Why warden_list_environments needs a policy

This tool performs a read-only operation that queries and returns information about running environments. It has no side effects, does not modify data, execute code conditionally, delete resources, or commit financial transactions. The primary risk is information disclosure of environment names and paths, which is low severity in a development context.

From the tool's definition Tool name 'warden_list_environments' and description 'List all running Warden environments with their directories (returns structured JSON)' indicate a query operation that retrieves information without modifying state.

POLICY

How to control warden_list_environments

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

policy.json

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

warden_list_environments 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 Warden Magento 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.
