AWS FinOps MCP Server

An MCP (Model Context Protocol) server that brings powerful AWS FinOps capabilities directly into your AI assistant. Analyze cloud costs, audit for waste, and get budget insights using natural language, all while keeping your credentials secure on your local machine.

Why Use the AWS FinOps MCP Server?

Managing AWS costs can be complex. Finding answers to questions like "What did we spend on S3 last month?" or "Do we have any unused EC2 instances?" often requires navigating the AWS Console or writing scripts.

This server bridges that gap by connecting the powerful, natural language understanding of an LLM directly to your AWS account's financial data. You can ask complex questions and get immediate, actionable insights without ever leaving your chat interface.

Use Cases:

> Prompt on Claude Desktop: "Get usage-type based cost for all my AWS CLI profiles for the last 90 days. And get the audit report for all profiles for region ap-south-1. Make a finops report with data in minimalistic way and keep it professional."

> Prompt on Amazon Q CLI: "Could you use aws-finops mcp server and get cost data for each month in the last 6 months for profile 04 and present the data in a tabular format highlighting how the total cost and cost for each service has changed every month?"

> Prompt on Claude Desktop: "Generate a comprehensive finops report for management using all the tools available in the AWS FinOps MCP server. Use all the available CLI profiles and use the region ap-south-1 wherever required."

Key Features

- Detailed Cost Analysis: Query your AWS cost data using tags, time ranges, and service groupings.
- Automated FinOps Audit: Instantly find common sources of cloud waste, such as stopped EC2 instances, unattached EBS volumes, and unassociated Elastic IPs etc.
- Budget Monitoring: Check the status of your AWS Budgets to see if you are on track, over budget, or forecasted to exceed your limits.
- Multi-Profile & Multi-Region: Seamlessly query across any or all of your configured AWS accounts and regions in a single command.
- Secure by Design: Your AWS credentials never leave your machine. The server runs locally and uses your existing AWS CLI configuration to make API calls directly to AWS.

Prerequisites

General Requirements

- Python 3.10+: Ensure you have a compatible Python version installed.
- MCP Client: An application that supports MCP. This guide uses Claude for Desktop as the example.

AWS Requirements & IAM Permissions

- AWS CLI: The AWS CLI must be installed on your machine.
- AWS Account & Profile(s): You need at least one configured AWS profile.
- IAM Permissions: The AWS identity (IAM User or Role) associated with your profile(s) requires specific read-only permissions to function correctly.

Create an IAM policy with the following JSON and attach it to your user or role. These permissions are read-only and grant access only to the necessary services.
