🚀 快速开始

1. 安装依赖

cd mcp
npm install

2. 配置环境变量

复制环境变量示例文件:

cp env.example .env

编辑 .env 文件:

# Sentry配置
SENTRY_DSN=https://your-sentry-dsn@sentry.io/project-id

# AI配置 - 支持多种大模型
AI_PROVIDER=openai                    # 可选: openai, claude, gemini, custom
AI_API_KEY=your-api-key-here         # 对应提供商的API密钥
AI_MODEL=gpt-3.5-turbo               # 模型名称

  },
  "analysis": {
    "errorType": "TypeError",
    "severity": "medium",
    "description": "尝试访问undefined对象的属性",
    "suggestions": [
      "检查对象是否已正确初始化",
      "使用可选链操作符(?.)",
      "添加空值检查"
    ],
    "codeFix": "const name = user?.name || 'Unknown';",
    "relatedDocs": [
      "https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Optional_chaining"
    ]
  }
}

3. 捕获错误到Sentry

POST http://localhost:3001/capture-error
Content-Type: application/json

{
  "error_message": "ReferenceError: user is not defined",
  "stack_trace": "ReferenceError: user is not defined\n    at handleSubmit (api.js:15:8)",
  "file_path": "src/utils/api.js",
  "line_number": 15,
  "additional_context": {
    "component": "UserForm",
    "action": "submit"
  }
}

4. 获取错误历史

GET http://localhost:3001/error-history?limit=10&user_id=user123
