WHAT IT DOES

What list_terminologies does on AWS

RISK

Why list_terminologies is rated Low

This tool queries and returns metadata about existing terminologies without modifying, deleting, or executing any operations. It is a straightforward read/list operation typical of AWS translation or terminology service management, posing minimal risk even if invoked by an AI agent with incorrect parameters.

From the tool's definition Tool name 'list_terminologies' combined with description 'List all available custom terminologies. Returns a list of terminologies with their metadata and language pairs.' indicates a retrieval operation with no side effects.

RECOMMENDED RULE

The rule that runs list_terminologies safely

PolicyLayer is an MCP gateway: it sits between your AI agents and AWS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For list_terminologies, this is the rule to start with:

list_terminologies Allowed

list_terminologies is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "list_terminologies": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect AWS, apply this rule, and every list_terminologies call is checked against it from then on.
