WHAT IT DOES

What publish_theme does on Shopify Graphql

AI agents use publish_theme to create or update resources in Shopify Graphql, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Shopify Graphql environment.

RISK

Why publish_theme is rated Medium

Publishing a theme changes the active/live theme on the Shopify storefront, which is a significant write operation affecting the public-facing store. While technically reversible by switching back to another theme, it immediately impacts the live store experience for all visitors. It does not delete data, execute arbitrary code, or involve financial transactions.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs publish_theme safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Shopify Graphql, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For publish_theme, this is the rule to start with:

publish_theme Rate-limited

publish_theme stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

{
  "version": "1",
  "default": "deny",
  "tools": {
    "publish_theme": {
      "limits": [
        {
          "counter": "publish_theme_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Shopify Graphql, apply this rule, and every publish_theme call is checked against it from then on.
