cloudflare_delete_ruleset_rule
AI agents call cloudflare_delete_ruleset_rule to permanently remove resources in Cloudflare WAF MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool deletes WAF rules, which are security configurations that cannot be undone without recreation. Deletion of active WAF rules could disable critical security protections, expose zones to attacks, and cause operational disruption. This qualifies as Destructive (irreversible modification of configuration state) rather than Execute, as the primary action is removal of data/rules, not code execution.
