WHAT IT DOES

What cancel_logs_insight_query does on CloudWatch Application Signals MCP Server

AI agents invoke cancel_logs_insight_query to trigger actions in CloudWatch Application Signals MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

THE RISK

Why cancel_logs_insight_query needs a policy

The description is empty, so confidence is lowered. Based on the name, this tool cancels an in-progress query execution, which is an active operation affecting a running process. Cancellation is an external operation (Execute category) rather than a pure read or write. It is not destructive (no data deletion), not financial, and not a simple data retrieval.

From the tool's definition Tool name 'cancel_logs_insight_query' suggests it cancels a running CloudWatch Logs Insights query operation

POLICY

How to control cancel_logs_insight_query

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

policy.json

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

cancel_logs_insight_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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
