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

Casos de uso

Usos do mundo real: cti-expert

How to enrich a suspicious indicator (IP, domain, hash) with public OSINT

👤 SOC analysts, incident responders, blue-team engineers ⏱ ~15 min intermediate

Quando usar: You have an IOC from an alert and need context before escalating.

Pré-requisitos

Skill cloned — git clone https://github.com/7onez/cti-expert ~/.claude/skills/cti-expert

Fluxo

Submit the indicator

Enrich 185.234.218.95 using public OSINT — WHOIS, passive DNS (free sources), reputation feeds.✓ Copiado

→ Structured context: ASN, geo, historical resolutions, known bad
Map to MITRE ATT&CK if applicable

If this matches a known campaign, map to ATT&CK tactics/techniques.✓ Copiado

→ TTP list with ATT&CK IDs
Write up

Produce a tactical report: what it is, confidence level, recommended actions.✓ Copiado

→ Short, decision-oriented write-up

Resultado: A defensible enrichment you can attach to a ticket in minutes.

Armadilhas

Treating reputation scores as ground truth — Record the source + date; note confidence explicitly
OSINT queries accidentally tip off the target — Only use passive sources; no active scanning

Combine com: filesystem

Draft a campaign write-up from a handful of artifacts

👤 CTI analysts producing internal reports ⏱ ~45 min advanced

Quando usar: You've been asked to turn a pile of IOCs, TTPs, and notes into a readable brief.

Fluxo

Collate the artifacts

Here are the IOCs and notes. Cluster them by diamond-model facet (adversary, capability, infra, victim).✓ Copiado

→ Diamond-model-shaped clustering
Map to ATT&CK

Map observed behaviors to ATT&CK; note coverage gaps.✓ Copiado

→ Coverage matrix
Write the brief

Produce an executive section, a tactical section, and an IOC appendix.✓ Copiado

→ 3-part report

Resultado: A consistent, audience-tiered report ready for review.

Armadilhas

Inflating confidence language ('almost certainly') — Force IC-style qualifiers (high/moderate/low) with reasoning

Run an ACH (Analysis of Competing Hypotheses) walk-through

👤 Analysts wrestling with ambiguous attribution ⏱ ~30 min advanced

Quando usar: Multiple actors could explain the evidence; you want structure before picking one.

Fluxo

List hypotheses + evidence

Hypotheses: H1, H2, H3. Evidence: E1–E10. Set up the ACH matrix.✓ Copiado

→ Matrix with consistency marks per cell
Identify diagnostic evidence

Which evidence items have the highest diagnostic value?✓ Copiado

→ Evidence ranked by ability to discriminate
Report the least-inconsistent hypothesis

Pick the least-inconsistent hypothesis and list what would flip it.✓ Copiado

→ Selection + counter-evidence triggers

Resultado: A transparent attribution decision with documented reasoning.

Armadilhas

Anchoring on the first hypothesis — Force the matrix first, conclusion last

Combinações

Combine com outros MCPs para 10× de alavancagem

cti-expert-skill + filesystem

Process a directory of raw alerts into structured findings

Enrich every IOC under alerts/2025-04-01/ and produce a consolidated daily tactical report.✓ Copiado

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar	Custo
indicator-enrichment	IOC (IP/domain/hash/URL)	Triage of any incoming indicator	free OSINT queries
attck-mapping	observed behaviors	When writing up campaigns or detections	0
structured-analytic-techniques	hypotheses + evidence	Ambiguous analysis problems	0
report-templates	findings	Final reporting step	0

Custo e limites

O que custa rodar

Cota de API: depends on the OSINT sources used; all default sources are free-tier
Tokens por chamada: 2–10k tokens per indicator workflow
Monetário: free
Dica: Start with passive sources only; add paid feeds only if coverage gaps justify it

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: none by default; any paid feed API key lives in env vars

Saída de dados: only the OSINT endpoints you allow-list

Strictly defensive use — do not use enrichment output to target individuals or organizations
OSINT queries may be logged by target infrastructure; prefer passive sources
Respect legal frameworks (GDPR, data protection) when handling IOCs tied to persons

Solução de problemas

Erros comuns e correções

Rate limited by a public source

Throttle or switch to an alternate source — many OSINT endpoints are sensitive

Claude hallucinates an enrichment result

Require citations for every claim; reject unsourced enrichment

ATT&CK mapping is too generic

Provide concrete behaviors (processes, commands, network patterns), not high-level summaries

Alternativas

cti-expert vs. outros

Alternativa	Quando usar	Troca
claude-cybersecurity-skill	You want broader security skills, not just CTI	Wider but shallower in CTI specifics
claude-security-research-skill	You're researching vulnerabilities rather than triaging indicators	Different job entirely
