Why authenticate_zendesk_account needs a policy

This tool establishes an authenticated connection/session by storing credentials (subdomain, API token). It creates or persists authentication state, which is a reversible write operation. It does not read data, execute commands, destroy data, or move money. Confidence is moderate because the description is truncated and full behavior is not entirely clear.

How to control authenticate_zendesk_account

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 authenticate_zendesk_account:

policy.json

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

authenticate_zendesk_account 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
