Why create_bare_metal_server needs a policy

Creating bare metal servers in a cloud provider is a reversible Write operation—new infrastructure can be provisioned and later deleted. However, it carries high severity because provisioning infrastructure typically incurs financial costs and creates multiple dependent systems (networking, DNS, databases).

From the tool's definition Tool name 'create_bare_metal_server' indicates creation of cloud infrastructure resources. Description is empty, but the verb 'create' and context within Vultr cloud management (which manages compute, networking, and billing) clearly indicates resource…

POLICY

How to control create_bare_metal_server

PolicyLayer is an MCP gateway — it sits between your AI agents and Vultr MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for create_bare_metal_server:

policy.json

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

create_bare_metal_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.

Create a free account and register Vultr MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
