Why stream_info needs a policy

The tool retrieves or queries stream information with no indication of modification, execution, or deletion capabilities. It is purely informational, fitting the Read category. Severity is low because retrieving stream metadata typically has minimal blast radius even if misused—it would only expose information about existing streams.

From the tool's definition Tool name is 'stream_info' with description 'Get information about stream.' This is a retrieval operation that queries metadata about a stream without modification or side effects.

How to control stream_info

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 stream_info:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "stream_info": {}
  }
}

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

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