AI agents call delete_contact_list to permanently remove resources in Frontapp MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a contact list permanently removes data that cannot be undone. This is a destructive operation affecting potentially many contacts grouped in that list. The high severity reflects the irreversible nature and potential impact on business operations and customer relationship data, though the blast radius is somewhat limited to a single list rather than entire contact databases.
From the tool's definition Tool named 'delete_contact_list' with description 'Delete a contact list'. The verb 'delete' indicates irreversible removal of data.
Documented attack patterns abuse exactly the kind of access delete_contact_list gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Frontapp MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_contact_list:
{
"version": "1",
"default": "deny",
"hide": [
"delete_contact_list"
]
}delete_contact_list disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
