Why UpdateAHORunGroup needs a policy

The description is completely empty, providing no information about what this tool does. The name suggests an update operation (Write category), but 'AHO' and 'RunGroup' are unclear terms in this AWS ECS context. Based on the 'Update' prefix it likely modifies something, but without further evidence I cannot confidently categorize it.

From the tool's definition Tool name is 'UpdateAHORunGroup'; description is empty and uninformative.

POLICY

How to control UpdateAHORunGroup

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 UpdateAHORunGroup:

policy.json

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

UpdateAHORunGroup 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.
