AWS Infrastructure as Code

AWS Infrastructure as Code

Key Tools

• search_cdk_documentation / search_cdk_samples_and_constructs - CDK docs and code samples
• cdk_best_practices - Comprehensive CDK best practices
• read_iac_documentation_page - Full documentation pages
• validate_cloudformation_template - cfn-lint validation
• check_cloudformation_template_compliance - cfn-guard security compliance
• troubleshoot_cloudformation_deployment - Pattern-based failure analysis with CloudTrail
• search_cloudformation_documentation - CloudFormation docs

CDK Development Workflow

1. Research: search_cdk_documentation + search_cdk_samples_and_constructs
2. Best Practices: cdk_best_practices
3. Write CDK Code
4. Synthesize: cdk synth
5. Validate: validate_cloudformation_template + check_cloudformation_template_compliance
6. Deploy: cdk deploy
7. Troubleshoot: troubleshoot_cloudformation_deployment (if needed)

Best Practices

• Prefer L2 constructs, use L3 for patterns, avoid L1 unless necessary
• Search before coding to find proven patterns
• Always synthesize (cdk synth) to validate before deployment
• Check compliance before production
• Supports TypeScript, Python, Java, C#, Go

MCP Server Config

{
  "mcpServers": {
    "aws-iac": {
      "command": "uvx",
      "args": ["awslabs.aws-iac-mcp-server@latest"],
      "env": {
        "AWS_PROFILE": "default",
        "AWS_REGION": "us-east-1",
        "FASTMCP_LOG_LEVEL": "ERROR"
      }
    }
  }
}

Most features work without AWS credentials. Credentials only needed for deployment and troubleshooting.
