THE RISK

Low Risk

Why describe_support_cases needs a policy

The tool name suggests it retrieves or queries AWS support case data with no side effects. Empty description reduces confidence slightly, but the naming convention strongly indicates a Read operation. Support case data is typically informational and non-sensitive in terms of operational risk, justifying 'low' severity.

From the tool's definition Tool name 'describe_support_cases' indicates a query/retrieval operation that lists or fetches support case information. The verb 'describe' typically retrieves data without modification.

POLICY

How to control describe_support_cases

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 describe_support_cases:

policy.json

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

describe_support_cases 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.
