Why list_images needs a policy

This tool performs a retrieval operation with filtering and pagination capabilities. It queries and returns container image information from the RAD Security system without creating, modifying, deleting, or executing any operations. The parameters (page, page size, sort, search) are all used for refining query results, which is characteristic of a Read category tool.

From the tool's definition Tool name 'list_images' and description 'List container images with optional filtering by page, page size, sort, and search query' indicate a read-only query operation that retrieves container image data without modification, deletion, or execution.

How to control list_images

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

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

list_images 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 RAD Security — 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.
