AWS devopsagent medium security documentation change

Service: devopsagent · 2026-01-13 · Security-related medium

File: devopsagent/latest/userguide/configuring-capabilities-for-aws-devops-agent-connecting-mcp-servers.md

Summary

Added maximum tool length constraint (64 characters) and updated authentication credential update procedure requiring server deregistration/re-registration

Security assessment

The credential update procedure change enhances security by requiring complete credential rotation (deregister/reregister) instead of simple edits, reducing risks from stale credentials. The tool length limit prevents potential buffer overflow attacks.
