What is AWS Pricing MCP Server?

AWS Pricing MCP Server is a specialized MCP server that allows AI assistants and applications to access detailed, up-to-date AWS service pricing information and perform cost estimations via standardized endpoints. By connecting through the Model Context Protocol, it empowers agents to answer questions, generate budget analyses, and help with AWS cost planning directly from your development environment, chat interface, or workflow automations.

How to Configure

  1. Install prerequisites: Ensure uv (from Astral) and Python 3.10+ are installed.
  2. Configure AWS credentials: The server requires appropriate AWS credentials with permission to query pricing APIs. Use environment variables or AWS profiles as needed.
  3. Add to MCP client configuration: In your MCP client (e.g., Amazon Q CLI, Cursor, Cline), update the MCP config file (such as ~/.aws/amazonq/mcp.json, .cursor/mcp.json, etc.) with the following entry: 
    {
  "mcpServers": {
    "awslabs.aws-pricing-mcp-server": {
      "command": "uvx",
      "args": [
        "awslabs.aws-pricing-mcp-server@latest"
      ],
      "env": {
        "AWS_PROFILE": "your-aws-profile",
        "FASTMCP_LOG_LEVEL": "ERROR"
      }
    }
  }
}
  4. Restart your MCP-enabled client to pick up the new server.
  5. (Optional) For containerized setups, configure your Docker environment with the necessary AWS credentials and mount shared configuration as needed.

How to Use

  1. In your supported AI assistant (Amazon Q Developer CLI, Cursor, Cline, Claude Desktop, etc.), initiate a chat or workflow session.
  2. Reference AWS Pricing MCP Server by name, or use natural language (e.g., "Estimate the monthly AWS cost for a t3.large EC2 instance and an RDS MySQL db.m5.large in us-east-1").
  3. The assistant will discover and invoke pricing tools exposed by the AWS Pricing MCP Server, retrieve pricing information, and return cost breakdowns or recommendations.
  4. You can explicitly prompt: "Using the AWS Pricing MCP Server, generate a budget estimate for the following architecture..." or let the agent select the relevant tool based on your context.
  5. Tool invocations and results can be auto-approved, or you may choose to review and approve each tool call.

Key Features

  • Up-to-date AWS pricing data: Access latest prices for EC2, S3, RDS, Lambda, and more, synced directly from AWS public APIs.
  • Cost estimation: Generate precise monthly or yearly infrastructure cost forecasts based on your chosen resource types and usage assumptions.
  • Budget planning: Analyze the impact of architectural changes on projected AWS expenses.
  • Cost breakdowns: Get granular cost components for complex deployments, supporting clear decision-making.
  • Integration with AI workflows: Seamlessly expose pricing info to LLM agents, enabling contextual cost guidance and automation in real-time.
  • Automated updates: Always utilizes current pricing, minimizing risks from outdated quotes.

Use Cases

  • Cloud cost estimation: Before deployment, estimate monthly or annual AWS bills for proposed infrastructure, including compute, database, and storage.
  • Budget reviews/approval: Enable development teams to justify architecture choices with transparent price analyses.
  • What-if analysis: Quickly compare cost impacts of different instance types, regions, or services.
  • CI/CD pipeline cost checks: Integrate with automation to warn if planned changes will violate project budgets.
  • Conversational assistants and chatbots: Instantly answer business and technical pricing questions—"How much would this solution cost monthly?"

FAQ

Q: Does AWS Pricing MCP Server include regional price differences?
Yes, it supports region-specific pricing and reflects the latest variances in cost across AWS regions.

Q: How accurate are the cost estimates?
All estimates are based on current AWS public pricing APIs. Actual costs may vary if you have custom enterprise pricing or discounts.

Q: Can I estimate pricing for multiple resources or architectures together?
Absolutely—describe your stack (e.g., "2 t3.medium instances, 1 RDS db.t4g.large, 100GB S3 storage") and the server will generate an itemized estimate.

Q: Is this tool safe to run with my AWS credentials?
The server only needs read access to AWS public APIs for pricing and does not modify resources. Follow security best practices for credential management.

Q: Can I use the Pricing MCP Server offline?
The service requires internet access to fetch the latest AWS pricing data and cannot operate fully offline.
