Save your Runway API key. Call this when the user provides their key.
AI agents use configure_runway_api_key to create or update resources in Apple Shortcuts — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Apple Shortcuts environment.
This tool creates or modifies stored API key data, which is a reversible write operation. While it doesn't delete data (not Destructive) or execute code directly (not Execute), it does alter system state by persisting credentials. The severity is high because misconfigured or malicious API key storage could compromise security, enable unauthorized API access, or be used to access external services fraudulently.
From the tool's definition 'Save your Runway API key' indicates persistent storage of credentials; this modifies application state by writing authentication material to configuration/storage.
Documented attack patterns abuse exactly the kind of access configure_runway_api_key gives an agent:
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_runway_api_key:
{
"version": "1",
"default": "deny",
"tools": {
"configure_runway_api_key": {
"limits": [
{
"counter": "configure_runway_api_key_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}configure_runway_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.

Save your Runway API key. Call this when the user provides their key. It is categorised as a Write tool in the Apple Shortcuts MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Apple Shortcuts MCP server in PolicyLayer and add a rule for configure_runway_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.
configure_runway_api_key is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the configure_runway_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.
Set action: deny in the PolicyLayer policy for configure_runway_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.
configure_runway_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.
Start from Apple Shortcuts, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
