WHAT IT DOES

What get_resource does on AWS

AI agents call get_resource to retrieve information from AWS without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_resource is rated Low

The name 'get_resource' indicates a query/retrieval action typical of Read category. However, the empty description and lack of parameter details create uncertainty about what 'resource' means in an AWS context—it could theoretically access sensitive data like credentials, keys, or configurations.

From the tool's definition Tool name 'get_resource' strongly suggests a retrieval operation with no side effects. Description is empty, limiting confidence.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs get_resource 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 get_resource, this is the rule to start with:

get_resource Allowed

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

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_resource": {}
  }
}

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 get_resource call is checked against it from then on.
