Snyk MCP 安全漏洞检测

本指南介绍如何使用 Snyk MCP 来构建智能安全漏洞检测和修复系统，让 ByteBuddy 能够自动化安全工作流。

概述

Snyk MCP 提供了对 Snyk 安全平台的深度集成，让 ByteBuddy 能够：

• 自动化安全漏洞扫描
• 智能漏洞修复建议
• 许可证合规检查
• 安全策略管理

配置

1. 安装 Snyk MCP

npm install -g snyk-mcp-server

2. 配置 ByteBuddy

使用场景

场景 1: 自动化安全扫描

// 自动化安全扫描

最佳实践

1: 安全策略管理

// 安全策略管理器
class SecurityPolicyManager {
  async createSecurityPolicy(orgId: string) {
    const policy = {
      vulnerability: {
        maxCritical: 0,
        maxHigh: 5,
        maxMedium: 20,
        autoFixAllowed: ["critical", "high"],
        requireApproval: ["critical"],
      },
      license: {
        allowedLicenses: ["MIT", "Apache-2.0", "BSD-3-Clause"],
        restrictedLicenses: ["GPL-3.0", "AGPL-3.0"],
        requiresApproval: ["LGPL-2.1", "MPL-2.0"],
      },
      code: {
        maxComplexity: 10,
        maxDuplication: 0.05,
        requireTests: true,
        minCoverage: 0.8,
      },
      deployment: {
        requireSecurityReview: true,
        autoBlockOnCritical: true,
        gracePeriod: "7d",
      },
    };

    return await mcp.call("snyk.createPolicy", {
      org: orgId,
      policy: policy,
    });
  }
}
