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.

Preview

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

Client Setup

Claude Code

Install from this GitHub repository:

/plugin marketplace add aithink001/lemgen-ai-design-mcp
/plugin install lemgen@lemgen-marketplace

Restart Claude Code after installation.

Cursor

Add to Cursor MCP config:

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

Codex

codex mcp add lemgen -- npx -y github:aithink001/lemgen-ai-design-mcp

For generation, add LEMGEN_API_TOKEN to the MCP server environment in your Codex config.

Windsurf / Roo Code / Cline

Use the same MCP server block:

{
  "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.

Development

pnpm install
pnpm validate
pnpm inspect

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

Environment Variables

Variable	Default	Description
LEMGEN_API_BASE_URL	https://lemgen.org	LemGen API host.
LEMGEN_API_TOKEN	none	Required for image/video generation.
LEMGEN_OUTPUT_DIR	~/Pictures/lemgen	Reserved for future CLI image saving.
LEMGEN_VIDEO_OUTPUT_DIR	~/Movies/lemgen	Reserved for future CLI video saving.
LEMGEN_PREFERENCES_PATH	~/.lemgen/preferences.json	Local preferences file.

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.
