Removes a DHCPv6 lease
AI agents call mikrotik_remove_dhcpv6_lease to permanently remove resources in MikroTik Cursor MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes DHCP lease data from the router, which cannot be undone. Unauthorized removal of leases could disrupt network connectivity for devices and disrupt service availability. While not financial, it has significant operational impact and is clearly destructive in nature, making it more severe than Write operations.
From the tool's definition Tool name explicitly states 'remove' combined with 'DHCPv6 lease'; description confirms it 'Removes a DHCPv6 lease'. Removal of lease records is irreversible deletion of network configuration state.
Attacks that exploit this kind of access
Removes a DHCPv6 lease. It is categorised as a Destructive tool in the MikroTik Cursor MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MikroTik Cursor MCP server in PolicyLayer and add a rule for mikrotik_remove_dhcpv6_lease: 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 Cursor MCP. Nothing to install.
mikrotik_remove_dhcpv6_lease 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_dhcpv6_lease 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.
Set action: deny in the PolicyLayer policy for mikrotik_remove_dhcpv6_lease. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
mikrotik_remove_dhcpv6_lease is provided by the MikroTik Cursor MCP server (kevinpez/mikrotik-cursor-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
