THE RISK

Low Risk

Why get_availability needs a policy

This tool retrieves and queries real-time inventory data from Alko stores with optional city filtering. It has no side effects—it does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal: an AI agent could only retrieve availability information, which poses no security, operational, or financial risk.

From the tool's definition Tool description states it 'Check[s] real-time product availability' and 'Returns store names with stock quantities.' The verbs 'check' and 'returns' indicate data retrieval.

POLICY

How to control get_availability

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

policy.json

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

get_availability 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 Alko 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.
