What unblock_ip does on cPanel MCP Server
AI agents use unblock_ip 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.
Why unblock_ip is rated Medium
This tool modifies security configuration by changing IP address blocklist state. It is reversible (can be re-blocked), so it is Write rather than Destructive. However, it has moderate security impact as improper unblocking could expose systems to malicious traffic or re-enable access for compromised IPs.
From the tool's definition Tool name 'unblock_ip' and description 'Unblock a previously blocked IP address' indicates modification of security firewall/blocklist rules. This reverses a prior block action, modifying the IP allowlist/blocklist state.

The rule that runs unblock_ip safely
PolicyLayer is an MCP gateway: it sits between your AI agents and cPanel MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For unblock_ip, this is the rule to start with:
unblock_ip stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect cPanel MCP Server, apply this rule, and every unblock_ip call is checked against it from then on.
