Summary
Wraps ZeroMQ's messaging patterns into MCP tools so you can pub/sub, request/reply, and pair sockets directly from Claude. You get seven tools covering the main ZMQ socket types: publish to PUB sockets, subscribe to SUB sockets, send requests via REQ, listen and reply on REP, and connect or bind PAIR sockets for bidirectional communication. Useful when you need Claude to interact with existing ZMQ infrastructure or coordinate with distributed systems that already speak ZMQ. The package includes both the MCP server and a Python API if you want to build your own integrations. Covers the core messaging patterns without trying to expose every ZMQ knob.
