AWS aws-mcp high security documentation change

Service: aws-mcp · 2025-12-10 · Security-related high

File: aws-mcp/latest/userguide/getting-started-aws-mcp-server.md

Summary

Multiple changes: authentication troubleshooting note, corrected installation commands, policy action name fix, and URL updates

Security assessment

The change to policy action 'aws-mcp:InvokeMcp' fixes a typo that could have caused misconfigured IAM policies, potentially leading to authorization issues. The installation command changes (piping to 'sh'/'iex' instead of 'less'/'more') improve correctness but introduce security implications if the script source is untrusted (though AWS documentation is trusted).
