AWS Cost Explorer MCP Server
AWS Cost Explorer MCP server enabling AI agents to query and analyze AWS cloud spending — retrieving cost and usage data by service, account, region, and time period; identifying cost anomalies; analyzing spending trends; and integrating AWS Cost Explorer capabilities into agent-driven FinOps and cloud cost optimization workflows.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
TLS via AWS SDK. Read-only IAM permissions for Cost Explorer API. SOC2, ISO27001. Community MCP server. Use minimal read-only IAM policy. API calls cost $0.01 each — monitor usage.
⚡ Reliability
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
Interface
Authentication
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
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.
Agent Metadata
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
