WHAT IT DOES

What check_komga does on Mcp Nettools

AI agents call check_komga 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_komga is rated Low

This tool retrieves health and status information from a Komga server using a standard health check endpoint. It is a read-only operation that queries system metrics without side effects. The low severity reflects minimal blast radius even if misused, as it only exposes non-sensitive health metrics and version information commonly exposed by health check endpoints.

From the tool's definition Tool performs a GET request to /actuator/health endpoint and returns server health status, version, and library count. No modification, deletion, or execution of arbitrary code is involved.
