THE RISK

Low Risk

Why get_server_info needs a policy

This tool purely retrieves and returns information about the server's exposed functionality and limitations. It has no side effects, performs no operations, and cannot affect data or system state. It is a straightforward informational query, placing it firmly in the Read category with low severity since misuse would only result in disclosure of already-known or low-sensitivity metadata about the server itself.

From the tool's definition Tool name 'get_server_info' and description 'Describe the currently exposed MCP surface and deferred areas' indicate a read-only query operation that retrieves metadata about the server's capabilities without modifying, executing, or deleting anything.

POLICY

How to control get_server_info

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_server_info:

policy.json

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

get_server_info 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.
