# The AWS MCP Server now supports cross-account and cross-role access

**[AWS](https://daily.dev/sources/aws)** · 2 min read · 1 upvotes · 0 comments

## Summary

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.
