AWS cli documentation change

Service: cli · 2026-05-22 · Documentation low

File: cli/latest/reference/devops-agent/list-services.md

Summary

Added 'mcpserversigv4' to the list of service types and included identical SigV4 MCP server documentation as in get-service.md, covering IAM role authentication and SigV4 signing parameters.

Security assessment

This mirrors the security documentation added in get-service.md, focusing on SigV4 authentication capabilities without indicating any security vulnerability fix. It expands documentation of security features but lacks evidence of addressing a specific issue.
