  "jsonrpc": "2.0",

## Why create_subdomain is rated Medium

Creating a subdomain is a Write operation—it creates new DNS configuration entries and domain structures that can be reversed by deletion. While it has significant blast radius in a hosting environment (an agent could create unwanted subdomains, potentially interfering with services or DNS resolution), it is reversible and does not meet the threshold of Destructive (which would require irreversible…

From the tool's own definition: "Tool name 'create_subdomain' and description 'Create a new subdomain' indicate the creation of a new DNS subdomain configuration."

## Use case

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

## Recommended policy (PolicyLayer)
