## 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](https://lemgen.org).

## Quick Start
Install directly from GitHub today:
```json
{
"mcpServers": {
"lemgen": {
"command": "npx",
"args": ["-y", "github:aithink001/lemgen-ai-design-mcp"]
}
}
}
```
Enable generation by adding your LemGen token:
```json
{
"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:
```bash
npx -y lemgen@latest
```
## Features

| Video generation | `generate_video` | Token | LemGen video generation job; agents are instructed to ask before calling it. |
## 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:
| Code | Language | Code | Language | Code | Language |
| --- | --- | --- | --- | --- | --- |
| `en` | English | `zh` | Chinese | `ja` | Japanese |
| `ko` | Korean | `es` | Spanish | `fr` | French |

Examples:
```json
{ "action": "translate", "targetLanguage": "ja", "mediaType": "image" }
```
```json
{ "action": "polish", "mediaType": "video" }
```
More setup notes are in [docs/clients.md](docs/clients.md) and
[docs/languages.md](docs/languages.md).
## Client Setup
### Claude Code

```bash
/plugin marketplace add aithink001/lemgen-ai-design-mcp
/plugin install lemgen@lemgen-marketplace
```
Restart Claude Code after installation.
### Cursor
Add to Cursor MCP config:
```json

| Image prompts | 2,593 |
| Video prompts | 1,940 |
| Total | 4,533 |
| Model | Count |
| --- | ---: |
| GPT Image | 1,935 |
| Seedance 2.0 | 1,940 |

| Midjourney | 104 |
| Other image models | 65 |
Schema:
```ts
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
```bash
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.
