LocalStack MCP Server

Let an AI agent manage and interact with LocalStack on your machine.

[!IMPORTANT] The LocalStack MCP server is currently available as an experimental public preview. For questions, issues or feedback, please utilize the LocalStack Community slack or submit a GitHub Issue

LocalStack emulates the cloud on your local machine so software teams and AI agents can validate security, quality, and reliability faster and more safely than the cloud allows. This Model Context Protocol (MCP) server lets any MCP client (Cursor, Claude, VS Code, and more) start LocalStack, deploy infrastructure, and debug your local cloud in natural language.

Quick start

Set up the server in your MCP client with the interactive wizard:

npx -y @localstack/localstack-mcp-server init

The wizard detects your installed clients, asks how you want to run the server, and writes the configuration for you. You need a LocalStack Auth Token; the wizard reads LOCALSTACK_AUTH_TOKEN from your environment or asks for it. For the full options, prerequisites, and manual setup, see Installation.

What you can ask your agent

Once the server is configured, talk to LocalStack through your agent in natural language:

• "Start LocalStack and deploy the Terraform project in ./infra, then tell me which resources came up."
• "My Lambda calls are failing. Read the LocalStack logs, find the permission errors, and generate an IAM policy that fixes them."
• "Inject 500ms of latency into DynamoDB and confirm my retry logic still works."
• "Search the LocalStack docs for how to enable S3 event notifications and summarize the steps."

How it works

The server connects MCP-compatible apps directly to your local LocalStack environment and its emulated AWS services, so your assistant can operate the stack securely without custom scripts or manual setup.

This server eliminates custom scripts and manual LocalStack management. Your agent can:

• Start, stop, restart, and monitor LocalStack for AWS container status with built-in auth.
• Deploy CDK, Terraform, and SAM projects with automatic configuration detection.
• Search LocalStack documentation for guides, API references, and configuration details.
• Parse logs, catch errors, and auto-generate IAM policies from violations.
• Inject chaos faults and network effects into LocalStack to test system resilience.
• Manage LocalStack state snapshots via Cloud Pods for development workflows.
• Export, import, inspect, and reset LocalStack state locally with Export & Import State file-based workflows.
• Install, remove, list, and discover LocalStack Extensions from the marketplace.
• Launch and manage Ephemeral Instances for remote LocalStack testing workflows.
• Replicate external AWS resources into LocalStack with AWS Replicator so IaC stacks can resolve shared dependencies locally.
• Inspect LocalStack application flows with [App Inspector](https://docs.localstack.cloud/aws/capabilities/web-app/app-
