[Kiro FinOps] Automating AWS Pricing Collection with AWS Pricing MCP Server
Key Takeaways
This article explains how to streamline AWS cost estimation by combining the AI agent "Kiro" with the "AWS Pricing MCP Server."
- Leveraging AWS Pricing MCP Server: Access real-time AWS service pricing for complex filtering and cost analysis.
- Natural Language Pricing Queries: Obtain instance rates and monthly estimates through conversation without manual Pricing Calculator entry.
- Accuracy Verification: Highlights the importance of comparing AI-generated results with the actual Calculator to ensure precision.
Introduction
Hello, I'm Miura from the DX Solution Division.
How do you handle AWS cost estimations? Manually clicking through the Pricing Calculator can be tedious, given the numerous parameters required.
Even when asking an AI, you might find significant gaps compared to actual prices or a lack of clear evidence. In this post, I will introduce a method to calculate accurate costs by integrating the AWS Pricing MCP Server with Kiro.
What is AWS Pricing MCP Server?
The AWS Pricing MCP Server is an MCP server that provides access to real-time AWS pricing information and cost analysis capabilities.
Key Features
- Service Exploration: Discover and retrieve pricing for all AWS services.
- Attribute Identification: Pinpoint conditions like instance types, regions, and storage classes.
- Real-time Queries: Access the latest price data using advanced filtering.
- Cross-region Comparison: Compare prices across different regions with a single query.
- Cost Analysis Reports: Generate detailed reports including unit prices and calculation breakdowns.
- Infrastructure Project Analysis: Automatically identify AWS services from CDK or Terraform projects.
For installation and configuration details in Kiro, please refer to the links below.
Getting Started
Before using the server, ensure the following prerequisites are met:
- AWS CLI configuration file is created (~/.aws/credentials).
- The "AWS_PROFILE" in the MCP server settings is set to the appropriate profile.
Querying EC2 Pricing
Let's retrieve the On-Demand pricing (USD/h) for a specific instance type (e.g., t3.micro) and have it calculate a monthly estimate (assuming 730h/month).
Prompt
Use the MCP `awslabs.aws-pricing-mcp-server` to get EC2 On-Demand pricing. Conditions: - region: ap-northeast-1 (Tokyo) - instanceType: t3.micro - operatingSystem: Linux - SP/RI: NA Format the output as: - Unit Price (JPY/hour) **1USD=160JPY** - Monthly Cost (JPY/month) *Estimated at 730 hours/month - Specify region, currency, and source (PriceList API/SKU) - List prerequisites at the end (hours, currency, tax excluded/included, etc.)
Kiro called the MCP and calculated the price instantly. The evidence is clear as detailed information is included.
Verifying AI Results (Bonus)
Instead of blindly trusting the AI, let's verify the results with the actual Pricing Calculator.
The On-Demand cost per hour (0.0136 USD) matched. However, checking the monthly calculation...
Formula: 9.93(USD/month) × 160 = 1,588.8(JPY/month)
Kiro's answer was "15,885 JPY/month," meaning it misplaced a decimal point.
AI can make mistakes like this. If something feels off, it's crucial to point it out and have it corrected immediately.
Summary
By introducing the AWS Pricing MCP Server to Kiro, you can now calculate usage fees instantly just by providing the necessary parameters. This is expected to significantly reduce the man-hours involved in AWS operations.
The possibilities are broad, from fixing output formats with AGENT STEERING to deep-diving into conditions through dialogue. However, given the risk of hallucination, always double-check for critical estimates.
