WHAT IT DOES

What check_netdata does on Mcp Nettools

It has no capability to modify, delete, or execute operations—it only fetches and displays data. The information returned is typically non-sensitive system metadata. Blast radius is minimal as the tool cannot change system state or affect security posture.

From the tool's definition Tool performs a GET request to /api/v1/info endpoint, which retrieves and returns version and operating system information without modifying any data.
