POLICY

How to control get_fina_indicator

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

policy.json

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

get_fina_indicator 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 A Share — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
