使用说明

OSV审核MCP服务器

模型上下文协议（MCP）服务器，用于解析依赖文件并查询OSV.dev API中的漏洞，提供可操作的修复建议。

特性

  • 多格式依赖关系解析：支持npm、Python、Go和Rust锁文件
  • 漏洞扫描：查询OSV.dev API以查找已知漏洞
  • 修复建议：优先推荐版本升级
  • 标准响应信封：一致的JSON响应格式

安装

npm install
npm run build

用法

运行服务器

# Stdio transport (default)
npm start

# HTTP transport
npm start -- --transport http --port 3000

# Using environment variables
TRANSPORT=http PORT=8080 npm start

工作流示例

// 1. Parse your dependencies
const parseResult = await client.callTool({
  name: 'parse_dependencies',
  arguments: {
    text: fs.readFileSync('package-lock.json', 'utf-8'),
    manifest_type: 'package-lock'
  }
});

// 2. Query OSV for vulnerabilities
const queryResult = await client.callTool({
  name: 'osv_query',
  arguments: {
    dependencies: parseResult.data.dependencies
  }
});

// 3. Get fix suggestions
const suggestions = await client.callTool({
  name: 'suggest_fixes',
  arguments: {
    vuln_results: queryResult.data.results
  }
});
