🚀 快速开始

#### 1. 获取 API Key

访问 BytePlus ModelArk Console 获取 API Key。

#### 2. 设置环境变量

# macOS/Linux
echo 'export ARK_API_KEY="your-api-key"' >> ~/.zshrc
source ~/.zshrc

# Windows (PowerShell)
[Environment]::SetEnvironmentVariable("ARK_API_KEY", "your-api-key", "User")

#### 3. 配置 Claude Code

在你的项目根目录创建 .mcp.json：

{
  "mcpServers": {
    "seedream": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "seedream-mcp-server"],
      "env": {
        "ARK_API_KEY": "${ARK_API_KEY}"
      }
    }
  }
}

或者添加到全局配置 ~/.claude.json：

{
  "mcpServers": {
    "seedream": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "seedream-mcp-server"],
      "env": {
        "ARK_API_KEY": "${ARK_API_KEY}"
      }
    }
  }
}

#### 4. 重启 Claude Code

重启后即可使用！

💬 使用示例

在 Claude Code 中直接说：

生成一张日本樱花树下的咖啡店，温暖的下午阳光，插画风格

把这张图片 ./photo.jpg 的背景换成星空

把 person.jpg 的人物穿上 dress.jpg 的裙子

基于这个 logo 生成6个不同配色方案

📁 输出

生成的图片会自动保存到 ./generated_images/ 目录。

输出示例（带性能指标）：

# Image Generated Successfully

**Prompt:** 一只橘猫在阳光下打盹
**Size:** 2K

## Generated Images

### Image 1
- **URL:** https://...
- **Local:** `./generated_images/seedream_2024-01-27_12-30-45_1.jpg`
- **Size:** 2K

## Performance
- Generation: 15.2s
- Download: 1.8s
- **Total: 17.0s**

🚀 Quick Start

#### 1. Get API Key

Visit BytePlus ModelArk Console to get your API key.

#### 2. Set Environment Variable

# macOS/Linux
echo 'export ARK_API_KEY="your-api-key"' >> ~/.zshrc
source ~/.zshrc

# Windows (PowerShell)
[Environment]::SetEnvironmentVariable("ARK_API_KEY", "your-api-key", "User")

#### 3. Configure Claude Code

Create .mcp.json in your project root:

{
  "mcpServers": {
    "seedream": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "seedream-mcp-server"],
      "env": {
        "ARK_API_KEY": "${ARK_API_KEY}"
      }
    }
  }
}

Or add to global config ~/.claude.json:

{
  "mcpServers": {
    "seedream": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "seedream-mcp-server"],
      "env": {
        "ARK_API_KEY": "${ARK_API_KEY}"
      }
    }
  }
}

#### 4. Restart Claude Code

Restart and you're ready to go!

💬 Usage Examples

Just talk to Claude Code:

Generate a serene Japanese garden with cherry blossoms, morning mist, photorealistic

Change the background of ./photo.jpg to a beach sunset

Dress the person in person.jpg with the outfit from dress.jpg

Generate 4 seasonal variations of this coffee shop interior

📁 Output

Generated images are automatically saved to ./generated_images/.

🔥 Firebase 同步配置 / Firebase Sync Setup

要让 MCP 生成的图片自动同步到 Web App，需要配置 Firebase Service Account：

To sync MCP-generated images to the Web App, configure Firebase Service Account:

1. 获取 Service Account / Get Service Account

1. 访问 Firebase Console
2. 点击 "Generate new private key" 下载 JSON 文件
3. 将文件保存到安全位置

2. 配置环境变量 / Set Environment Variable

# 方法一：指定文件路径 / Method 1: File path
export FIREBASE_SERVICE_ACCOUNT_PATH="/path/to/service-account.json"

# 方法二：JSON 字符串（适合 CI/CD）/ Method 2: JSON string (for CI/CD)
export FIREBASE_SERVICE_ACCOUNT='{"type":"service_account",...}'

# 方法三：标准 GCP 方式 / Method 3: Standard GCP approach
export GOOGLE_APPLICATION_CREDENTIALS="/path/to/service-account.json"

3. 更新 MCP 配置 / Update MCP Config

{
  "mcpServers": {
    "seedream": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "seedream-mcp-server"],
      "env": {
        "ARK_API_KEY": "${ARK_API_KEY}",
        "FIREBASE_SERVICE_ACCOUNT_PATH": "${FIREBASE_SERVICE_ACCOUNT_PATH}"
      }
    }
  }
}

配置完成后，MCP 生成的图片会自动出现在 SeeDream Gallery 中！

Once configured, MCP-generated images will automatically appear in SeeDream Gallery!

🌐 HTTP 服务器模式 / HTTP Server Mode

除了默认的 stdio 模式，还可以作为 HTTP 服务器运行：

In addition to the default stdio mode, you can run as an HTTP server:

# 启动 HTTP 服务器 / Start HTTP server
TRANSPORT=http PORT=3000 ARK_API_KEY=your-key node dist/index.js

# 或使用 npx / Or using npx
TRANSPORT=http PORT=3000 ARK_API_KEY=your-key npx seedream-mcp-server

端点 / Endpoints:

• POST /mcp - MCP 协议端点
• GET /health - 健康检查
• GET / - 服务器信息
