WHAT IT DOES

What UpdateAHORunCache does on Amazon Data Processing MCP Server

AI agents use UpdateAHORunCache to create or update resources in Amazon Data Processing MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Amazon Data Processing MCP Server environment.

THE RISK

Medium Risk

Why UpdateAHORunCache needs a policy

The 'Update' action suggests modifying existing cached data rather than creating new resources (Write, not Execute). Cache updates are typically reversible and don't permanently destroy data (not Destructive). No financial implications evident. High severity due to potential impact on operational data pipelines if cache is corrupted or poisoned by an agent misusing arbitrary arguments.

From the tool's definition Tool name 'UpdateAHORunCache' indicates modification of a cache related to AWS Health Operations (AHO) run data. The 'Update' verb signals reversible data modification.

POLICY

How to control UpdateAHORunCache

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 UpdateAHORunCache:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "UpdateAHORunCache": {
      "limits": [
        {
          "counter": "updateahoruncache_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

UpdateAHORunCache 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.
