Why get_model_info needs a policy

This tool queries and returns information about a model without modifying, deleting, or executing anything. It is a straightforward read operation with minimal security impact even if misused by an AI agent.

From the tool's definition Tool name 'get_model_info' and description 'Get detailed information about a specific model' indicate a retrieval operation with no side effects.

POLICY

How to control get_model_info

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

policy.json

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

get_model_info 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 vLLM MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
