```json

## Why create_firewall_rule is rated Medium

Creating a firewall rule modifies the server's network security policy. While it is a reversible write operation (rules can be deleted), misconfiguration could expose services or block legitimate traffic, making the blast radius high. It does not execute code or irreversibly destroy data.

From the tool's own definition: "'Create firewall rule' — creates a new firewall rule, which is a write operation that modifies network access control configuration"

## Use case

AI agents use create_firewall_rule to create or update resources in 1Panel MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 1Panel MCP Server environment.
