At FinOps X this week, AWS announced the public preview of AWS FinOps Agent. It investigates cost anomalies by correlating spend changes with CloudTrail events, identifies what changed and who changed it, and delivers the findings in Slack and Jira. It draws on Cost Explorer, Cost Anomaly Detection, Cost Optimization Hub, and Compute Optimizer.

This is good for AWS customers. Anomaly investigation was painful. Someone gets a Cost Anomaly Detection alert, then spends hours digging through CloudTrail logs and Cost Explorer to figure out what happened. AWS FinOps Agent automates that. Free (during preview), native, no integration required. Every AWS customer should turn it on.

But it’s worth understanding what it is and what it isn’t.

What AWS FinOps Agent Does

AWS FinOps Agent is an investigation tool. Something changed in your bill. The agent figures out what and tells you about it. It answers cost questions. It surfaces anomaly root causes.

This is reactive. Something already happened. The agent tells you what it was. That’s valuable. It’s also about 10% of the job.

What It Doesn’t Do

It doesn’t find the 20-35% of your AWS spend that’s wasted on misconfigured resources. It doesn’t tell you which GP2 volumes should be GP3. It doesn’t find idle RDS instances or unattached EBS volumes or S3 buckets with no lifecycle policies. It doesn’t validate recommendations against your actual utilization data or attach dollar amounts to each finding.

The agent draws on Cost Optimization Hub and Compute Optimizer. Those are AWS’s own recommendation engines. They cover the basics: rightsizing, idle resources, some commitment suggestions. They’re broad but not deep. AWS has hundreds of services. Cost Optimization Hub covers a fraction of them.

What Third-Party Agents Are Doing

Vantage launched a FinOps Agent that lets you ask questions about your bill in natural language and auto-purchases Savings Plans (with a 5% fee on every commitment). ProsperOps has autonomous discount management. DoiT has PerfectScale for Commitments.

These are all layers on top of the same AWS cost data. Now that AWS gives you an agent for free, the question for third-party tools is: what do you add that AWS doesn’t already give away?

For most of them, the answer is “a better interface on the same data.” That’s not nothing. But it’s also not a moat.

What CloudFix Does Differently

CloudFix doesn’t give you another lens on your bill. It gives you a pre-analyzed, pre-validated fix list.

Over 100 finders continuously scan your AWS infrastructure. Each recommendation comes with a validation chain: the metrics, the thresholds, the pass/fail results, the exact dollar savings. Your agent doesn’t need to figure out what’s wrong. It queries the answer.

CloudFix ships an MCP server so any AI agent (Claude, ChatGPT, Cursor, Windsurf, or the new AWS FinOps Agent itself) can query validated recommendations directly. No integration code. No middleware. Just ask.

The AWS FinOps Agent tells you something changed. CloudFix tells you what to fix, how much you’ll save, and gives your agent the evidence to act on it.

Where RightSpend Fits

Even with AWS’s own agent and CloudFix’s fix list, you still need rate optimization. Agents find waste. They don’t negotiate pricing.

RightSpend gives you Reserved Instance-level pricing on EC2 with zero commitment. Hourly rebalancing, no lock-in, 15-minute setup. It works alongside any FinOps agent. Use AWS FinOps Agent for anomaly investigation. Use CloudFix for validated fixes. Use RightSpend for the best possible price on the compute you’re already running.

Three Questions to Ask

If you’re sorting through the FinOps agent wave this week:

  1. Does the agent find new savings, or just make existing data easier to read? Anomaly investigation is useful. It’s not optimization.
  2. Does it require commitments to deliver savings? Fewer than half of AWS orgs use RIs or Savings Plans. If you’re in the other 50%, commitment optimizers can’t help you.
  3. Can your own AI agent access it? MCP support means you use whatever agent you already work with. You’re not locked into someone else’s chat interface.

AWS FinOps Agent is a welcome addition to the toolkit. Use it for what it’s good at: anomaly investigation. Then ask what actually reduces your bill.
