THE RISK

Medium Risk

Why configure_gamma_api_key needs a policy

This tool modifies configuration state by setting an API key, which is a reversible write operation. However, the severity is high because a misconfigured or maliciously set API key could redirect subsequent Gamma API calls to attacker-controlled endpoints or cause authentication failures. The tool itself does not execute external operations or delete data, placing it in Write rather than Execute or Destructive.

From the tool's definition Tool name 'configure_gamma_api_key' and description 'Configure the Gamma API key for this session' indicate persistent modification of session state/configuration.

POLICY

How to control configure_gamma_api_key

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 configure_gamma_api_key:

policy.json

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

configure_gamma_api_key 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.

Questions about configure_gamma_api_key

What does the configure_gamma_api_key tool do? +

How do I enforce a policy on configure_gamma_api_key? +

Register the Apple Shortcuts MCP server in PolicyLayer and add a rule for configure_gamma_api_key: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Apple Shortcuts. Nothing to install.

What risk level is configure_gamma_api_key? +

configure_gamma_api_key is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit configure_gamma_api_key? +

Yes. Add a rate_limit block to the configure_gamma_api_key rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block configure_gamma_api_key completely? +

Set action: deny in the PolicyLayer policy for configure_gamma_api_key. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides configure_gamma_api_key? +

configure_gamma_api_key is provided by the Apple Shortcuts MCP server (@mindstone/mcp-server-apple-shortcuts). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Apple Shortcuts tool call.

Start from Apple Shortcuts, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
