THE RISK

Low Risk

Why setup_check needs a policy

The tool checks configuration prerequisites without modifying any state. It retrieves and validates existing configuration, making it a read-only operation with minimal risk.

From the tool's definition 'Check if AWS Security Agent prerequisites are configured' — purely a read/diagnostic operation

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

POLICY

How to control setup_check

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Redshift MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for setup_check:

policy.json

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

setup_check is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Amazon Redshift MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
