  "summary": "LocalStack is automatable today through its CLI. This record is the local cloud emulator, including LocalStack for AWS. It is not Amazon Web Services, and it is not the unrelated io.github.giovanemartins/localstack listing. An auth token is required to start the LocalStack for AWS image and to activate licensed features. localstack auth set-token stores the token, and localstack start runs the emulator. LOCALSTACK_AUTH_TOKEN is the environment variable for the CLI, Docker, and Docker Compose. The lstk CLI can start a browser OAuth flow instead. Activation status is GET http://localhost:4566/_localstack/info, which returns JSON including edition and is_license_activated. The homepage documents a Hobby plan with free non-commercial access to basic emulation of 30 AWS services, and paid Base, Ultimate, and Enterprise plans. LocalStack is for development and testing, not production. LocalStack publishes github.com/localstack/localstack-mcp-server as an experimental public preview. Every tool requires LOCALSTACK_AUTH_TOKEN. Tools start the emulator, deploy CDK, Terraform, or SAM, read logs, and inject faults. The emulated AWS service APIs were not opened as a separate LocalStack management API, so the API score stays unset. Connector catalogs were not opened. Computer-use viability is unassessed. The CLI scores 7 and is the best path. The experimental MCP server scores 5.\n"
