Delete a stored customer bank account (DELETE /customers/{customer_id}/bankaccounts/{id}).
AI agents call delete_bank_account to permanently remove resources in Mcp Ap2 — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes customer bank account information, which cannot be undone and has severe implications for payment processing, customer service recovery, and potential regulatory compliance issues. The irreversible nature and financial context make this Destructive (highest severity) rather than Financial, as the primary action is deletion rather than money movement.
From the tool's definition Tool name explicitly uses 'delete'; description specifies 'Delete a stored customer bank account' with DELETE HTTP method, indicating irreversible removal of financial account data.
Documented attack patterns abuse exactly the kind of access delete_bank_account gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Ap2, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_bank_account:
{
"version": "1",
"default": "deny",
"hide": [
"delete_bank_account"
]
}delete_bank_account disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
