Localstack MCP server — FAQ

Common questions about connecting and running Localstack.

  • What AWS services does LocalStack support?

    LocalStack emulates core AWS services including S3, DynamoDB, Lambda, SQS, SNS, and others. Check the LocalStack documentation for the full list of supported services and their feature parity with AWS.

  • Do I need a LocalStack Auth Token to use this MCP server?

    The LOCALSTACK_AUTH_TOKEN environment variable is optional and only required to unlock Pro features. Community features work without authentication.

  • How do I install and run the LocalStack MCP server?

    Install via npm with `npx @localstack/localstack-mcp-server@0.1.5`. The server runs over stdio transport and integrates with Claude or other MCP-compatible clients.

  • Can I use LocalStack for production testing or only local development?

    LocalStack is designed for local development and testing to avoid cloud costs and latency. For production-like testing, consider using AWS LocalStack Pro or actual AWS environments.

  • What's the difference between LocalStack Community and Pro?

    Community edition covers basic AWS service emulation. Pro features require a LOCALSTACK_AUTH_TOKEN and provide advanced capabilities like persistence, debugging tools, and priority support.
