WHAT IT DOES

What list_stores does on TilbudsTrolden

AI agents call list_stores to retrieve information from TilbudsTrolden without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why list_stores needs a policy

This tool retrieves reference data (store directory information) without side effects. It returns a curated list of grocery chains and their identifiers for lookup purposes. There is no data modification, code execution, or irreversible action. The severity is low because misuse would only expose static store metadata with no blast radius to user data, finances, or system state.

From the tool's definition Tool description states it 'List[s] grocery chains with dealer IDs' and 'Returns store names and dealer IDs.' The function is explicitly for retrieval ('finding store IDs', 'seeing [a directory]'), with no modification, deletion, or external operation…

POLICY

How to control list_stores

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

policy.json

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

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