THE RISK

Why get_secret needs a policy

This tool retrieves game secret information for dungeon master viewing purposes. While it provides comprehensive information ('shows all info'), it performs no modification, deletion, or execution of code. The operation is read-only data retrieval within the RPG game state management context. The 'DM view' qualifier confirms this is informational access for game administration purposes, not a state-altering action.

From the tool's definition Tool name 'get_secret' with description 'Get a secret by ID (DM view - shows all info)' indicates retrieval of data without modification. The verb 'Get' and the context of fetching information by ID are characteristic of read operations.

POLICY

How to control get_secret

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

policy.json

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

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