Why config-show needs a policy

This tool only views or retrieves configuration values with no side effects. It performs a query/fetch operation typical of Read category tools. The verb 'view' and the absence of any modification language confirm read-only behavior.

From the tool's definition Tool name 'config-show' and description 'View Magento 2 system configuration values' indicate a read-only operation that retrieves configuration data without modification.

POLICY

How to control config-show

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 config-show:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "config-show": {}
  }
}

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