THE RISK

Low Risk

Why getInsightTypes needs a policy

This tool performs a straightforward data retrieval operation—fetching a list or summary of insight types from the Robotoff system. It has no side effects, does not execute external code, does not modify data, and does not involve financial transactions. The blast radius of misuse is minimal, as an AI agent could only retrieve information about what insight types exist, which poses no security or operational risk.

From the tool's definition Tool name 'getInsightTypes' and description 'Get a summary of available AI insight types' indicate a query operation that retrieves metadata about available insights without modifying, executing, or deleting any data.

POLICY

How to control getInsightTypes

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

policy.json

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

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