THE RISK

Why get_terminology needs a policy

This tool retrieves or queries information about a terminology resource. It performs a simple lookup operation with no side effects, data modification, code execution, or destructive actions. The verb 'Get' confirms read-only semantics. Severity is low as misuse would only expose existing data without enabling further harmful operations.

From the tool's definition Tool name 'get_terminology' and description 'Get detailed information about a specific terminology' indicate a retrieval operation with no modification or execution of code.

POLICY

How to control get_terminology

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

policy.json

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

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