Abra Claude Desktop → Settings → Developer → Edit Config. Reinicie após salvar.

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".

Casos de uso

Usos do mundo real: aws-agent-skills

Write a least-privilege IAM policy for a Lambda + DynamoDB pair

👤 Backend engineers setting up AWS resources ⏱ ~15 min intermediate

Quando usar: You're wiring a Lambda to a Dynamo table and don't want to give it * permissions.

Fluxo

State the access needed

Use the aws iam + lambda skills. Write a policy for a Lambda that needs GetItem and UpdateItem on table Orders and nothing else.✓ Copiado

→ Policy with exact actions + resource ARN, no wildcards
Test

Give me the aws iam simulate-custom-policy command to verify this allows only those two actions.✓ Copiado

→ Runnable command with correct syntax

Resultado: A production-quality least-privilege IAM policy with verification.

Armadilhas

Policy uses wildcards for convenience — Insist on exact resource ARNs — skill supports this strongly

Combine com: terraform-skill

Design an EventBridge → Step Functions → Lambda pipeline

👤 Serverless engineers ⏱ ~40 min advanced

Quando usar: You need an event-driven workflow and want the right service boundaries.

Fluxo

Sketch the flow

Use the eventbridge + step-functions + lambda skills. Design a pipeline that triggers on S3 uploads, orchestrates 3 steps, and writes to DynamoDB.✓ Copiado

→ Architecture diagram + IaC snippets
Observability

Now add CloudWatch alarms and structured logging.✓ Copiado

→ Specific metric filters and alarm thresholds

Resultado: A buildable serverless architecture with monitoring.

Armadilhas

Step Functions costs explode at scale — Skill flags when Express workflows fit better than Standard

Combine com: terraform-skill

Scaffold a Bedrock-backed RAG service

👤 Engineers building LLM features on AWS ⏱ ~60 min advanced

Quando usar: You want to use Bedrock for embeddings + generation without piecing it together from blog posts.

Fluxo

Describe the service

Use the bedrock + s3 + dynamodb skills. Scaffold a RAG service: upload docs to S3, embed with Titan, store in DynamoDB, retrieve + generate at query time.✓ Copiado

→ Runnable code with correct Bedrock invoke calls and embedding model IDs

Resultado: A first-pass RAG scaffold on AWS-native services.

Armadilhas

Using Dynamo for vector search at scale — Skill notes when OpenSearch or pgvector is a better fit

Combinações

Combine com outros MCPs para 10× de alavancagem

aws-agent-skill + terraform-skill

AWS skills propose the design; Terraform skill writes the HCL

Design the Lambda+Dynamo stack using the aws skills, then have terraform-skill write the module.✓ Copiado

aws-agent-skill + aws

Skill tells Claude the right calls; AWS MCP actually runs them

Use the aws-agent-skills to design the policy, then apply it via the aws MCP.✓ Copiado

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar
IAM skill	role/policy intent	Any AWS permissions work
Lambda skill	function spec	Serverless function design
DynamoDB skill	access patterns	NoSQL modeling
CloudFormation skill	resources	IaC in CFN
Bedrock skill	LLM use case	Using AWS-native GenAI

Custo e limites

O que custa rodar

Cota de API: None for the skill
Tokens por chamada: 3-8k per service loaded
Monetário: Free — skill is local. AWS usage costs are yours.
Dica: Name the services you're using so Claude loads only those SKILL.md files.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: No credentials in the skill. Real AWS calls should use OIDC roles, not static keys.

Saída de dados: None from the skill itself

Double-check generated IAM policies before deploying — the skill aims for least-privilege but you know your workload best.

Solução de problemas

Erros comuns e correções

CLI flag rejected by actual AWS CLI

AWS occasionally renames flags. Check the service's last-updated metadata; cross-reference official docs if stale.

Verificar: aws <service> <command> help

Claude uses SDK v2 patterns for Python boto3

Boto3 is v1 (and stable); don't confuse with AWS SDK for JS v2/v3. Specify language explicitly.

Alternativas

aws-agent-skills vs. outros

Alternativa	Quando usar	Troca
aws MCP	You want Claude to actually call AWS, not just write snippets	MCP executes; this skill informs
cloud-provider-agnostic IaC skills (pulumi, cdk)	You prefer code-first IaC	Different mental model
