aws-calculator-mcp

MCP server for AWS Pricing Calculator. Create cost estimates through natural language, get shareable links, retrieve actual AWS-calculated costs.

436 services, 72 regions
Real pricing via headless Chrome (not approximations)
Savings Plans, Reserved Instances, all pricing models
No AWS credentials required

Install

Add to your MCP client config:

{
  "mcpServers": {
    "aws-calculator": {
      "command": "npx",
      "args": ["-y", "aws-calculator-mcp@latest"]
    }
  }
}

Client	Config file
Kiro	`~/.kiro/settings/mcp.json`
Claude Desktop (macOS)	`~/Library/Application Support/Claude/claude_desktop_config.json`
Claude Desktop (Windows)	`%APPDATA%\Claude\claude_desktop_config.json`
Cursor	`.cursor/mcp.json`
VS Code	`.vscode/mcp.json`

Requires Node.js ≥ 18. Chrome optional (only for cost retrieval).

What it does

You ask your AI assistant to estimate AWS costs. The MCP handles the rest:

Searches the AWS service catalog
Looks up valid configuration fields
Builds the estimate incrementally
Exports to calculator.aws (shareable link)
Opens the link in headless Chrome to get actual calculated costs

The pricing is identical to calculator.aws because it is calculator.aws doing the math.

Tools

Tool	Purpose
`search_services`	Find services by keyword
`get_service_fields`	Get valid config fields for a service
`create_estimate`	Start a new estimate
`add_service`	Add configured services
`update_service`	Modify a service in-place
`export_estimate`	Get a shareable calculator.aws URL
`refresh_estimate`	Get actual costs via headless Chrome
`generate_report`	Per-service cost breakdown (CSV/Markdown)
`import_estimate`	Download an existing estimate

Example

"Estimate a production stack in us-west-2: 2x c5.xlarge EC2 with Savings Plan, Lambda at 20M requests, S3 500GB, CloudFront 1TB"

→ Returns a calculator.aws link + $333.92/mo breakdown by service.

How it works

Your prompt → Agent configures services → MCP packages payload → calculator.aws saves it
                                                                → Chrome opens it → scrapes real costs

No local price calculations. No hardcoded rates. The AWS calculator frontend computes everything.

Requirements

Node.js ≥ 18
Chrome (optional) — for refresh_estimate and generate_report. Install with npx puppeteer browsers install chrome or use system Chrome.
