AWS Cost Explorer MCP

An MCP server that pulls live AWS spend by service, flags anomalies in real time, and suggests rightsizing actions per resource. Plugs the FinOps gap in the official AWS MCP, which is scoped to Bedrock Knowledge Bases.

🎯The Problem

AWS's official MCP is Knowledge Base only, and the dev.to top-15 MCP article called out FinOps as the obvious missing capability. Founders only discover the runaway $400/day NAT Gateway bill 11 days after it started, and figuring out which EC2 to rightsize means exporting CSVs from Cost Explorer and squinting at CloudWatch graphs for an hour.

💡The Solution

Wraps Cost Explorer, CloudWatch, and the Compute Optimizer APIs behind MCP tools. Pulls daily spend by service with deltas, runs anomaly detection on the time series, and returns rightsizing recommendations with projected monthly savings per resource.

👥Target Users

Indie devs and seed-to-Series-A startups running on AWS with $500-$20k/mo bills who have no dedicated FinOps person.

📊Difficulty: 6/10 — Intermediate

This is an intermediate micro-SaaS idea suited for builders with some shipping experience. Expect to work with third-party integrations, more complex data models, and nuanced user workflows that require careful planning.
