WHAT IT DOES

What check_victoriametrics does on Mcp Nettools

AI agents call check_victoriametrics 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_victoriametrics is rated Low

This tool only reads diagnostic and status information from a VictoriaMetrics instance. GET requests with no parameters that modify state are inherently read operations. The blast radius is minimal—worst case an agent could discover that a service is running, but cannot alter data, execute code, or cause harm. Classified as Read with low severity.

From the tool's definition Tool performs health checks via GET /health and retrieves /api/v1/status/tsdb summary with no capability to modify data. Described actions are 'check' and 'retrieve' which are read-only operations.
