WHAT IT DOES

What check_cockpit does on Mcp Nettools

AI agents call check_cockpit to retrieve information from Mcp Nettools without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why check_cockpit is rated Low

This is a health check diagnostic that retrieves status information from a Cockpit web UI server. It reads the response code from a login page endpoint to determine if the service is healthy/accessible. This is a non-destructive read operation consistent with network diagnostics.

From the tool's definition Tool performs a GET request to /cockpit/login endpoint and interprets HTTP response codes (200, 302, or 401) to determine health status. No data modification, deletion, or code execution occurs.

check_cockpit Allowed

check_cockpit is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
