✨ Key Features

  • Zero-Boilerplate Discovery: No need to maintain hundreds of lines in ~/.aws/config. Enter your SSO Start URL once, and all authorized accounts and roles are loaded dynamically.

  • Smart Role Prioritization (MRU): Automatically pins your most recently used roles (e.g. QA Admin, Prod Admin) to #1 and #2. Pressing Enter logs you in within 1 second.

  • 🔍 Interactive Substring Search: Type any keyword (prod, qa, admin, gpu, eks) at the selection prompt to instantly filter dozens of accounts.

  • 🤖 Native Model Context Protocol (MCP) Server: Expose AWS profile switching, caller identity, and EC2/EKS exploration to LLM pair programmers (Claude Desktop, Cursor, Antigravity, Gemini).

  • 🔒 Enterprise-Grade Security: Strict POSIX 0600 file permissions, atomic file replacement (os.replace), and 300-second expiration safety margins.

  • 🌐 WSL2 Seamless Browser Bridge: Automatically detects WSL2 and opens authorization URLs directly in your Windows host browser.

  • ☸️ DevOps Acceleration: Instant EC2 SSM shell sessions and 1-click Amazon EKS kubeconfig context switching.

🚀 Quick Start

1. Interactive Login

aws-auth
Available account-role combinations (Showing 1-10 of 18):
+-----+------------------------------+-----------------+------------------------------+-------------+
| #   | Account                      | Account ID      | Role                         | Region      |
+-----+------------------------------+-----------------+------------------------------+-------------+
| 1   | ⭐ Production-App (PROD)        | (111222333444)  | AdministratorAccess     | us-east-1   |
| 2   | ⭐ Staging-Web (QA)          | (555666777888)  | AdministratorAccess     | us-east-1   |
| 3   | Analytics-Data                  | (999888777666)  | AdministratorAccess     | us-east-1   |
...
Select number 1-10 (default: 1) (type keyword to filter): [ENTER]

✅ Profile 'production-app-admin' set as default in ~/.aws/credentials.

2. Configure Portal & Custom Aliases

aws-auth --configure

Customize environment labels and preferred accounts in ~/.aws-auth/config.json:

{
  "sso_start_url": "https://my-company.awsapps.com/start",
  "sso_region": "us-east-1",
  "preferred_accounts": ["Staging-Web", "Production-App"],
  "aliases": {
    "555666777888": "QA",
    "111222333444": "PROD"
  }
}

🤖 AI Agent Integration (Model Context Protocol)

aws-auth runs as a high-performance MCP Server over stdio.

Add to Claude Desktop (claude_desktop_config.json) or Cursor:

{
  "mcpServers": {
    "aws-auth": {
      "command": "aws-auth",
      "args": ["--mcp"]
    }
  }
}

What AI Assistants Can Do with aws-auth:

  • Check active AWS Account, Region, and IAM Role ARN (aws_get_caller_identity).

  • Switch active AWS profile (aws_switch_profile) without human intervention.

  • Inspect running EC2 instances and Amazon EKS clusters (aws_list_ec2_instances, aws_list_eks_clusters).

  • Update local Kubernetes context (aws_update_kubeconfig).
