Why get_earnings needs a policy

From the tool's definition Tool name is 'get_earnings' and description states 'Fetch earnings data' — both indicate data retrieval. No language suggesting modifications, deletions, or financial transactions.

How to control get_earnings

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_earnings": {}
  }
}

get_earnings is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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