AI agents call remove-broadcast to permanently remove resources in Email Sending MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently deletes a broadcast communication that has likely been set up and potentially sent. The irreversible deletion of marketing/broadcast content constitutes a destructive operation that cannot be undone. While the tool includes safety measures (requiring explicit user confirmation), the underlying capability is destructive.
From the tool's definition Tool description states 'Remove a broadcast by ID' and 'warn the user that removing a broadcast is irreversible'. The irreversible nature and explicit mention of irreversibility directly indicates destructive action.
Documented attack patterns abuse exactly the kind of access remove-broadcast gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Email Sending MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for remove-broadcast:
{
"version": "1",
"default": "deny",
"hide": [
"remove-broadcast"
]
}remove-broadcast disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
