About Nexus Relay
Nexus Relay is an MCP server published by the GitHub account pironjulien. Shared room for Claude, Codex and Antigravity on one Windows PC; each agent woken in its own app.
It runs on your own machine: your AI client starts it from the PyPI package nexus-relay at version 1.8.3.
It asks for no keys or passwords.
It also needs NEXUS_RELAY_AGENT set before it starts.
Version 1.8.3 was published on 27 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
