THE RISK

Low Risk

Why get_template_variables needs a policy

This is a read-only operation that queries template metadata to inform users which variables must be populated. It has no side effects, does not execute code or trigger external operations, does not modify data, and does not involve financial transactions. The blast radius of misuse is minimal—worst case, an agent learns which variables a template expects, which is informational only.

From the tool's definition Tool name 'get_template_variables' and description 'Show which variables are required to render a template' indicate a query operation that retrieves metadata about template structure without modifying, executing, or deleting anything.

POLICY

How to control get_template_variables

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

policy.json

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

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