Why list_journal_entries needs a policy

This tool retrieves and queries financial journal entries from the core banking system. While the server handles sensitive financial data, the tool itself is a read-only operation that queries existing records. The blast radius of misuse is limited to information disclosure rather than unauthorized financial transactions, data modification, or deletion.

From the tool's definition Tool name is 'list_journal_entries' and description states it 'List journal entries for an account or transaction ID'. The verb 'list' indicates retrieval of existing data without modification, creation, or deletion.

POLICY

How to control list_journal_entries

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 list_journal_entries:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_journal_entries": {}
  }
}

list_journal_entries is read-only, so it stays allowed — but 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.
