Why memory_update needs a policy

Without a description, we infer from context and naming. 'memory_update' most likely creates or modifies data (Write) rather than querying (Read) or executing arbitrary operations (Execute). The empty description and generic name prevent higher confidence.

From the tool's definition Tool name 'memory_update' suggests modifying stored state or data. Description is empty, limiting confidence.

Documented attack patterns abuse exactly the kind of access memory_update gives an agent:

How to control memory_update

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "memory_update": {
      "limits": [
        {
          "counter": "memory_update_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

memory_update stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
