WHAT IT DOES

What cdk_best_practices does on Amazon Bedrock Knowledge Base Retrieval MCP Server

AI agents call cdk_best_practices to retrieve information from Amazon Bedrock Knowledge Base Retrieval MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why cdk_best_practices needs a policy

The name implies a lookup or retrieval of best practices guidance, consistent with a Read operation. No modification, execution, deletion, or financial activity is indicated. However, the empty description significantly reduces confidence in this classification—the tool could potentially execute analysis or other operations not apparent from the name alone.

From the tool's definition Tool name 'cdk_best_practices' suggests querying or retrieving AWS CDK best practices information. The description is empty, limiting certainty.

POLICY

How to control cdk_best_practices

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Bedrock Knowledge Base Retrieval 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": {}
  }
}

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