Why search_cdk_documentation needs a policy

A documentation search operation is a read-only retrieval task with no capability to modify, delete, or execute code. Even if it could be misused to extract sensitive information from documentation, the blast radius is limited to information disclosure rather than system compromise or data modification.

From the tool's definition Tool name 'search_cdk_documentation' indicates a documentation search function. The description is empty, but the name and context (Amazon EKS/AWS Labs MCP server with CDK analysis tools) strongly suggest this retrieves documentation content without side…

POLICY

How to control search_cdk_documentation

PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon EKS MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for search_cdk_documentation:

policy.json

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

search_cdk_documentation 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 EKS 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.
