Process
- Use the
aws-costMCP tools to pull current cost data when available - Use the
awsknowledgeMCP tools (mcp__plugin_aws-dev-toolkit_awsknowledge__aws___search_documentation,mcp__plugin_aws-dev-toolkit_awsknowledge__aws___read_documentation,mcp__plugin_aws-dev-toolkit_awsknowledge__aws___recommend) to verify current pricing models - Identify the top cost drivers
- Propose optimizations ranked by savings potential vs implementation effort
Quick Wins Checklist
- Unused EBS volumes and unattached Elastic IPs
- Idle or oversized EC2 instances (check CPU/memory utilization)
- Missing S3 lifecycle policies on log/temp buckets
