WHAT IT DOES

What unifi_create_network does on UniFi Network MCP Server

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

WHY IT NEEDS A POLICY

Why unifi_create_network needs a policy

This tool creates new network infrastructure (VLANs/networks) which is a reversible modification operation. While it modifies critical network configuration, the action is not inherently destructive since VLANs can be deleted. The severity is high because misconfiguration or unintended network creation in a UniFi environment could disrupt network operations, isolate devices, or create security boundaries incorrectly.

From the tool's definition Tool name 'unifi_create_network' and description explicitly states 'Create a new VLAN/network'. The description notes 'not safe to retry — re-running creates duplicates', confirming it modifies network infrastructure by creating new resources.

FAQ

Questions about unifi_create_network

What does the unifi_create_network tool do? +

Create a new VLAN/network. management=GATEWAY means routed via UDM/UXG; SWITCH means VLAN-only; UNMANAGED means external. Idempotency: not safe to retry — re-running creates duplicates. It is categorised as a Write tool in the UniFi Network MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on unifi_create_network? +

Register the UniFi Network MCP Server MCP server in PolicyLayer and add a rule for unifi_create_network: 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 UniFi Network MCP Server. Nothing to install.

What risk level is unifi_create_network? +

unifi_create_network is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit unifi_create_network? +

Yes. Add a rate_limit block to the unifi_create_network 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 unifi_create_network completely? +

Set action: deny in the PolicyLayer policy for unifi_create_network. 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 unifi_create_network? +

unifi_create_network is provided by the UniFi Network MCP Server MCP server (owine/unifi-network-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
