MCP server for mDNS (Multicast DNS) service discovery

VerifiedSTDIODesktop onlyCloud & InfrastructureDeveloper Tools

Overview

AI-generated overview

A local MCP server that lets an assistant discover, query, register and unregister mDNS services on the local network.

What you can do
List service types advertised on the local network and browse services of a given type such as HTTP or printer services, with detailed host, port and TXT record information for each service. Resolve .local hostnames to IP addresses. Register a new service on the local network or unregister a previously registered one.
When to use it
Useful when an assistant needs to find zero-configuration devices and services on a LAN, such as printers, web interfaces or other mDNS-advertising hosts, or to publish a service for others on the same network.
Requirements
A local Python environment with the mcp-mdns package installed from PyPI, run as a stdio process; the MCP client is configured with the mcp-mdns command. It operates on the local network and needs no declared credentials.
Before you install
Registering and unregistering services changes what is advertised on the local network, so those actions should be confirmed before use. Discovery exposes local network service details, including host, port and TXT records, to the assistant.

Installation

In SourceWeft

  1. Open Mcp Mdns in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Score

50% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

  • Reached in the last 30 days25 pts

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.

  • Tools listed15 pts

    Answer tools/list without a credential, or ship a package that starts in a sandbox without one.
