At a Glance & Executive Verdict
MCP Server Aws Sso
Cloud Platforms · Local stdio
Quality: 63/100 (Good) | Auth: OAuth 2.0
AGTS MCP Server
Cloud Platforms · Remote HTTP/SSE
Quality: 48/100 (Fair) | Auth: No auth required
Verdict Summary: Choose MCP Server Aws Sso if you need specialized Cloud Platforms tools running via a local process. Choose AGTS MCP Server if your workspace requires Cloud Platforms integration with remote web transport. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose MCP Server Aws Sso when:
You need dedicated capabilities in the Cloud Platforms domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: OAuth 2.0 (Free / Open Source).
You have access to required keys: AWS_SSO_START_URL, AWS_SSO_REGION, AWS_REGION.
AWS Single Sign-On (SSO) integration enabling AI systems to securely interact with AWS resources by initiating SSO login, listing accounts/roles, and executing AWS CLI commands using temporary credentials.
Sovereign MCP Gateway — 64 governed tools with Merkle transparency log. EU AI Act ready.
Initiate AWS SSO device authorization flow to obtain temporary credentials.
This flow works as follows:
1. Generates a unique user verification code and authentication URL
2. Opens a browser to AWS SSO login page (if `launchBrowser: true`)
3. You enter the verification code and complete AWS SSO login
4. Background polling automatically collects and caches the token
5. The cached token is used by other AWS SSO tools
**IMPORTANT FOR AI ASSISTANTS**: When the tool returns authentication instructions:
- ALWAYS check if a browser window opened automatically
- If browser opened: Guide the user to complete authentication
- If no browser opened: Instruct user to manually open the URL and enter code
- Always provide both the verification code and URL as backup
Prerequisites:
- AWS SSO must be configured with a start URL and region
- Browser access is required for authentication
- You must have an AWS SSO account with appropriate permissions
Returns: Authentication status, session details, verification code and URL
aws_sso_status
Check current AWS SSO authentication status.
Verifies if a valid cached token exists and its expiration time. Does NOT perform authentication - only checks status. If no valid token exists, instructs you to run `aws_sso_login`.
Use before calling `aws_sso_ls_accounts` or `aws_sso_exec_command`.
Returns: Authentication status, session details, expiration time, next steps
aws_sso_ls_accounts
List all AWS accounts and roles accessible through AWS SSO.
Provides essential information needed for `aws_sso_exec_command`:
- Fetches all accessible accounts with IDs, names, and emails
- Retrieves all available roles for each account
- Handles pagination internally
- Caches account and role information
Prerequisites:
- MUST first authenticate using `aws_sso_login`
- AWS SSO must be configured with a start URL and region
Returns: Account list with IDs, names, roles, and session status
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
MCP Server Aws Sso is categorized under Cloud Platforms and uses a local stdio subprocess. In contrast, AGTS MCP Server belongs to Cloud Platforms using remote streaming HTTP/SSE transport. Select MCP Server Aws Sso when you need capabilities focused on cloud platforms and AGTS MCP Server when you require tools for cloud platforms.
Execute AWS CLI command using temporary credentials from AWS SSO.
Workflow:
1. Verifies valid AWS SSO authentication token
2. Obtains temporary credentials for account and role
3. Executes the AWS CLI command
4. Caches credentials for future use (1 hour)
Prerequisites:
- MUST first authenticate using `aws_sso_login`
- AWS CLI MUST be installed on the system
- AWS SSO must be configured
Required: `accountId`, `roleName`, `command`
Optional: `region`
Returns: Execution context, command output, errors, exit code
aws_sso_ec2_exec_command
Execute shell command on EC2 instance via SSM using AWS SSO credentials.
No SSH access or inbound ports required. Uses SSM's RunShellScript document.
Prerequisites:
- MUST first authenticate using `aws_sso_login`
- EC2 instance MUST have SSM Agent installed
- Instance needs IAM role with AmazonSSMManagedInstanceCore policy
- Your role needs `ssm:SendCommand` and `ssm:GetCommandInvocation` permissions
Required: `instanceId`, `accountId`, `roleName`, `command`
Optional: `region`
Returns: Execution context, command output, errors, troubleshooting guidance
