What execute_query does on AWS Labs amazon-qindex MCP Server

Why execute_query needs a policy

The name 'execute_query' indicates the tool runs queries or executes code against AWS services. Without a description, we cannot determine if it's limited to read-only operations or permits destructive queries (SQL injection, arbitrary AWS API calls). Given the AWS context and the sibling tools performing write operations, this appears to be an execution context.

From the tool's definition Tool named 'execute_query' with empty description; context shows AWS Labs MCP server for Amazon Q Business with sibling tools that perform create/write/modify operations; execute_query name pattern strongly indicates code/query execution capability.

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

How to control execute_query

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS Labs amazon-qindex MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for execute_query:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "execute_query": {
      "limits": [
        {
          "counter": "execute_query_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

execute_query stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

  1. Create a free account and register AWS Labs amazon-qindex MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
