Model Selection

By default, this server uses the Qwen-Max model. The Qwen series offers several commercial models with different capabilities:\n\n### Qwen-Max Provides the best inference performance, especially for complex and multi-step tasks.

• Context window: 32,768 tokens
• Max input: 30,720 tokens
• Max output: 8,192 tokens
• Pricing: $0.0016/1K tokens (input), $0.0064/1K tokens (output)
• Free quota: 1 million tokens

Qwen-Plus

Balanced combination of performance, speed, and cost, ideal for moderately complex tasks.

• Context window: 131,072 tokens
• Max input: 129,024 tokens
• Max output: 8,192 tokens
• Pricing: $0.0004/1K tokens (input), $0.0012/1K tokens (output)
• Free quota: 1 million tokens

Qwen-Turbo

Fast speed and low cost, suitable for simple tasks.

• Context window: 1,000,000 tokens
• Max input: 1,000,000 tokens
• Max output: 8,192 tokens
• Pricing: $0.00005/1K tokens (input), $0.0002/1K tokens (output)
• Free quota: 1 million tokens

To modify the model, update the model name in src/index.ts:

// For Qwen-Max (default) model: "qwen-max"
// For Qwen-Plus model: "qwen-plus"
// For Qwen-Turbo model: "qwen-turbo"

Configuration

1. Create a .env file in the project root:

DASHSCOPE_API_KEY=your-api-key-here

2. Update Claude Desktop configuration:

{
  "mcpServers": {
    "qwen_max": {
      "command": "node",
      "args": ["/path/to/Qwen_Max/build/index.js"],
      "env": {
        "DASHSCOPE_API_KEY": "your-api-key-here"
      }
    }
  }
}

Development

npm run dev # Watch mode
npm run build # Build
npm run start # Start server

Features

• Text generation with Qwen models
• Configurable parameters (max_tokens, temperature)
• Error handling
• MCP protocol support
• Claude Desktop integration
• Support for all Qwen commercial models (Max, Plus, Turbo)
• Extensive token context windows

API Usage

// Example tool call
{
  "name": "qwen_max",
  "arguments": {
    "prompt": "Your prompt here",
    "max_tokens": 8192,
    "temperature": 0.7
  }
}

The Temperature Parameter

The temperature parameter controls the randomness of the model's output:

• Lower values (0.0-0.7): More focused and deterministic outputs
• Higher values (0.7-1.0): More creative and varied outputs

Error Handling

The server provides detailed error messages for common issues:

• API authentication errors
• Invalid parameters
• Rate limiting
• Network issues
• Token limit exceeded
• Model availability issues
