安装

选择你的客户端

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "security-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/eth0izzle/security-skills",
        "~/.claude/skills/security-skills"
      ],
      "_inferred": true
    }
  }
}

打开 Claude Desktop → Settings → Developer → Edit Config。保存后重启应用。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "security-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/eth0izzle/security-skills",
        "~/.claude/skills/security-skills"
      ],
      "_inferred": true
    }
  }
}

Cursor 使用与 Claude Desktop 相同的 mcpServers 格式。项目级配置优先于全局。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "security-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/eth0izzle/security-skills",
        "~/.claude/skills/security-skills"
      ],
      "_inferred": true
    }
  }
}

点击 Cline 侧栏中的 MCP Servers 图标，然后选 "Edit Configuration"。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "security-skill": {
      "command": "git",
      "args": [
        "clone",
        "https://github.com/eth0izzle/security-skills",
        "~/.claude/skills/security-skills"
      ],
      "_inferred": true
    }
  }
}

格式与 Claude Desktop 相同。重启 Windsurf 生效。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "security-skill",
      "command": "git",
      "args": [
        "clone",
        "https://github.com/eth0izzle/security-skills",
        "~/.claude/skills/security-skills"
      ]
    }
  ]
}

Continue 使用服务器对象数组，而非映射。

~/.config/zed/settings.json

{
  "context_servers": {
    "security-skill": {
      "command": {
        "path": "git",
        "args": [
          "clone",
          "https://github.com/eth0izzle/security-skills",
          "~/.claude/skills/security-skills"
        ]
      }
    }
  }
}

加入 context_servers。Zed 保存后热重载。

claude mcp add security-skill -- git clone https://github.com/eth0izzle/security-skills ~/.claude/skills/security-skills

一行命令搞定。用 claude mcp list 验证，claude mcp remove 卸载。

使用场景

实战用法： security-skills

Produce a STRIDE threat model for a new feature

👤 Security engineers, staff+ engineers owning a feature's security review ⏱ ~45 min advanced

何时使用： Design review for a feature that touches user data, auth, or external networks.

前置条件

Feature design doc or architecture diagram — Paste into chat or point Claude at the file
Skill installed — git clone https://github.com/eth0izzle/security-skills ~/.claude/skills/security-skills

步骤

Walk the system

Use security-skills. Here's the design for [feature]. Enumerate trust boundaries and data flows.✓ 已复制

→ Named trust boundaries, explicit data flow arrows
Apply STRIDE

For each boundary, call out Spoofing, Tampering, Repudiation, Info Disclosure, DoS, Elevation risks.✓ 已复制

→ Table with threats scored, not generic 'consider XSS'
Propose mitigations

Rank the threats by likelihood * impact and propose concrete mitigations for the top 5.✓ 已复制

→ Specific controls (rate limit, signed requests, audit log)

结果： A threat model doc ready for a security review meeting.

注意事项

STRIDE becomes checkbox theater — Demand concrete attacker stories — 'attacker with X wants Y, does Z'

搭配使用： filesystem

Sweep a repo's dependencies for known CVEs

👤 Dev teams responding to a security advisory ⏱ ~30 min intermediate

何时使用： A new CVE drops and you need to know where you're exposed.

步骤

Point at the manifest

Use security-skills. Audit package-lock.json for dependencies with known CVEs published in the last 90 days.✓ 已复制

→ List of packages, advisory IDs, severity
Triage by usage

For each vulnerable dep, grep the codebase — is it actually reachable?✓ 已复制

→ Reachable vs unreachable classification
Draft an upgrade plan

Plan the minimum-risk upgrade order so CI doesn't explode.✓ 已复制

→ Ordered upgrade sequence with version pins

结果： A concrete patch plan — not 'run npm audit fix' and pray.

注意事项

Transitive dependencies missed — Use full lockfile, not just top-level manifest

搭配使用： filesystem · github

Review Terraform and k8s manifests for common misconfigs

👤 Platform engineers, DevSecOps ⏱ ~30 min intermediate

何时使用： Before merging IaC changes into main, or auditing what's already there.

步骤

Point Claude at the IaC directory

Use security-skills. Scan terraform/ for S3 buckets without encryption, IAM wildcards, public security groups.✓ 已复制

→ File+line references with severity
Get fixes

For each finding, propose the minimal Terraform diff to fix it.✓ 已复制

→ HCL snippets showing before/after

结果： PR-sized security fixes you can merge incrementally.

注意事项

False positives on intentional public assets — Tag resources that are intentionally public; the skill should skip them

搭配使用： github · filesystem

组合

与其他 MCP 搭配，撬动十倍杠杆

security-skill + github

Post findings as PR comments automatically

Review this PR and leave line comments for each security finding.✓ 已复制

security-skill + filesystem

Recursive scans across a monorepo

Walk the entire services/ tree and aggregate findings by service.✓ 已复制

工具

此 MCP 暴露的能力

工具	输入参数	何时调用	成本
threat_model	system description	Design-phase review	0
cve_audit	lockfile path	After a public CVE drops	0 (uses public advisory data)
iac_review	directory path	Pre-merge IaC audits	0
secret_scan	path or diff	Pre-commit or pre-push	0

成本与限制

运行它的成本

API 配额: None built-in
每次调用 Token 数: Moderate — depends on files inspected
费用: Free
提示: Scope scans to specific directories; don't point at node_modules.

安全

权限、密钥、影响范围

凭据存储： None in skill itself

数据出站： None — skill is prompts; be aware inspected code goes to Claude API

Defensive only. Do not use for exploitation, credential harvesting, or red-team operations.
Never paste production secrets into prompts — even when asking the skill to 'find them'.

故障排查

常见错误与修复

Skill suggests exploitation techniques

Re-prompt for defensive framing: 'as a defender, how do I prevent X'

Too many false positives on IaC scan

Provide context (prod vs staging; intentional public resources)

Missed a known vulnerability

Claude's knowledge cutoff may lag. Pair with a proper scanner (Trivy, Snyk) for authoritative CVE data.

替代方案

security-skills 对比其他方案

替代方案	何时用它替代	权衡
Trivy / Grype	You need an authoritative, up-to-date vulnerability database	No LLM reasoning — just raw scan output
tfsec / checkov	Specific IaC scanning with a curated rule set	Rule-bound; misses nuanced misconfigs
