Why create_group_loan_app needs a policy

This tool creates (writes) a new loan application record, which is a reversible action—the application can be updated, rejected, or withdrawn. However, it operates within a financial institution's core banking system (Mifos X) and initiates a financial obligation workflow.

From the tool's definition Tool creates a new group loan application (explicit 'create' action); description states it 'Create[s] a group loan application'. This is a write operation that establishes a new financial record in a core banking system.

POLICY

How to control create_group_loan_app

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 create_group_loan_app:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_group_loan_app": {
      "limits": [
        {
          "counter": "create_group_loan_app_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_group_loan_app stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Mcp Mifosx — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
