THE RISK

Low Risk

Why gateway_list needs a policy

This tool performs a query/list operation to retrieve information about gateways (their status, version, type, and VNet settings). It has no capability to modify, delete, or execute actions on those gateways. The blast radius of misuse is minimal—an agent could discover gateway configurations but cannot change them or cause irreversible harm.

From the tool's definition Tool name 'gateway_list' and description 'List all gateways with their status, version, type, and VNet configuration' indicate a read-only operation that retrieves gateway metadata without modification or side effects.

POLICY

How to control gateway_list

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

policy.json

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

gateway_list 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 Force Fabric 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.
