## What it does

This server connects an AI coding agent directly to AWS billing endpoints. It extracts cost numbers from Cost Explorer, highlights unused resources, and turns raw statements into plain summaries for Slack. Built-in caching stops repetitive queries from inflating AWS API costs.

The setup deploys two companion components: the `aws-billing-cli` helper and the `aws-billing-mcp` binary. To query billing figures, you must supply active Amazon Web Services credentials on your local machine.

Running the connector with `--transport http` presents clear security risks. That mode currently lacks authentication, binds to every network interface, and exposes your credentials to local browser requests. Stick strictly to standard `stdio` transport until an updated release ships.

## Requirements
- Environment variables: `AWS_ACCESS_KEY_ID`, `AWS_BILLING_BASE_URL`, `AWS_BILLING_SLACK_CHANNEL`, `AWS_REGION`, `AWS_SECRET_ACCESS_KEY`, `AWS_SESSION_TOKEN` — keys and tokens: ask the human for the values, never commit them or put them in shared files.
- Works with: AWS

## Install

### Claude Code (native platform)

**Install**
- The MCP registry has no launch command for it: see the repository README

## When to use it
- break down complex AWS invoices without deep cloud expertise
- detect idle resources and wasteful cloud expenditures
- cache queries to prevent repeated AWS Cost Explorer API charges
- format and dispatch readable billing summaries directly to Slack

## Example prompts
- Analyze last month's AWS Cost Explorer data and point out wasteful spend
- Generate a plain-text billing summary and format it for Slack
- Check recent cloud charges and identify which services cost the most
