THE RISK

Low Risk

Why cache_quit needs a policy

This tool closes a cache server connection. It doesn't read, write, execute code, delete data, or move money — it terminates a network connection. This is a connection lifecycle management operation. The blast radius is low as it may disrupt caching but doesn't destroy data or trigger irreversible actions.

From the tool's definition Close the connection to the cache server.

POLICY

How to control cache_quit

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 cache_quit:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "cache_quit": {
      "limits": [
        {
          "counter": "cache_quit_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

cache_quit gets a rate cap, and 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.
