News, tutorials, and insights from the LocalStack team on cloud emulation, product showcases, and local development practices.https://blog.localstack.cloud/https://blog.localstack.cloud/test-snowflake-sql-locally-with-your-ai-agent/https://blog.localstack.cloud/test-snowflake-sql-locally-with-your-ai-agent/We gave Claude Code the LocalStack MCP server and a CSV export of SaaS billing data, then asked it to build a quarterly Revenue-by-Plan report on our Snowflake emulator. It loaded the data, found & fixed two bugs, and proved the result, without touching the real Snowflake cloud.Tue, 29 Sep 2026 00:00:00 GMThttps://blog.localstack.cloud/give-your-ai-agent-an-undo-button-for-aws-state/https://blog.localstack.cloud/give-your-ai-agent-an-undo-button-for-aws-state/We gave Claude Code the LocalStack MCP server and a real AWS CDK app, then made a one-line change that looked harmless, which then silently destroyed the data on deployment. The agent caught it, rolled back to a Cloud Pod, and we fixed it forward, all through the MCP server.Wed, 23 Sep 2026 00:00:00 GMThttps://blog.localstack.cloud/ask-your-ai-agent-to-break-your-cloud-app/https://blog.localstack.cloud/ask-your-ai-agent-to-break-your-cloud-app/We asked Claude Code to run a chaos game day against a serverless data pipeline on LocalStack: define a steady state, inject faults into every hop, diagnose the failures from App Inspector traces, fix the pipeline, and prove the fix by replaying the same faults.Mon, 14 Sep 2026 00:00:00 GMThttps://blog.localstack.cloud/stop-prompting-your-ai-agent/https://blog.localstack.cloud/stop-prompting-your-ai-agent/Stop writing bigger and bigger prompts for your AI coding agent. Learn how to build an AI-native AWS development environment using Cursor Rules, agent skills and plugins, the AWS MCP Server, and LocalStack so your agent has what it needs to build, test, and debug AWS applications locally before touching a real cloud account.Tue, 01 Sep 2026 00:00:00 GMThttps://blog.localstack.cloud/use-aws-mcp-servers-with-localstack/https://blog.localstack.cloud/use-aws-mcp-servers-with-localstack/AWS ships a fleet of official MCP servers that let agents write IaC, validate it, and invoke Lambda functions. Point them at LocalStack instead of real AWS, and an agent can build, harden, deploy, and test the cloud app locally. Here is how we wired them up and what happened.Tue, 18 Aug 2026 00:00:00 GMThttps://blog.localstack.cloud/give-your-coding-agent-a-real-cloud-to-break/https://blog.localstack.cloud/give-your-coding-agent-a-real-cloud-to-break/We gave Claude Code the LocalStack MCP server and a production bug report about a broken dead-letter queue, then watched it deploy, reproduce the failure from App Inspector traces, fix the pipeline, and prove the fix, without touching an AWS account.Tue, 11 Aug 2026 00:00:00 GMThttps://blog.localstack.cloud/localstack-for-ai-agents/https://blog.localstack.cloud/localstack-for-ai-agents/We launched a dedicated entry point that lets your AI agent discover, install, and start using LocalStack without you having to explain anything. Here's what's in it and why we built it.Tue, 09 Jun 2026 00:00:00 GMThttps://blog.localstack.cloud/introducing-localstack-mcp-server/https://blog.localstack.cloud/introducing-localstack-mcp-server/We're excited to introduce the LocalStack MCP Server, which enables AI agents to directly manage LocalStack through a standardized protocol, utilizing various tools. This allows agents to automate the entire local cloud development lifecycle via a conversational interface.Tue, 14 Oct 2025 00:00:00 GMT
