Cursor usa o mesmo esquema mcpServers que o Claude Desktop. Config de projeto vence a global.

Casos de uso

Usos do mundo real: claude-code-owasp

How to security-review a PR with OWASP Top 10 in mind

👤 Developers doing self-review before requesting human review ⏱ ~20 min intermediate

Quando usar: Before you click 'Ready for review' on a PR that touches auth, data, or input handling.

Pré-requisitos

Skill installed — git clone https://github.com/agamm/claude-code-owasp ~/.claude/skills/claude-code-owasp

Fluxo

Point at the diff

Review the current PR against OWASP Top 10:2025. Focus on auth and input handling.✓ Copiado

→ Findings mapped to Top 10 categories with line references
Prioritize

Group findings into 'must-fix before merge' vs 'follow-up issue'. Cite the specific ASVS requirement.✓ Copiado

→ Ranked list with ASVS IDs
Generate fixes

For each must-fix, propose the minimal diff.✓ Copiado

→ Patch diffs keyed to findings

Resultado: A PR that ships with known security issues resolved, with traceable requirements.

Armadilhas

Over-alerting on benign patterns — Ask Claude to show the exploit path concretely; if it can't, downgrade the severity

Run a lightweight threat model on a new feature

👤 Engineers designing a feature involving user data ⏱ ~40 min advanced

Quando usar: Design stage, before writing the code, when the blast radius is still negotiable.

Fluxo

Describe the feature

Feature: share-by-link for customer reports. Users generate tokenized URLs valid 7 days. Threat-model with OWASP agentic AI guidance included.✓ Copiado

→ STRIDE-style list of threats
Pick controls

For each threat, what's the cheapest control that mitigates 80%?✓ Copiado

→ Per-threat control + rejection rationale for expensive ones

Resultado: A threat model document you can attach to the design doc.

Armadilhas

Over-engineered control list — Explicitly limit to top-5 threats by likelihood × impact

Harden an AI agent integration against prompt injection

👤 Engineers shipping Claude/LLM-powered features ⏱ ~30 min advanced

Quando usar: You're about to let an LLM touch user data or call tools.

Fluxo

Describe the agent surface

Our agent reads support emails and can call 3 tools: refund(), tag_account(), escalate(). Review for agentic AI risks.✓ Copiado

→ Prompt-injection vectors, tool-misuse risks, data exfil paths
Design guardrails

Propose a minimal guardrail set: which tools need human confirm, which inputs need sanitization, what logging is required.✓ Copiado

→ Concrete guardrail spec

Resultado: A hardened agent design with documented guardrails.

Armadilhas

Relying on prompt-based defenses alone — Combine with deterministic controls — human-in-loop for destructive tools, allowlists for URLs

Audit for language-specific security quirks

👤 Reviewers checking a codebase in a language they don't know deeply ⏱ ~15 min intermediate

Quando usar: You're reviewing Python code as a TS native, or vice versa.

Fluxo

Scope to language

Review this Python module for Python-specific OWASP quirks (pickle, yaml.load, shell=True, etc.).✓ Copiado

→ Language-specific findings beyond generic Top 10

Resultado: Catches that a language-agnostic review would miss.

Overlap on security headers

Run seo-audit security category, then deeper OWASP review on the hits.✓ Copiado

Secure ROS networking (rosbridge, Zenoh)

Robotics skill produced a rosbridge websocket — run OWASP review on it.✓ Copiado

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar	Custo
Top 10:2025 review	diff or files	PR self-review	Claude tokens
ASVS requirement check	feature spec	Compliance work	Claude tokens
Agentic AI threat model	agent design	Shipping LLM features	Claude tokens
Language-specific audit	language, files	Cross-language review	Claude tokens

Custo e limites

O que custa rodar

Cota de API: None
Tokens por chamada: 5-20k per review depending on code size
Monetário: Free
Dica: Scope reviews to changed files, not the whole repo.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: No credentials

Saída de dados: Code is sent to Claude for inference

Not a replacement for human security review on anything material. Treat as a force multiplier.

Solução de problemas

Erros comuns e correções

Claude ignores OWASP context and gives generic advice

Explicitly name the guidance: 'Apply OWASP Top 10:2025 category A03:2025 Injection here.'

Too many false positives

Require an exploit walkthrough before accepting a finding
