Remove GRE tunnel
AI agents call mikrotik_remove_gre_tunnel 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.
Removing a GRE tunnel is a destructive operation that cannot be undone without manual reconfiguration. It deletes network infrastructure configuration, which fits the Destructive category (irreversibly deletes or overwrites data). The high severity reflects that tunnel removal could disrupt network connectivity and service delivery depending on the router's role and the tunnel's dependencies.
From the tool's definition Tool name contains 'remove' and description states 'Remove GRE tunnel', indicating irreversible deletion of network tunnel configuration.
Attacks that exploit this kind of access
Remove GRE tunnel. 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_gre_tunnel: 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_gre_tunnel 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_gre_tunnel 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_gre_tunnel. 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_gre_tunnel 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.
