THE RISK

Low Risk

Why get_units needs a policy

This tool retrieves or queries unit data (likely measurement units used in recipes like cups, grams, etc.). It performs no modifications, deletions, or external operations. It falls squarely into the Read category as a simple data retrieval function. The severity is low because misuse would only expose reference data with no blast radius or impact on actual recipes, meal plans, or shopping lists.

From the tool's definition Tool name is 'get_units' and description states 'List or search for units.' This is a retrieval operation with no side effects.

POLICY

How to control get_units

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

policy.json

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

get_units 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 Tandoor 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.
