Create a video entirely from a text description.
AI agents invoke generate_video_from_text to trigger actions in Apple Shortcuts. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool executes an Apple Shortcut that generates video content from text input. It triggers an external operation (media generation) whose effects depend on the text argument. It falls under Execute as it runs an action via the macOS shortcuts CLI. Severity is high because it could generate and store arbitrary video content, consume significant system resources, or be misused to produce harmful media.
From the tool's definition 'Create a video entirely from a text description' — triggers an external media generation operation via Apple Shortcuts CLI
Documented attack patterns abuse exactly the kind of access generate_video_from_text 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 generate_video_from_text:
{
"version": "1",
"default": "deny",
"tools": {
"generate_video_from_text": {
"limits": [
{
"counter": "generate_video_from_text_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
} generate_video_from_text stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a video entirely from a text description. It is categorised as a Execute tool in the Apple Shortcuts MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Apple Shortcuts MCP server in PolicyLayer and add a rule for generate_video_from_text: 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.
generate_video_from_text is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the generate_video_from_text 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 generate_video_from_text. 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.
generate_video_from_text 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.
