Removes a firewall filter rule from MikroTik device
AI agents call mikrotik_remove_filter_rule to permanently remove resources in MikroTik MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes firewall rules, which is an irreversible action. While not as immediately catastrophic as deleting user data, removing firewall rules can disable critical security controls, expose the network to threats, or break existing security policies. The action cannot be undone through normal operation and requires either manual reconfiguration or backup restoration.
From the tool's definition Removes a firewall filter rule from MikroTik device. The verb 'removes' combined with 'firewall filter rule' indicates irreversible deletion of network security configuration.

Register the MikroTik MCP server in PolicyLayer and add a rule for mikrotik_remove_filter_rule: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MikroTik MCP. Nothing to install.
mikrotik_remove_filter_rule is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the mikrotik_remove_filter_rule rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
