Best When

An agent needs to analyze or report on AWS cloud spending — for FinOps, budget tracking, cost optimization recommendations, or chargeback reporting.

Avoid When

You're using Azure, GCP, or multi-cloud platforms — or if you need real-time cost alerts rather than historical analysis.

Use Cases

  • Querying AWS spending by service and time period from FinOps agents
  • Identifying cost anomalies and unexpected charges from cost monitoring agents
  • Analyzing reserved instance and savings plan coverage from optimization agents
  • Comparing spend across AWS accounts from multi-account management agents
  • Building cost attribution reports by tag from chargeback agents
  • Forecasting future AWS costs from budget planning agents

Not For

  • Teams not using AWS (use Azure Cost Management or GCP Billing MCPs)
  • Real-time cost alerts (use AWS Budgets or CloudWatch alarms for alerts)
  • Actual billing adjustments or payment management

AWS IAM credentials (access key + secret, or IAM role). Requires ce:GetCostAndUsage, ce:GetCostForecast permissions. Read-only cost access — no billing modification permissions needed.

Pricing

Model: usage-based
Free tier: No
Requires CC: Yes

Cost Explorer API charges $0.01 per request — agents making many queries can incur costs. Console/UI is free but API is not. AWS account required.

Known Gotchas

  • Cost Explorer API charges $0.01/request — agents must not make excessive calls
  • Cost data has 24-48 hour delay — no real-time cost visibility
  • Time period granularity (DAILY vs MONTHLY) dramatically affects result set size
  • GroupBy dimensions must match available Cost Explorer dimensions
  • Cost allocation tags must be activated in AWS console before they appear in queries
  • Community MCP server — limited to cost query features; no budget or alert management
