AWS Cost Operations

MCP Server

Command: uvx awslabs.cost-explorer-mcp-server@latest (stdio transport)
Requires: AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_REGION (or AWS_PROFILE)
Note: Cost Explorer API charges $0.01 per request — be mindful of query volume

Key Capabilities

Cost breakdown: Spending by service, account, region, or tag
Time series: Daily, monthly, or custom date range cost trends
Forecasts: Predicted spend based on historical patterns
Anomaly detection: Unusual spending spikes
Filtering: Narrow by service (EC2, VPC, TGW, NAT GW, VPN, etc.)

Workflow: Network Cost Analysis

When a user asks "how much is our AWS network costing?":

Total network spend: Cost breakdown for VPC, Transit Gateway, NAT Gateway, VPN, ELB, Direct Connect
Trend: Monthly trend for network services over last 6 months
Top services: Rank network services by spend (NAT GW data processing is often #1)
Per-region: Break down network costs by region
Forecast: Projected network spend for next month
Report: Network cost dashboard with optimization recommendations

Workflow: Cost Anomaly Investigation

When investigating unexpected charges:

Daily breakdown: Get daily costs for the spike period
Service drill-down: Which service caused the spike?
Region check: Was the spike in a specific region?
Correlate: Cross-reference with CloudTrail for resource creation events
Report: Root cause and recommended action

Workflow: Monthly Cost Review
