Why cdk_best_practices needs a policy

With no description available, we can only infer from the name. 'cdk_best_practices' likely reads/retrieves best practice recommendations for AWS CDK, which would be a Read operation. However, given the very low confidence from an empty description, and that it appears to be an informational/advisory tool rather than one that directly reads user data or modifies anything, Other is appropriate.

From the tool's definition Tool description is empty and uninformative; the tool name 'cdk_best_practices' suggests it may return guidance or recommendations about CDK best practices.

POLICY

How to control cdk_best_practices

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 cdk_best_practices:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "cdk_best_practices": {
      "limits": [
        {
          "counter": "cdk_best_practices_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

cdk_best_practices gets a rate cap, and 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.
