WHAT IT DOES

What enable_pihole does on Pi-hole MCP Server

AI agents use enable_pihole to create or update resources in Pi-hole MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Pi-hole MCP Server environment.

WHY IT NEEDS A POLICY

Why enable_pihole needs a policy

This tool changes the blocking state of Pi-hole from disabled to enabled. It is a reversible configuration change (the sibling tool 'disable_pihole' can undo it), making it a Write operation. Misuse could restore ad blocking unexpectedly, but it cannot delete data or cause financial harm, so severity is medium.

From the tool's definition 'Enable Pi-hole ad blocking' — toggles DNS blocking status back on, modifying the operational state of the Pi-hole service
