Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

A Model Context Protocol (MCP) server that enables AI assistants like Claude to interact with your AWS environment. This allows for natural language querying and management of your AWS resources during conversations. Think of better Amazon Q alternative.

Features

  • 🔍 Query and modify AWS resources using natural language
  • ☁️ Support for multiple AWS profiles and SSO authentication
  • 🌐 Multi-region support
  • 🔐 Secure credential handling (no credentials are exposed to external services, your local credentials are used)
  • 🏃♂️ Local execution with your AWS credentials

Prerequisites

Installation

  1. Clone the repository:
git clone https://github.com/RafalWilinski/aws-mcp
cd aws-mcp
  1. Install dependencies:
pnpm install
# or
npm install

Usage

  1. Open Claude desktop app and go to Settings -> Developer -> Edit Config

  1. Add the following entry to your claude_desktop_config.json:
{
"mcpServers": {
"aws": {
"command": "npm", // OR pnpm
"args": [
"--silent",
"--prefix",
"/Users//aws-mcp",
"start"
]
}
}
}

Important: Replace /Users//aws-mcp with the actual path to your project directory.

  1. Restart Claude desktop app. You should see this:

  1. Start by selecting an AWS profile or jump to action by asking:
  2. "List available AWS profiles"
  3. "List all EC2 instances in my account"
  4. "Show me S3 buckets with their sizes"
  5. "What Lambda functions are deployed in us-east-1?"
  6. "List all ECS clusters and their services"

Questions

What is the Aws MCP server?

Talk with your AWS using Claude. Model Context Protocol (MCP) server for AWS. Better Amazon Q alternative.

What tools does Aws expose?

3 in total: 2 read-only, 1 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.

Is Aws safe to connect to an agent?

The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.

What credentials does Aws need?

No credential environment variables were found in its source, so it appears to need none.

How does Aws run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as chatwithcloud-mcp at 1.0.0.

How current is this page?

The grade is for one exact copy of the source (12e600b7f4d1), read on 2026-10-05. The repository is watched and re-audited when it changes.
