Summary
Brings zero-configuration service discovery to your LLM through mDNS/Bonjour. You get six tools: list all advertised service types on your network, browse for specific services like _http._tcp or _printer._tcp, pull detailed info including host, port, and TXT records, resolve .local hostnames to IPs, and register or unregister your own services. Reach for this when you need Claude to discover printers, smart home devices, development servers, or any other network service broadcasting its presence without manual configuration. Pure Python implementation using stdio transport.
