AI agents call cdk_best_practices to retrieve information from AWS without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves static informational content (best practices, guidelines, recommendations). It has no side effects, does not modify any data, and cannot cause harm if misused — it simply returns documentation/guidance text.
From the tool's definition Returns CDK best practices and security guidelines
Documented attack patterns abuse exactly the kind of access cdk_best_practices gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AWS, and nothing reaches the server without passing your rules. This is the rule we recommend for cdk_best_practices:
{
"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.

Register the AWS MCP server in PolicyLayer and add a rule for cdk_best_practices: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AWS. Nothing to install.
cdk_best_practices is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the cdk_best_practices rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for cdk_best_practices. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
cdk_best_practices is provided by the AWS MCP server (@awslabs/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from AWS, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
