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

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

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

Casos de uso

Usos do mundo real: terrashark

How to scaffold a production-grade AWS VPC module

👤 Platform engineers starting a new environment ⏱ ~45 min intermediate

Quando usar: Day one of a new AWS account; you want a VPC module that won't embarrass you in 6 months.

Pré-requisitos

Skill installed — git clone https://github.com/LukasNiessen/terrashark ~/.claude/skills/terrashark
terraform CLI 1.6+ — brew install terraform

Fluxo

Generate module

Use terrashark. AWS VPC module, 3 AZs, public + private + db subnets, NAT gateways per AZ, flow logs on.✓ Copiado

→ Module with variables.tf, main.tf, outputs.tf — no hallucinated args
Add security defaults

Ensure default security group denies all, flow logs go to CloudWatch with KMS-CMK encryption.✓ Copiado

→ Security group + logging + KMS wired
Validate

Run terraform init + validate + plan with example tfvars.✓ Copiado

→ Clean plan output, no errors

Resultado: A VPC module that terraform validates clean and follows AWS best practices.

Armadilhas

LLM suggests deprecated aws_vpc_endpoint arg — TerraShark grounds in current docs; if drift still happens, ask it to cite the HashiCorp page
Module too monolithic — Ask for split: networking module vs. endpoints module separately

Combine com: aws-skill

Fix LLM-generated Terraform that doesn't plan

👤 Engineers cleaning up AI-generated IaC ⏱ ~20 min intermediate

Quando usar: Another LLM gave you Terraform that looks reasonable but terraform plan fails on unknown arguments.

Fluxo

Point at the broken file

terraform plan fails on modules/rds. Use terrashark to fix each invalid argument with the current correct form.✓ Copiado

→ Per-error fix with HashiCorp doc reference
Validate

Re-run plan; if any errors remain, iterate.✓ Copiado

→ Clean plan

Resultado: A file that plans clean.

Design a remote state layout for multi-env

👤 Teams graduating from local state ⏱ ~60 min advanced

Quando usar: You have dev + staging + prod and one giant terraform.tfstate.

Fluxo

Propose layout

Design S3 remote backend with per-env state files and DynamoDB locking. 3 envs.✓ Copiado

→ Backend config per env with key separation + locking
Migration plan

Plan the migration from a single local state to this layout, step by step.✓ Copiado

→ terraform state mv steps + safety checkpoints

Resultado: A state layout you can migrate to without losing state.

Armadilhas

Accidentally deleting state during migration — Always pull and back up state files before any mv operation

terrashark-skill + aws-skill

AWS skill sizes architecture, TerraShark implements IaC

Design the architecture with aws-skill, implement as Terraform with terrashark.✓ Copiado

terrashark-skill + claude-code-owasp-skill

Security-review the generated IaC

After terrashark scaffolds the module, run OWASP security review on the IAM and networking blocks.✓ Copiado

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar	Custo
Module scaffolding	provider, resource shape	Greenfield IaC	Claude tokens
Hallucination fix	tf file + error log	Cleaning up AI-generated TF	Claude tokens
State layout design	envs, team shape	Multi-env setups	Claude tokens
Security defaults	-	Pre-prod review	Claude tokens

Custo e limites

O que custa rodar

Cota de API: None
Tokens por chamada: 10-30k per module
Monetário: Free
Dica: Generate module by module, not whole environment in one shot.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: No credentials. TerraShark doesn't run terraform apply itself.

Saída de dados: Prompts go to Claude. Terraform plan/apply hits your cloud provider using your local creds.

Always review generated IAM policies before apply. LLMs can silently over-grant.

Solução de problemas

Erros comuns e correções

terraform validate fails on unknown argument

Ask TerraShark to reconcile against the current provider doc URL; provider version may be newer than the skill's prompt context.

Verificar: terraform providers

Plan creates unwanted destroys

Usually state-drift or implicit renaming. Run terraform plan -target to isolate before apply.
