WHAT IT DOES

What check_pihole does on Mcp Nettools

AI agents call check_pihole 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_pihole is rated Low

This tool queries the status and statistics of a Pi-hole DNS ad blocker via its admin API. It retrieves read-only data (enabled/blocking status, query counts, blocked ad counts) without creating, modifying, deleting, or executing operations. The optional API token indicates authentication for information access, not authorization for mutations or side effects.

From the tool's definition Tool description states it 'Returns enabled, blocking status, DNS queries today, and ads blocked' — all query/retrieval operations with 'api_token' described as optional. No modification, deletion, or execution of external commands.
