WHAT IT DOES

What create_broker does on Amazon Location Service MCP Server

AI agents use create_broker to create or update resources in Amazon Location Service MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Amazon Location Service MCP Server environment.

THE RISK

Medium Risk

Why create_broker needs a policy

The 'create_' prefix strongly suggests this tool creates or initializes a new broker resource, which would be a reversible write operation. Without a detailed description, exact scope cannot be determined, but reversible creation is lower risk than destructive deletion. Classified as Write rather than Execute because 'create' typically manifests data changes, not external code execution or side effects.

From the tool's definition Tool name 'create_broker' with 'create' prefix indicates data creation capability. Description is empty, limiting precision. Context is AWS Location Service, where brokers manage resource configurations.

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

POLICY

How to control create_broker

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 create_broker:

policy.json

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

create_broker 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.
