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

VS Code → Cline → MCP Servers → Edit

Clique no ícone MCP Servers na barra lateral do Cline, depois "Edit Configuration".

Casos de uso

Usos do mundo real: claude-skills

Get an architecture review before you commit to a stack

👤 Tech leads starting a new service ⏱ ~30 min intermediate

Quando usar: You're about to pick a framework and database for a new product and want a sanity check.

Fluxo

Describe the service

Use the engineering skills. We need a real-time collab API — 10k concurrent users, document sync, presence. Compare Node+WebSocket vs Elixir+Phoenix vs Go+gRPC.✓ Copiado

→ Comparison grounded in real tradeoffs from the respective skills
Probe risks

For the choice you'd recommend, what fails at 100k users?✓ Copiado

→ Concrete scaling cliffs, not generic platitudes

Resultado: A decision doc with tradeoffs and scaling risks identified.

Armadilhas

Skill over-recommends the framework it has the deepest skill for — Ask it to explicitly state why NOT each option

Run an incident response playbook for a production outage

👤 On-call engineers during a live incident ⏱ ~15 min advanced

Quando usar: Production is on fire and you need structured triage without panicking.

Fluxo

Open the incident

Use the incident-response skill. Symptoms: API 500s spiking in US-east, started 10 min ago.✓ Copiado

→ Claude walks through structured diagnosis — triage tree, log queries, mitigation options
Follow-up postmortem

Now draft the postmortem template using what we learned.✓ Copiado

→ Filled-in template with blameless framing

Resultado: Faster time-to-mitigate and a credible postmortem.

Armadilhas

Skill suggests generic mitigations without knowing your stack — Tell it your stack upfront — 'we're on AWS ECS + RDS Postgres'

Combine com: aws · sentry

Use the CTO skill to pressure-test a board deck

👤 Founders and CTOs prepping for fundraising ⏱ ~45 min advanced

Quando usar: You have the tech section of a deck and want senior-CTO red team feedback.

Fluxo

Share the slides

Use the CTO advisory skill. Here's our tech architecture slide — what would a skeptical board member ask?✓ Copiado

→ Specific, pointed questions tied to slide content
Prep answers

For each question, draft a crisp answer with data we'd need to back it up.✓ Copiado

→ Prep notes you can actually rehearse

Resultado: A rehearsed Q&A for the tech portion of your board meeting.

Armadilhas

Questions feel generic — Feed in your actual architecture docs, not just the deck summary

Combinações

Combine com outros MCPs para 10× de alavancagem

claude-skill + github

Engineering skills suggest the change; GitHub MCP opens the PR

Use the backend skill to design the refactor, then open a PR in our repo with the plan as the description.✓ Copiado

claude-skill + filesystem

Skills produce docs; filesystem stores them in the repo

Save the architecture review output to docs/architecture/ and create a README index.✓ Copiado

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar
Engineering skills	technical question or design brief	Backend, frontend, DevOps, security work
Marketing skills	campaign or content brief	Content, SEO, CRO, growth work
C-Level advisory skills	strategic question	Board, fundraising, executive hiring
POWERFUL Tier skills	complex scenario (RAG, DB, incident)	When a basic skill isn't enough
Regulatory/quality skills	compliance question	Regulated industries

Custo e limites

O que custa rodar

Cota de API: None
Tokens por chamada: Varies wildly by skill; big skills load 5-15k tokens of references
Monetário: Free — skills are local
Dica: The library is too big to let Claude browse freely. Name the skill or domain in the prompt.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: No credentials — skill is prompts

Saída de dados: None from the skill itself

C-level and regulatory skills still need human review — don't ship compliance decisions on skill output alone.

Solução de problemas

Erros comuns e correções

Claude picks the wrong skill for a task

Reference by domain: 'use the marketing > SEO skill'. With 235+ skills, auto-routing is fuzzy.

SKILL.md loads are too large

Pin to one skill at a time; don't try to load multiple domains in one prompt.

Python CLI helpers not found

Some skills require optional Python utils — check the skill's setup section.

Alternativas

claude-skills vs. outros

Alternativa	Quando usar	Troca
claude-skill-2 (Jeffallan)	You only want full-stack dev (66 skills), not marketing/compliance	Narrower, less overwhelming
awesome-claude-skill	You want to browse skills, not install a mega-bundle	Directory vs installable pack
Single-purpose skills (terraform, playwright, tutor)	You have one specific problem	Sharper focus
