AWS appstream2: Add MCP endpoints for four new agent access Regions

Service: appstream2 · 2026-10-11 · Documentation medium

File: appstream2/latest/developerguide/allowed-domains.md · Type: network

Summary

Adds agentaccess-mcp endpoint hostnames for Asia Pacific (Malaysia), Europe (Milan), Europe (Spain), and South America (São Paulo) to the allowed-domains/MCP endpoints table.

Security assessment

The table feeds firewall/proxy allowlists for the MCP service, so the change is network-configuration relevant, but it only extends an existing list of AWS-owned endpoints to new Regions and does not address any weakness.
