WHAT IT DOES

What check_matomo does on Mcp Nettools

AI agents call check_matomo 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_matomo is rated Low

This tool performs a diagnostic query against a Matomo analytics server to verify its availability and retrieve version metadata. It is a non-destructive information retrieval operation with no side effects on the target system. The blast radius is minimal—an AI agent misusing this would only perform unauthenticated reconnaissance on a known Matomo instance, which is low risk.

From the tool's definition Tool description states it 'Check[s] Matomo web analytics health via the API ping endpoint' and 'Returns version if the API responds.' The ping endpoint is a read-only health check that retrieves version information without modifying any data.
