mikrotik_create_vlan_interface · MikroTik MCP: Risk & Policy

WHAT IT DOES

What mikrotik_create_vlan_interface does on MikroTik MCP

AI agents use mikrotik_create_vlan_interface to create or update resources in MikroTik MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MikroTik MCP environment.

WHY IT NEEDS A POLICY

Why mikrotik_create_vlan_interface needs a policy

The tool creates a new VLAN interface, which is a Write operation (creates/modifies data reversibly). Severity is high because misconfiguration could disrupt network connectivity for multiple users, and a compromised AI agent could create unauthorized VLANs to segment networks maliciously or isolate critical systems.

From the tool's definition Tool name 'mikrotik_create_vlan_interface' and description 'Creates a VLAN interface on MikroTik device' indicate the tool creates (modifies) network configuration by adding a new VLAN interface.

FAQ

Questions about mikrotik_create_vlan_interface

What does the mikrotik_create_vlan_interface tool do? +

Creates a VLAN interface on MikroTik device. It is categorised as a Write tool in the MikroTik MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on mikrotik_create_vlan_interface? +

Register the MikroTik MCP server in PolicyLayer and add a rule for mikrotik_create_vlan_interface: 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.

What risk level is mikrotik_create_vlan_interface? +

Can I rate-limit mikrotik_create_vlan_interface? +

Yes. Add a rate_limit block to the mikrotik_create_vlan_interface 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.

How do I block mikrotik_create_vlan_interface completely? +

Set action: deny in the PolicyLayer policy for mikrotik_create_vlan_interface. 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.

What MCP server provides mikrotik_create_vlan_interface? +

mikrotik_create_vlan_interface is provided by the MikroTik MCP server (tarcisiodier/mcp-mikrotik). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
