How to control ga_list_bigquery_links

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

policy.json

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

ga_list_bigquery_links 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 Apple Shortcuts — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
