THE RISK

Low Risk

Why analyzeProduct needs a policy

The tool queries the OpenFoodFacts database to retrieve nutritional information and applies AI analysis to present it; this is a read operation that retrieves data. There is no indication the tool creates, modifies, deletes, or executes arbitrary code. The low severity reflects minimal blast radius—misuse would only surface incorrect nutritional analysis, not compromise data integrity or trigger unintended actions.

From the tool's definition Tool description states 'Get AI nutritional analysis of a product' — retrieves and analyzes existing product data without modification, deletion, or execution of external operations. No side effects are described.

POLICY

How to control analyzeProduct

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 analyzeProduct:

policy.json

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

analyzeProduct 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.
