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

O Continue usa um array de objetos de servidor em vez de um map.

Casos de uso

Usos do mundo real: terraform-skill

Scaffold a new Terraform module the idiomatic way

👤 Platform engineers publishing a reusable module ⏱ ~45 min intermediate

Quando usar: You're splitting out a module for internal or public reuse and want the structure right the first time.

Fluxo

State the module's purpose

Use the terraform-skill. Scaffold a module for an AWS ECS service with optional ALB and CloudWatch alarms.✓ Copiado

→ Structure follows terraform-aws-modules conventions — main.tf, variables.tf, outputs.tf, versions.tf, README.md, examples/
Add tests

Recommend tests — native or Terratest? Apply the decision framework.✓ Copiado

→ Reasoned choice and scaffolded test files

Resultado: A module that passes review on the first PR.

Armadilhas

Versioning too loose (~> vs specific) — Skill defaults to pinned minors for required_providers

Combine com: github

Add a hardened CI pipeline to an existing Terraform repo

👤 DevOps / platform engineers ⏱ ~40 min advanced

Quando usar: Your repo lacks plan-on-PR, cost checks, or security scans.

Pré-requisitos

GitHub or GitLab hosting — For the respective pipeline template

Fluxo

Request the pipeline

Use terraform-skill. Add GitHub Actions for plan-on-PR, Infracost, tfsec, and gated apply on main.✓ Copiado

→ Workflow files with concurrency guards, OIDC auth, status checks
Security tune

Which Checkov / tfsec rules should we fail on vs warn?✓ Copiado

→ Opinionated list with rationale

Resultado: A pipeline that blocks risky changes without slowing everyone down.

Armadilhas

Pipeline uses long-lived AWS keys — Skill prefers OIDC/role assumption, not static keys

Combine com: github

Design a multi-environment layout without state explosions

👤 Teams scaling from dev/prod to dev/staging/prod/per-tenant ⏱ ~60 min advanced

Quando usar: You feel the pain of copy-pasted env folders or a monolith state.

Fluxo

Describe the envs

Use terraform-skill. We need dev/staging/prod plus per-tenant envs. What layout scales?✓ Copiado

→ Recommendation with tradeoffs (workspaces vs dirs vs Terragrunt)
Plan the migration

We're currently on a single state. Sketch the migration.✓ Copiado

→ State-move plan with risk callouts

Resultado: A layout you can defend in an ADR.

Armadilhas

Moving state without imports/breakdowns can destroy resources — The skill insists on terraform state mv / import steps, not delete-and-recreate

Combinações

Combine com outros MCPs para 10× de alavancagem

terraform-skill + github

Skill produces module + workflow; GitHub MCP opens the PR

Scaffold the module, add the workflow, open a PR into our platform repo.✓ Copiado

terraform-skill + aws

Cross-check the Terraform plan against live AWS state

Show me the plan, then diff against actual resources via the AWS MCP.✓ Copiado

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar
Module scaffolding	module purpose + provider	Starting a new module
Test strategy advisor	module scope	Adding test coverage
CI pipeline templates (GHA / GitLab)	hosting choice	Setting up CI for a repo
Pattern compare	a snippet	Reviewing existing code

Custo e limites

O que custa rodar

Cota de API: None
Tokens por chamada: 2-6k per session — moderate
Monetário: Free — skill is local
Dica: Ask one focused question (testing / CI / layout) at a time.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: No credentials in the skill. Any provider creds belong in your env, not the generated code.

Saída de dados: None from the skill itself

Generated CI pipelines may reference secret names — make sure you set those secrets in the repo settings before merging.

Solução de problemas

Erros comuns e correções

Skill's suggestion conflicts with your org's style

Provide your .terraform-docs config and existing module as style anchors.

Recommended OIDC setup fails on assume-role

Check the trust policy's sub condition matches your branch/env.

Alternativas

terraform-skill vs. outros

Alternativa	Quando usar	Troca
Terragrunt-first skills	You're committed to Terragrunt	Less coverage here; Terragrunt workflows differ substantially
Cloud-provider-native IaC skills (aws-cdk, pulumi)	You're not on Terraform/OpenTofu	Different tool, different patterns
