Why execute_log_insights_query needs a policy

The tool executes a query against AWS CloudWatch Logs, which is an Execute action (runs code/query whose effects depend on arguments). While the description is empty, the name and context (Lambda/AWS environment) strongly indicate dynamic query execution. Severity is high because log queries can expose sensitive data, though it's not destructive (logs are not modified) nor financial.

From the tool's definition Tool name 'execute_log_insights_query' contains 'execute', indicating it runs/triggers an operation. AWS CloudWatch Logs Insights queries can access sensitive log data and perform aggregations/analysis on logs that may contain credentials, API keys, or other…

POLICY

How to control execute_log_insights_query

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

policy.json

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

execute_log_insights_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.

Create a free account and register AWS Lambda Tool 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.

FAQ

Questions about execute_log_insights_query

What does the execute_log_insights_query tool do? +

execute_log_insights_query. It is categorised as a Execute tool in the AWS Lambda Tool MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on execute_log_insights_query? +

Register the AWS Lambda Tool MCP Server MCP server in PolicyLayer and add a rule for execute_log_insights_query: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AWS Lambda Tool MCP Server. Nothing to install.

What risk level is execute_log_insights_query? +

execute_log_insights_query is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit execute_log_insights_query? +

Yes. Add a rate_limit block to the execute_log_insights_query rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block execute_log_insights_query completely? +

Set action: deny in the PolicyLayer policy for execute_log_insights_query. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides execute_log_insights_query? +

execute_log_insights_query is provided by the AWS Lambda Tool MCP Server MCP server (awslabs.lambda-tool-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every AWS Lambda Tool MCP Server tool call.

Start from AWS Lambda Tool MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
