WHAT IT DOES

What check_homarr does on Mcp Nettools

AI agents call check_homarr 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_homarr is rated Low

This tool retrieves health/status information from a Homarr dashboard service via a simple HTTP GET request. It queries the state of an external service without modifying any data, executing code, or triggering operational changes. The blast radius is minimal—at worst, an agent could discover service availability or generate traffic, but cannot cause harm to data or systems. This clearly falls under Read category.

From the tool's definition Tool performs a GET request to /api/health endpoint to check reachability status. GET requests are read-only operations with no side effects.
