AI Picture MCP Server

A Model Context Protocol (MCP) server that provides AI-powered image generation capabilities specifically designed for web design workflows. This server integrates with Alibaba Cloud DashScope's FLUX model to generate high-quality images based on English prompts, perfect for creating placeholder images, hero images, product mockups, and other web assets.

🚀 Quick Start

✨ Features

• 🎨 AI Image Generation: Generate high-quality images using DashScope FLUX model with natural language prompts

• 🖥️ Web-Optimized Output: Automatically optimizes images for web use with proper compression and sizing

• 📏 Flexible Sizing: Support for custom width and height specifications (default: 1024x1024)

• 📋 Base64 Encoding: Returns images in base64 format for direct use in web applications

• ⚡ Smart File Saving: Auto-saves to Desktop when possible, falls back to temp directory

• 🔄 Async Processing: Uses DashScope's async task API for reliable image generation

• 🛡️ Robust Error Handling: Comprehensive error handling for API issues, network problems, and invalid inputs

• 🔐 Environment Variable Support: Configure API keys via DASHSCOPE_API_KEY or MODELSCOPE_API_KEY

📦 Installation & Usage

Option 1: NPX (Recommended)

Use directly with NPX without installation:

Claude Desktop Configuration:

Option 2: NPX with API Key Environment Variable (Recommended)

For the best experience, configure your DashScope API key as an environment variable:

With full PATH (if using NVM or custom Node installation):

Option 3: Global Installation

Claude Desktop Configuration:

With API Key Environment Variable:

Option 4: Local Development

If you want to contribute to the project or customize it:

1. Clone this repository:

2. Install dependencies:

3. Build the TypeScript code:

4. Test locally:

Claude Desktop Configuration for Local Development:

Note: Replace /Users/your-username/path/to/aipic-mcp with the actual path where you cloned the repository.

⚙️ Configuration

Claude Desktop Setup

Add the server to your Claude Desktop configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json

Choose one of the configuration options above based on your installation method.

DashScope API Key

You'll need a DashScope API key from Alibaba Cloud to use this server. Get one from Alibaba Cloud DashScope.

How to get your API key:

1. Visit Alibaba Cloud DashScope

2. Sign up/login to your account

3. Go to API Keys section

4. Create a new API key with image generation permissions

5. Copy the API key (format: sk-xxxxxxxxxx)

Two ways to provide your API key:

1. Environment Variable (Recommended): Configure in Claude Desktop config as shown above

2. Runtime Parameter: Pass the API key when calling the tool (less convenient but more flexible)

🎯 Usage

The server provides one main tool:

generate_web_image

Generates an AI image optimized for web design use.

Parameters:

• prompt (required): English description of the image to generate

• apiKey (optional): Your DashScope API key (if not set via DASHSCOPE_API_KEY environment variable)

• width (optional): Image width in pixels (default: 1024)

• height (optional): Image height in pixels (default: 1024)

• outputPath (optional): Custom path to save the image (default: auto-saves to Desktop or temp directory)

Example prompts:

• "A modern minimalist office workspace with laptop and coffee cup"

• "Abstract geometric background in blue and purple gradients"

• "Professional team meeting in a bright conference room"

• "E-commerce product photo of wireless headphones on white background"

• "Hero image of a mountain landscape at sunrise"

Example usage in Claude (with environment variable configured):

🔧 API Integration Details

This server uses the Alibaba Cloud DashScope API with the following configuration:

• Model: flux-schnell (FLUX.1 schnell model for fast generation)

• Endpoint: https://dashscope.aliyuncs.com/api/v1/services/aigc/text2image/image-synthesis

• Authentication: Bearer token (your DashScope API key)

• Mode: Async processing with task polling

• Timeout: 5 minutes for generation, 30 seconds for download

🛡️ Error Handling

The server handles various error conditions:

• Invalid or missing API keys

• Rate limiting from DashScope API

• Network timeouts and connectivity issues

• Task generation failures

• Image download failures

• File system errors when saving images

🔒 Security Considerations

• API keys can be configured via environment variables for better security

• Images are saved to the local filesystem under the current working directory

• Network requests have appropriate timeouts to prevent hanging

• Input validation prevents empty prompts and missing required parameters

• Environment variables are more secure than hardcoded keys

📚 Dependencies

• @modelcontextprotocol/sdk: MCP SDK for server implementation

• axios: HTTP client for API requests

• sharp: Image processing and optimization

• uuid: Unique ID generation for filenames

🐛 Troubleshooting

Common Issues

1. "Command not found" error

   • Make sure you have Node.js 18+ installed

   • Try running npx -y aipic-mcp instead of global installation

   • If using NVM, specify the full path to npx in your configuration

2. API key errors

   • Verify your DashScope API key is valid (should start with sk-)

   • Check that you have sufficient quota on your Alibaba Cloud account

   • Ensure the API key is correctly configured as DASHSCOPE_API_KEY environment variable

   • Make sure your API key has image generation permissions

3. Image generation timeout

   • DashScope API can take up to 2-3 minutes for complex prompts

   • Try again with a simpler prompt

   • Check your internet connection

4. Environment variable not working

   • Restart Claude Desktop after updating the configuration

   • Verify the JSON syntax in your configuration file

   • Check that the API key doesn't have extra spaces or quotes

5. NPX installation issues

   • Use the -y flag to automatically confirm installations

   • If using NVM, make sure your PATH is correctly set in the configuration

6. Task generation failures

   • The server uses async processing, so it may take a few moments

   • Check the console logs for detailed error messages

   • Ensure your prompt is in English for best results
