Why record_journal_entry needs a policy

This is a core financial operation that cannot be trivially undone and has direct financial implications for the institution and its clients.

POLICY

How to control record_journal_entry

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 record_journal_entry:

policy.json

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

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