AI agents use liara_add_domain 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.
This tool modifies application configuration by associating a domain with an app. While it creates a new resource binding, it is reversible and does not execute arbitrary code, delete data, or commit financial transactions. The blast radius is moderate—misconfiguration could redirect traffic or cause service unavailability, but the change can be undone.
From the tool's definition Tool name 'liara_add_domain' and description 'Add a domain to an app' indicate creation/modification of DNS/domain configuration for an application. The action is reversible (domain can be removed).
Documented attack patterns abuse exactly the kind of access liara_add_domain 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_add_domain:
{
"version": "1",
"default": "deny",
"tools": {
"liara_add_domain": {
"limits": [
{
"counter": "liara_add_domain_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}liara_add_domain 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.
Free to start. No card required.
Add a domain to an app. 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_add_domain: 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_add_domain 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_add_domain 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_add_domain. 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_add_domain 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.
