disable_pihole · Pi-hole MCP Server MCP: Risk & Policy

WHAT IT DOES

What disable_pihole does on Pi-hole MCP Server

AI agents use disable_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 disable_pihole needs a policy

This tool modifies the operational state of Pi-hole by disabling DNS-level ad blocking, which affects all devices on the network. It is reversible (blocking can be re-enabled), so it falls under Write rather than Destructive. However, the blast radius is high because disabling network-wide DNS filtering exposes all connected devices to ads and potentially malicious domains until re-enabled.

From the tool's definition Disable Pi-hole ad blocking. Optionally specify duration in seconds.
