THE RISK

Critical Risk

Why deposit needs a policy

Deposits move money into accounts and constitute financial transactions that cannot be easily reversed without explicit withdrawal operations. This is a classic Financial category tool with high severity due to potential for unauthorized account transfers if an AI agent were compromised or given incorrect instructions.

From the tool's definition Tool description states 'Deposit money into a savings account', which involves moving money and committing financial obligations. Server context confirms this is a Core Banking Solution for Financial Institutions managing financial transactions.

Documented attack patterns abuse exactly the kind of access deposit gives an agent:

POLICY

How to control deposit

PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Mifosx, and nothing reaches the server without passing your rules. This is the rule we recommend for deposit:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "deposit": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to deposit is blocked until a human approves it. The rest of the server keeps working.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
