WHAT IT DOES

What hash_random_field does on Amazon Location Service MCP Server

AI agents call hash_random_field to retrieve information from Amazon Location Service MCP Server 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 hash_random_field needs a policy

This tool retrieves random field(s) from an existing hash—a read-only query operation. There is no indication it modifies data, executes code, deletes anything, or initiates financial transactions. The word 'Get' confirms data retrieval. The blast radius if misused by an AI agent is minimal: it only exposes whatever data is already in the hash.

From the tool's definition Tool name 'hash_random_field' and description 'Get random field(s) from hash' indicate a retrieval operation that reads data from a hash data structure without modification or side effects.

POLICY

How to control hash_random_field

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

policy.json

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

hash_random_field is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
