AWS MCP Server

AWS maintains a whole set of MCP servers in one repo — not a single server. There's one for official docs, one for costs, one for generating CDK code, and several for specific services. You install the ones you need rather than all of them.

The two most useful are usually the docs server and the cost server: the first stops your AI from inventing service limits when answering AWS questions, the second lets you just ask "what did we spend the most on this month?"

What it does for you

Lets your AI operate AWS — inspect resources, check bills, manage services, doing cloud ops through chat (spans AWS's official MCP suite).

Capabilities

Query AWS resources and status
View cost and billing

Once installed, try asking your AI

Say this directly in Claude / Cursor or any client with this server connected

›“How much did AWS cost this month? Which service is most expensive?”

Install / Connect

# No npm package — install from source.
# See the repo's README for the exact command:
# https://github.com/awslabs/mcp

Follow the official README; env and args vary per server.

Why use it

Good for: people doing architecture and ops on AWS, especially anyone who's been burned by an AI hallucinating service quotas.

Before connecting: the servers that touch real resources need AWS credentials. Use a least-privilege IAM role — read-only policies for read-only use cases.
