AI agents call delete_account to permanently remove resources in Telegram MCP Complete — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Account deletion is an irreversible operation that destroys all associated data and cannot be recovered. This meets the Destructive category criterion. Severity is high rather than critical because impact is scoped to a single account within the Telegram management system rather than affecting financial systems or multiple user accounts.
From the tool's definition Tool name 'delete_account' and description indicates account deletion (删除指定的账号 = 'delete specified account'). Explicitly states deletion cannot be undone for non-default accounts.
Documented attack patterns abuse exactly the kind of access delete_account gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Telegram MCP Complete, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_account:
{
"version": "1",
"default": "deny",
"hide": [
"delete_account"
]
}delete_account disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
