WHAT IT DOES

What get_datastore does on AWS

AI agents call get_datastore 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_datastore is rated Low

This tool retrieves or queries information about a datastore without creating, modifying, or deleting anything. It has no side effects beyond returning existing data. The sibling tools include write operations (append_rows_to_table, attach_group_policy) and destructive actions (implied by audit and analyze functions), but get_datastore itself is purely informational.

From the tool's definition Tool name 'get_datastore' and description 'Get information about a specific data store' indicate a retrieval operation with no modification or deletion. The verb 'get' is a classic read pattern.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

get_datastore Allowed

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

policy.json

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

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_datastore call is checked against it from then on.
