This is your go-to when you need to understand where AWS money is going or set up proper monitoring. It bundles three MCP servers: AWS Pricing for pre-deployment cost estimation, Cost Explorer for analyzing historical spending patterns, and CloudWatch for metrics and alarms. The workflow is solid: estimate costs before you deploy, track actual spending after, then optimize based on the data. It also hooks into CloudTrail for auditing who changed what, and the Well-Architected Security Assessment tools. The best part is the emphasis on checking pricing first rather than getting surprised later. Works well for both the "why is my bill so high" investigations and the proactive "let's not make that mistake" planning.
