WHAT IT DOES

What get_subnet does on OCI MCP Server

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

WHY IT NEEDS A POLICY
