Disables VLAN filtering on a bridge
AI agents use mikrotik_disable_bridge_vlan_filtering to create or update resources in MikroTik Cursor MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MikroTik Cursor MCP environment.
This tool modifies network infrastructure by changing bridge VLAN filtering settings. While the change is technically reversible (filtering can be re-enabled), disabling VLAN filtering has significant blast radius: it can expose network segments that were previously isolated, potentially allowing unintended traffic flows, security breaches, and lateral network movement.
From the tool's definition The tool disables VLAN filtering on a bridge, which modifies network configuration. The verb 'disables' indicates a configuration change that alters the bridge's behavior—specifically turning off VLAN filtering, which is a reversible modification to the…
Attacks that exploit this kind of access
Disables VLAN filtering on a bridge. It is categorised as a Write tool in the MikroTik Cursor MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MikroTik Cursor MCP server in PolicyLayer and add a rule for mikrotik_disable_bridge_vlan_filtering: 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_disable_bridge_vlan_filtering is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the mikrotik_disable_bridge_vlan_filtering 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_disable_bridge_vlan_filtering. 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_disable_bridge_vlan_filtering 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.
