AI agents call is_uae_holiday to retrieve information from MCP-Dubai without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

No data is created, modified, deleted, or used to trigger external actions. The blast radius of misuse is negligible—an incorrect holiday check cannot cause harm to systems or data.
