create_service_gateway · OCI MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_service_gateway does on OCI MCP Server

AI agents use create_service_gateway to create or update resources in OCI MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your OCI MCP Server environment.

WHY IT NEEDS A POLICY

Why create_service_gateway needs a policy

This tool creates a new service gateway resource in Oracle Cloud Infrastructure, which is a reversible Write operation (the gateway can be deleted). However, the severity is elevated to 'high' because service gateways control network traffic flow to OCI services (object storage, databases, etc.) and misconfiguration by an AI agent could disrupt service availability or expose traffic patterns.

From the tool's definition Tool name is 'create_service_gateway' and description states 'Create a service gateway'. The verb 'create' indicates a Write operation that creates a new networked resource in OCI.
