Discover more about what's new at AWS with The AWS MCP Server now supports cross-account and cross-role access

AWS' platform is a leading cloud computing platform, offering insights into cloud infrastructure, services, and solutions for developers, businesses, and IT professionals. Through articles, whitepapers, and documentation, AWS offers insights into cloud architecture, serverless computing, and machine learning on AWS. Developers and architects can learn about AWS services like EC2, S3, Lambda, and more to build scalable, secure, and cost-effective cloud applications.

AWS has added cross-account and cross-role access to the AWS MCP Server, part of the Agent Toolkit for AWS. Developers using AI coding agents like Kiro, Claude Code, or Codex can now work across multiple AWS accounts and IAM roles within a single session without restarting. Previously, switching profiles required stopping the session, updating credentials, and restarting the server. Now, each command can specify a profile, enabling seamless switching between accounts and roles. This is useful for scenarios like querying CloudWatch logs across production and staging accounts or updating Lambda and S3 configurations in different accounts within the same conversation.
