Connects Claude to LocalStack so you can manage local AWS infrastructure without leaving your conversation. You get tools for S3 bucket operations, SQS/SNS messaging, DynamoDB CRUD, Lambda invocations with logs, EventBridge rules and event publishing, Kinesis streams, Secrets Manager, SSM Parameter Store, and SES email sending. Useful when you're bootstrapping dev environments, seeding test data, debugging event driven workflows, or iterating on Lambda functions locally. Everything runs against LocalStack's Docker container on localhost:4566 with fake credentials. The npm package works with npx so there's no install ceremony, and all AWS services stay contained in your local environment.
