THE RISK

Why rec-details needs a policy

This tool retrieves recommendation details by querying and aggregating data from multiple AWS services. It performs no mutations, executions, or destructive operations. However, the medium severity reflects that the aggregated recommendation data could expose sensitive architectural, security, or operational information about AWS infrastructure and applications, which could be valuable to an attacker for planning…

From the tool's definition Tool name 'rec-details' and description 'Get enhanced recommendation details with integrated data from multiple AWS services' indicate data retrieval only. The verb 'Get' and 'retrieval' pattern align with Read operations.

POLICY

How to control rec-details

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "rec-details": {}
  }
}

rec-details 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 ECS 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.
