• save_estimate: Save estimate to AWS and get shareable URL

• get_region_name: Convert AWS region codes to display names

Installation

Prerequisites

• Python 3.10 or higher

• uv package manager

Install uv

# macOS/Linux

Run the MCP Server

The server is designed to be run via uvx directly from GitHub (no installation needed):

uvx --from git+https://github.com/elchanio-76/aws-pricing-calculator-mcp aws-pricing-calculator-mcp

Or install it globally:

uv tool install git+https://github.com/elchanio-76/aws-pricing-calculator-mcp

Once published to PyPI, you can use the simpler form:

uvx aws-pricing-calculator-mcp

Usage with Kiro

This MCP server is designed to work with the AWS Pricing Calculator Power for Kiro.

Configuration

Add to your Kiro MCP configuration (.kiro/settings/mcp.json):

{
  "mcpServers": {
    "aws-pricing-calculator": {
      "command": "uvx",
      "args": ["--from", "git+https://github.com/elchanio-76/aws-pricing-calculator-mcp", "aws-pricing-calculator-mcp"],
      "disabled": false
    }
  }
}

Or if published to PyPI:

{
  "mcpServers": {
    "aws-pricing-calculator": {
      "command": "uvx",
      "args": ["aws-pricing-calculator-mcp"],
      "disabled": false
    }
  }
}

Or install the Kiro Power which includes this configuration automatically.

Setup

# Clone the repository
git clone https://github.com/elchanio-76/aws-pricing-calculator-mcp.git
cd aws-pricing-calculator-mcp

# Install dependencies
uv pip install -e .

Testing

# Run tests
python3 test_mcp_server.py

# Test via stdio

python3 -m mcp_server.server

Architecture

The MCP server wraps existing Python scripts that handle:

• CloudFront API calls for service definitions

• Estimate JSON generation

• AWS Save API integration

All scripts use curl subprocess to avoid Python SSL issues with CloudFront.
