Why warden_start_svc needs a policy

Starting system services is an Execute action because it runs external operations whose effects depend on which services are started and what those services subsequently do. While not inherently destructive (the operation is reversible via stop commands), it triggers external processes and changes system state.

From the tool's definition The tool name 'warden_start_svc' and description 'Start Warden system services' indicate execution of infrastructure/system operations that trigger external processes (starting services).

POLICY

How to control warden_start_svc

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_start_svc:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "warden_start_svc": {
      "limits": [
        {
          "counter": "warden_start_svc_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

warden_start_svc stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. 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.
