Node.js/TypeScript MCP server for AWS Single Sign-On (SSO). Enables AI systems (LLMs) with tools to initiate SSO login (device auth flow), list accounts/roles, and securely execute AWS CLI commands using temporary credentials. Streamlines AI interaction with AWS resources.
Config is the same across clients — only the file and path differ.

Add this badge to your README to show your security score and help users find safe servers.
Transform how you manage and access your AWS infrastructure by connecting Claude, Cursor AI, and other AI assistants directly to your AWS accounts through AWS IAM Identity Center (formerly AWS SSO). Get instant access to your cloud resources, execute commands, and manage EC2 instances using natural language.
Run this in your terminal to verify the server starts. Then let us know if it worked — your result helps other developers.

Transform how you manage and access your AWS infrastructure by connecting Claude, Cursor AI, and other AI assistants directly to your AWS accounts through AWS IAM Identity Center (formerly AWS SSO). Get instant access to your cloud resources, execute commands, and manage EC2 instances using natural language.
✅ Ask AI about your AWS accounts: "Show me all my AWS accounts and available roles"
✅ Execute AWS commands: "List all S3 buckets in my production account"
✅ Manage EC2 instances: "Check the disk usage on server i-123456789"
✅ Access multi-account setups: "Switch to the staging account and describe the VPCs"
✅ Monitor resources: "Get the status of all running EC2 instances"
✅ Run shell commands: "Execute 'df -h' on my web server via SSM"
Get up and running in 2 minutes:
Set up AWS IAM Identity Center:
https://your-company.awsapps.com/start)# Set your AWS SSO configuration
export AWS_SSO_START_URL="https://your-company.awsapps.com/start"
export AWS_REGION="us-east-1"
# Start the authentication flow
npx -y @aashari/mcp-server-aws-sso login
# List your accessible accounts and roles
npx -y @aashari/mcp-server-aws-sso ls-accounts
# Execute an AWS command
npx -y @aashari/mcp-server-aws-sso exec-command \
--account-id 123456789012 \
--role-name ReadOnly \
--command "aws s3 ls"
Add this to your Claude configuration file (~/.claude/claude_desktop_config.json):
{
"mcpServers": {
"aws-sso": {
"command": "npx",
"args": ["-y", "@aashari/mcp-server-aws-sso"],
"env": {
"AWS_SSO_START_URL": "https://your-company.awsapps.com/start",
"AWS_REGION": "us-east-1"
}
}
}
}
Restart Claude Desktop, and you'll see "🔗 aws-sso" in the status bar.
Most AI assistants support MCP. Install the server globally:
npm install -g @aashari/mcp-server-aws-sso
Then configure your AI assistant to use the MCP server with STDIO transport.
Create ~/.mcp/configs.json for system-wide configuration:
{
"aws-sso": {
"environments": {
"AWS_SSO_START_URL": "https://your-company.awsapps.com/start",
"AWS_REGION": "us-east-1",
"DEBUG": "false"
}
}
}
Alternative config keys: The system also accepts "@aashari/mcp-server-aws-sso" or "mcp-server-aws-sso" instead of "aws-sso".
Ask your AI assistant:
