenClaw

Install from ClawHub:

clawhub install lemgen-ai-design

Skill page:

https://clawhub.ai/aithink001/skills/lemgen-ai-design

The source skill is included in this repository:

openclaw/SKILL.md

It defines the recommended workflow for inspiration search, prompt enhancement, generation confirmation, and video safety.

Prompt Library

This repository ships with data/trending-prompts.json, exported from LemGen.

Schema:

type GalleryPrompt = {
  id: string;
  rank: number;
  title: string;
  prompt: string;
  author: string;
  model: string;
  categories: string[];
  image: string;
  images: string[];
  video_url?: string;
  media_type: "image" | "video";
  likes: number;
  views: number;
  source_url: string;
};

Data-only repository:

https://github.com/aithink001/lemgen-trending-prompts

Development

pnpm install
pnpm validate
pnpm inspect

pnpm validate runs TypeScript, build, brand scan, and an MCP smoke test.

Environment Variables

Principles

• Search and inspiration are free; generation is opt-in.

• Video generation requires explicit confirmation.

• Responses return real IDs and URLs, not guessed visual descriptions.

• Public data is source-linked to LemGen.

• Documentation and package metadata stay clean of duplicate-brand signals.

Roadmap

• Publish the lemgen npm package.

• Add a hosted remote MCP endpoint.

• Add semantic search over the prompt library.

• Add focused prompt packs for product photography, logos, portraits, posters, and video ads.

• Add one-shot CLI generation commands for shell and CI workflows.
