cache_quit

THE RISK

Low Risk

Why cache_quit needs a policy

The tool closes a connection to a cache server, which is an internal housekeeping operation with no data modification, deletion, or external side effects. It does not create, modify, delete, or retrieve user data, nor does it execute code or move money. It appears out of place on an SNS/SQS server, which lowers confidence. Severity is low as misuse has minimal blast radius.

From the tool's definition 'Close the connection to the cache server' — this terminates a local/internal cache connection, not an SNS/SQS resource

POLICY

How to control cache_quit

PolicyLayer is an MCP gateway — it sits between your AI agents and Awslabs Amazon Sns Sqs, 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
