WHAT IT DOES

What policy_engine_create does on Amazon Location Service MCP Server

THE RISK

Medium Risk

Why policy_engine_create needs a policy

The 'create' verb classifies this as Write rather than Read or Execute. Given it's part of an AWS Location Service MCP server, it likely creates policies or policy-related resources, which are reversible via deletion. Severity is medium because policy misconfiguration could have moderate blast radius (access control impacts), but without detailed description, confidence is reduced to 0.60.

From the tool's definition Tool name is 'policy_engine_create' which uses the verb 'create' indicating a write operation that generates new resources. However, without a description, the exact scope and reversibility cannot be fully determined.

How to control policy_engine_create

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 policy_engine_create:

policy.json

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

policy_engine_create 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.
