Overview

AI-generated overview

A local MCP server that gives an assistant tools to publish, subscribe, request/reply and pair over ZeroMQ sockets.

What you can do
  • Publish messages to a ZMQ PUB socket and subscribe to messages on a SUB socket
  • Send requests over a REQ socket and listen for and answer requests on a REP socket
  • Connect to or bind a ZMQ PAIR socket
  • Report ZMQ server status
When to use it
Useful when an assistant needs to exchange messages with a ZeroMQ-based system, such as publishing events, consuming a message stream, or acting as a request/reply endpoint during local development or testing.
Requirements
Runs as a local process over stdio, installed from the PyPI package mcp-zmq (pip install mcp-zmq) and started with the mcp-zmq command. A Python environment is needed, plus reachable ZMQ endpoints to connect to or bind. No authentication, environment variables or headers are declared.
Before you install
The tools open sockets, bind endpoints and send messages, so an assistant can push data into or answer on live ZMQ channels; point it only at brokers or endpoints you intend it to touch. No credentials are declared, but message contents leave the assistant toward whatever endpoints are configured.

Installation

In SourceWeft

  1. Open Mcp Zmq 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.
