AWS Partner Central agents MCP Server now supports OAuth with AWS Sign-In

AWS partners can now access AWS Partner Central agents from tools they already use, such as Amazon Quick and Kiro, using OAuth through AWS Sign-In. Partners can authorize agent access with their existing AWS identities, sign-in methods, IAM permissions, and governance controls without installing or maintaining additional authentication software. Previously, AWS Partners needed to set up an MCP proxy with SigV4 credentials to access Partner Central agents from their existing tools, or sign in to AWS Partner Central through the AWS Management Console with IAM credentials.
