THE RISK

Low Risk

Why get_bare_metal_bandwidth needs a policy

This tool queries existing bandwidth metrics for a bare metal server. It retrieves data without creating, modifying, deleting, or executing operations. The blast radius of misuse is minimal—an agent could only enumerate bandwidth data already associated with accessible infrastructure, posing no direct operational risk.

From the tool's definition Tool name contains 'get' and description states 'Get bandwidth usage' — a retrieval operation with no modification or side effects.

POLICY

How to control get_bare_metal_bandwidth

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 get_bare_metal_bandwidth:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_bare_metal_bandwidth": {}
  }
}

get_bare_metal_bandwidth is read-only, so it stays allowed — but 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.
