create_security_list · OCI MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_security_list does on OCI MCP Server

AI agents use create_security_list 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_security_list needs a policy

This tool creates a new security list (OCI's network access control resource), which is a reversible write operation that modifies cloud infrastructure. It does not delete data (ruling out Destructive), does not move money (not Financial), and does not execute arbitrary code (not Execute).

From the tool's definition Tool name 'create_security_list' and description 'Create a security list' indicate creation of a network security resource. The mention of 'ingress_tcp_ports defaults to [22, 80, 443]' confirms this modifies firewall/access control configuration.

create_security_list Rate-limited
