AWS Billing and Cost Management MCP Server

MCP server for accessing AWS Billing and Cost Management capabilities.

Important Note: This server accesses cost and usage data from AWS Billing and Cost Management APIs. All API calls are performed using the caller's AWS credentials and follow AWS service limits and quotas.

Features

AWS Free Tier

• Free Tier optimization: Monitor Free Tier usage and avoid unexpected charges

AWS Cost and Usage Analysis

• Cost Explorer insights: Analyze historical and forecasted AWS costs with flexible grouping and filtering
• Usage metrics analysis: Track resource usage trends across your AWS environment
• Budget monitoring: Check existing budgets and their status against actual spending, plus their configured enforcement actions and alert notifications (per-budget or account-wide)
• Cost anomaly detection: Identify unusual spending patterns and their root causes

Cost Optimization Recommendations

• Compute Optimizer recommendations: Get right-sizing suggestions for EC2, Lambda, EBS, and more
• Cost Optimization Hub: Access cost-saving opportunities across your AWS environment

Savings Plans and Reserved Instanaces

• Reserved Instance planning: Analyze RI coverage and receive purchase recommendations
• Savings Plans performance: Analyze how much eligible spend existing plans cover and how much of their commitment is consumed over a lookback window
• Savings Plans inventory: Describe the plans an account owns with their state, term, payment option, commitment, and expiry, including the queued, returned, and payment-failed plans that Cost Explorer does not report
• Savings Plans rates and offerings: Look up the rates locked in on plans already owned, and the offerings available to purchase with their rates, to compare terms and payment options against real numbers
• Savings Plans recommendations: Get personalized purchase recommendations based on usage patterns, the hourly data-points behind a recommendation, and the history of when recommendations were generated
• Savings Plans purchase analysis: Run Purchase Analyzer what-if analyses — maximum savings, a specific commitment, or a target average coverage — and retrieve the projected cost, coverage, and utilization once an analysis completes

S3 Storage Lens Analysis

• Storage metrics querying: Run SQL queries against Storage Lens metrics data
• Storage cost breakdown: Analyze S3 storage costs by bucket, storage class, and region
• Storage optimization opportunities: Identify lifecycle policy opportunities and cost-saving measures

• Pricing rules and plans: List pricing rules (MARKUP, DISCOUNT, TIERING) and pricing plans with their associations
• Custom line items: List custom cost allocations including support fees, shared service costs, taxes, credits, and RI/SP distribution

Cost Allocation Tags

• Tag activation status: List cost allocation tags with filters by status (Active/Inactive), type (AWSGenerated/UserDefined), and specific tag keys
• Backfill history: Retrieve the history of tag backfill requests that retroactively apply activation status to historical billing data

Cost Category Definitions

• Describe cost categories: Get the full definition of a cost category including rules, split charge rules, and processing status
• List cost categories: List all cost category definitions in the account with summary metadata and filtering by effective date or supported resource types

AWS Invoicing

• Invoice summaries: List invoice-level details (invoice ID, type, billing period, issued/due dates, issuing entity, and amounts with discount/tax/fee breakdowns across base, tax, and payment currencies) for an account or a single invoice, filtered by month or date range
• Invoice units: List and retrieve invoice unit definitions (groups of accounts that receive a separate invoice, with their receiver account and linked-account rules), filtered by name, receiver, or member account; and fetch invoice receiver profiles (legal name, address, tax registration number) for a set of accounts
• Procurement portal preferences: List and retrieve procurement portal connections (SAP Business Network, Coupa) and e-invoice delivery / purchase-order retrieval settings

Specialized Cost Optimization Prompts

• Graviton migration analysis: Guided analysis to identify EC2 instances suitable for AWS Graviton migration
