Send yourself a Slack note that actually notifies you. This sends a direct message from the Slack app to you, so Slack treats it as a real notification. It is separate from your own self-DM
AI agents use send_myself_a_note 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 a new Slack message (a write operation) but does not execute arbitrary code, delete data, or affect external systems beyond creating a notification. The action is reversible (the message can be deleted), has minimal blast radius, and only affects the user's own notifications.
From the tool's definition Tool description states it 'Send yourself a Slack note that actually notifies you' and 'sends a direct message from the Slack app to you'. These are write operations that create a new message/notification without modifying existing data irreversibly.
Documented attack patterns abuse exactly the kind of access send_myself_a_note 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 send_myself_a_note:
{
"version": "1",
"default": "deny",
"tools": {
"send_myself_a_note": {
"limits": [
{
"counter": "send_myself_a_note_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}send_myself_a_note 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.

Send yourself a Slack note that actually notifies you. This sends a direct message from the Slack app to you, so Slack treats it as a real notification. It is separate from your own self-DM. 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 send_myself_a_note: 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.
send_myself_a_note 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 send_myself_a_note 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 send_myself_a_note. 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.
send_myself_a_note 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.
