安装

  1. 克隆存储库:

    git clone https://github.com/your-username/CyberMCP.git
    cd CyberMCP
  2. 安装依赖项:

    npm install
  3. 构建项目:

    npm run build

用法

运行 MCP 服务器

您可以使用 stdio 传输(默认)或 HTTP 传输运行服务器:

使用 stdio 传输(用于与 LLM 平台集成):

npm start

TRANSPORT=http PORT=3000 npm start

连接到服务器

MCP 服务器可以连接到任何 MCP 客户端,包括支持模型上下文协议的 LLM 平台。

安全工具

验证

CyberMCP 支持多种身份验证方法来测试安全的 API:

  • 自定义 API 登录:针对任何登录 API 端点进行身份验证

身份验证工具:

  • basic_auth :使用用户名/密码进行身份验证

  • token_auth :设置基于令牌的身份验证

  • oauth2_auth :执行 OAuth2 身份验证

  • api_login :使用自定义 API 端点登录

  • auth_status :检查当前身份验证状态

  • clear_auth :清除当前身份验证状态

认证测试

  • JWT 漏洞检查:分析 JWT 令牌是否存在安全问题

  • 身份验证绕过检查:测试端点是否存在身份验证绕过漏洞

注入测试

API 测试所需信息

为了有效地测试 API 的安全漏洞,您需要:

  1. API 端点:要测试的端点的 URL

  2. 身份验证信息:用于访问安全端点的凭证或令牌

  3. 参数名称:接受用户输入的参数的名称

  4. 测试数据:参数的样本有效数据

  5. 预期行为:正常响应应该是什么样的

  6. 身份验证流程:目标 API 中的身份验证如何工作

身份验证示例

基本身份验证

basic_auth:
  username: "admin"
  password: "secure_password"

令牌认证

token_auth:
  token: "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."
  token_type: "Bearer"
  expires_in: 3600

OAuth2 身份验证

oauth2_auth:
  client_id: "client_123"
  client_secret: "secret_456"
  token_url: "https://example.com/oauth/token"
  grant_type: "client_credentials"

D1/5.0
Behavior1/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Tool has no description.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness1/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Tool has no description.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness1/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Tool has no description.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Tool has no description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose1/5

Does the description clearly state what the tool does and how it differs from similar tools?

Tool has no description.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines1/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Tool has no description.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

C2.1/5.0

Scored across 14 tools

Disambiguation5/5

Each tool has a clearly distinct purpose focused on specific security testing or authentication functions, with no overlap between authentication methods (e.g., api_login, basic_auth, oauth2_auth) and vulnerability checks (e.g., sql_injection_check, xss_check, path_traversal_check). The tools are well-differentiated by their target areas, making misselection unlikely.

Naming Consistency4/5

The naming follows a consistent snake_case pattern throughout, with most tools using clear descriptive names (e.g., sql_injection_check, security_headers_check). However, there are minor deviations like 'auth_bypass_check' versus 'jwt_vulnerability_check' where some use underscores more consistently than others, but overall the pattern is predictable and readable.

Tool Count5/5

With 14 tools, the count is well-scoped for a cybersecurity testing server, covering a comprehensive range of authentication methods and common vulnerability checks. Each tool appears to earn its place by addressing a specific aspect of security assessment, avoiding both excessive bloat and insufficient coverage.

Completeness4/5

The tool set provides strong coverage for security testing, including authentication (e.g., api_login, basic_auth, token_auth) and vulnerability checks (e.g., sql_injection_check, xss_check). Minor gaps might exist, such as lack of tools for specific advanced attacks or reporting features, but core workflows for authentication and basic security assessments are well-covered without dead ends.
