## Why list_tags_for_resource is rated Low

This tool queries and retrieves existing tag metadata associated with AWS resources. It performs no write, delete, or execution operations—purely informational retrieval. The blast radius of misuse is minimal since tags are typically non-sensitive metadata, and reading them poses no direct risk to system integrity or data security.

From the tool's own definition: "Tool name 'list_tags_for_resource' and description 'List tags for a resource' indicate a query operation that retrieves metadata without modification or side effects."

## Use case

AI agents call list_tags_for_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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches AWS:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_tags_for_resource": {}
  }
}
