Claude Aws

PyPI version Python License: MIT

An MCP server that lets you control AWS resources directly from Claude Desktop or Claude Code using natural language.

Setup

Step 1. Create a .env file in your working directory:

AWS_ACCESS_KEY_ID=your_access_key
AWS_SECRET_ACCESS_KEY=your_secret_key
AWS_DEFAULT_REGION=ap-northeast-2

Step 2. Run the MCP server:

aws-mcp

Claude Desktop Integration

Config file location:

OS	Path
Windows	%APPDATA%\Claude\claude_desktop_config.json
Mac	~/Library/Application Support/Claude/claude_desktop_config.json

Add this to claude_desktop_config.json:

{
  "mcpServers": {
    "aws": {
      "command": "aws-mcp",
      "env": {
        "AWS_ACCESS_KEY_ID": "your_access_key",
        "AWS_SECRET_ACCESS_KEY": "your_secret_key",
        "AWS_DEFAULT_REGION": "ap-northeast-2"
      }
    }
  }
}

Restart Claude Desktop — the AWS tools will appear automatically.
