Why search_bare_metal_plans needs a policy

This tool queries and lists available bare metal server plans from Vultr's catalog. It retrieves product information to help users explore options but does not create, modify, delete, or execute infrastructure changes. The empty description reduces confidence slightly, but the function name is clear and unambiguous as a read-only search operation.

From the tool's definition Tool name 'search_bare_metal_plans' indicates a query/search operation returning information about Vultr bare metal hosting plans. The 'search' verb and 'plans' noun are consistent with data retrieval without modification.

POLICY

How to control search_bare_metal_plans

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 search_bare_metal_plans:

policy.json

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

search_bare_metal_plans 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.
