AI agents use liara_detach_network to create or update resources in Liara MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Liara MCP Server environment.
Detaching a network from a VM modifies the VM's network configuration by removing a network association. This is a reversible write operation (the network can be re-attached), but it has high severity because it can cause network connectivity loss for the VM, potentially taking services offline or disrupting running workloads.

Documented attack patterns abuse exactly the kind of access liara_detach_network gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Liara MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for liara_detach_network:
{
"version": "1",
"default": "deny",
"tools": {
"liara_detach_network": {
"limits": [
{
"counter": "liara_detach_network_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}liara_detach_network stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Detach a network from a VM. It is categorised as a Write tool in the Liara MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Liara MCP Server MCP server in PolicyLayer and add a rule for liara_detach_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 Liara MCP Server. Nothing to install.
liara_detach_network 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 liara_detach_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.
Set action: deny in the PolicyLayer policy for liara_detach_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.
liara_detach_network is provided by the Liara MCP Server MCP server (razavioo/liara-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Liara MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
