Why list_move needs a policy

Moving an element from one list to another modifies data in two locations (removes from source, adds to destination), which is a reversible write/update operation. However, the description is vague and doesn't specify what kind of 'lists' or 'elements' are involved in the context of Amazon Location Service.

From the tool's definition "Move element from one list to another"

Documented attack patterns abuse exactly the kind of access list_move gives an agent:

How to control list_move

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 list_move:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_move": {
      "limits": [
        {
          "counter": "list_move_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

list_move 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.
