THE RISK

High Risk

Why execute_cwl_insights_batch needs a policy

The 'execute' prefix strongly indicates this tool runs queries or operations whose effects depend on the query parameters provided. Batch execution amplifies the blast radius. Without a description, confidence is reduced but not lowered below high severity, as batch query execution in CloudWatch Logs can impact logs, monitoring, and dependent systems.

From the tool's definition Tool name contains 'execute' and 'batch', indicating it runs CloudWatch Logs Insights queries in batch mode. Empty description limits certainty but the 'execute' verb combined with 'batch' processing suggests code/query execution with potential side effects.

POLICY

How to control execute_cwl_insights_batch

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "execute_cwl_insights_batch": {
      "limits": [
        {
          "counter": "execute_cwl_insights_batch_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

execute_cwl_insights_batch 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.

Create a free account and register AWS AppSync 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.
