WHAT IT DOES

What dev-theme-list does on Magento 2 Development MCP Server

THE RISK

Low Risk

Why dev-theme-list needs a policy

This tool performs a simple query/list operation to enumerate existing themes in a Magento 2 development environment. It retrieves information without modifying, executing code, deleting data, or affecting system state. The blast radius is minimal—an agent misusing this tool could only gather information about available themes, which is non-sensitive metadata in a development context.

From the tool's definition Tool name 'dev-theme-list' and description 'List all available Magento 2 themes' indicate a retrieval operation with no data modification or side effects.

POLICY

How to control dev-theme-list

PolicyLayer is an MCP gateway — it sits between your AI agents and Magento 2 Development MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for dev-theme-list:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "dev-theme-list": {}
  }
}

dev-theme-list is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
