What authenticate_slack_workspace does on Apple Shortcuts

AI agents call authenticate_slack_workspace as a supporting operation in Apple Shortcuts workflows.

Why authenticate_slack_workspace needs a policy

This tool performs authentication/authorization (OAuth flow or similar) to connect a Slack workspace. It doesn't read data, write data, execute code, destroy data, or move money — it establishes a credential/session link. The description is incomplete (truncated), which lowers confidence. The closest category is Other since authentication setup is a configuration/identity operation.

POLICY

How to control authenticate_slack_workspace

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_slack_workspace:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "authenticate_slack_workspace": {
      "limits": [
        {
          "counter": "authenticate_slack_workspace_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

authenticate_slack_workspace gets a rate cap, and 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.
