Delete a proxy host by ID
AI agents call delete_proxy_host to permanently remove resources in Nginx Proxy Manager MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a proxy host configuration, which cannot be undone without manual recreation. Deletion is irreversible, placing it in the Destructive category. Severity is high because misconfiguration or unauthorized use could disrupt web service routing for dependent applications, though it does not directly impact financial systems or data loss beyond the proxy configuration itself.
From the tool's definition Tool name 'delete_proxy_host' and description 'Delete a proxy host by ID' explicitly indicate irreversible deletion of proxy configuration data.
