Cursor usa el mismo esquema mcpServers que Claude Desktop. La configuración del proyecto prevalece sobre la global.

Casos de uso

Usos del 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

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

Flujo

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.

Errores comunes

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

Combinar con: terraform-skill

Design an EventBridge → Step Functions → Lambda pipeline

👤 Serverless engineers ⏱ ~40 min advanced

Cuándo usarlo: You need an event-driven workflow and want the right service boundaries.

Flujo

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.

Errores comunes

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

Combinar con: terraform-skill

Scaffold a Bedrock-backed RAG service

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

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

Flujo

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.

Errores comunes

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

Combinaciones

Combínalo con otros MCPs para multiplicar por 10

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

Herramientas

Lo que expone este MCP

Herramienta	Entradas	Cuándo llamar
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

Coste y límites

Lo que cuesta ejecutarlo

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

Seguridad

Permisos, secretos, alcance

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

Salida de datos: None from the skill itself

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

Resolución de problemas

Errores comunes y soluciones

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 otros

Alternativa	Cuándo usarla	Contrapartida
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
