THE RISK

Why connect-jump-host-serverless-cache needs a policy

The tool name suggests it establishes a network connection (likely SSH tunnel or proxy) through a jump host to access a serverless cache (e.g., ElastiCache Serverless). This implies execution of network/connection operations. However, the description is empty, which significantly lowers confidence.

From the tool's definition Tool name: 'connect-jump-host-serverless-cache' — implies establishing a network connection through a jump host to a serverless cache resource

POLICY

How to control connect-jump-host-serverless-cache

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 connect-jump-host-serverless-cache:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "connect-jump-host-serverless-cache": {
      "limits": [
        {
          "counter": "connect-jump-host-serverless-cache_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

connect-jump-host-serverless-cache stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. 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.
