THE RISK

Low Risk

Why hash_random_field_with_values needs a policy

This tool retrieves (reads) random field-value pairs from a hash data structure. It performs a query operation with no capacity to modify, delete, or execute external logic. The blast radius of misuse is minimal—an agent could only read arbitrary hash fields, which poses low risk in isolation.

From the tool's definition 'Get random field(s) with their values from hash' — the verb 'Get' and lack of modification language indicate retrieval only. No side effects are described.

POLICY

How to control hash_random_field_with_values

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

policy.json

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

hash_random_field_with_values 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 Amazon Translate 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.
