MOST DANGEROUS TOOLS

Critical Risk

The most dangerous Finance App tools

Financial · High transfer_between_accounts This tool moves money between accounts, which commits financial obligations and transfers value. Destructive · High delete_budget This tool permanently removes budget records from the accounting system without the ability to undo the action. Destructive · High archive_account Archiving an account is effectively irreversible in accounting systems — it removes the account from active use and cannot be easily undone without administrative intervention. Write · Medium delete_transaction Despite being named 'delete', this tool works by creating a reversing/offsetting transaction — a standard double-entry accounting technique.

11 of Finance App's 22 tools can modify, destroy, or commit something on every call — and an agent calls them with no built-in limits.

POLICY

How to control Finance App

PolicyLayer is an MCP gateway — it sits between your AI agents and Finance App, and nothing reaches the server without passing your rules. These are the rules we recommend:

Block financial tools by default

{
  "transfer_between_accounts": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Requires human approval."
      }
    ]
  }
}

Financial tools should be explicitly enabled per use case, not open by default.

Deny destructive operations

{
  "archive_account": {
    "deny_if": [
      {
        "conditions": [],
        "on_deny": "Blocked by default. Requires approval."
      }
    ]
  }
}

Destructive tools should never be available to autonomous agents without human approval.

Rate limit write operations

{
  "create_account": {
    "limits": [
      {
        "counter": "create_account_per_hour",
        "window": "hour",
        "max": 30,
        "scope": "grant"
      }
    ]
  }
}

Prevents bulk unintended modifications from agents caught in loops.

Cap read operations

{
  "get_account_balance": {
    "limits": [
      {
        "counter": "get_account_balance_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

Can an AI agent delete data through the Finance App MCP server? +

Yes. The Finance App server exposes 2 destructive tools including archive_account, delete_budget. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.

How do I prevent bulk modifications through Finance App? +

The Finance App server has 8 write tools including create_account, create_budget, delete_transaction.
