WHAT IT DOES

What create_server does on Coolify

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

RISK

Why create_server is rated Medium

The tool creates/registers a new server resource (reversible operation via deletion). This is a Write action with high severity because provisioning servers impacts infrastructure configuration, costs, and system topology. It's not Destructive (not irreversible), not Financial (registration itself doesn't move money, though it may incur costs), and not Execute (doesn't run arbitrary code).

From the tool's definition Tool name and description explicitly state "Register a new server", which creates a new infrastructure resource in Coolify.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_server safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Coolify, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_server, this is the rule to start with:

create_server Rate-limited

create_server 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.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_server": {
      "limits": [
        {
          "counter": "create_server_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Coolify, apply this rule, and every create_server call is checked against it from then on.
