Why memory_create_event needs a policy

The 'create' verb indicates a Write operation that creates new data. Without a description, the actual scope and side effects cannot be fully determined, but event creation typically persists data reversibly.

From the tool's definition Tool name 'memory_create_event' suggests creation of an event record, a Write operation. Description is empty, limiting confidence.

POLICY

How to control memory_create_event

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 memory_create_event:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "memory_create_event": {
      "limits": [
        {
          "counter": "memory_create_event_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

memory_create_event stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
