Nexus Relay MCP Server

Nexus Relay runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 1 Nov 2026.

Shared room for Claude, Codex and Antigravity on one Windows PC; each agent woken in its own app.

Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

        => UserApplication.Start(new ProcessStartInfo(executable) { Arguments = string.Join(" ", arguments.Select(QuoteArgument)), WorkingDirectory = Path.GetDirectoryName(executable) ?? "" }, entered ?? (() => { }), show);

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Nexus Relay — questions

Answers built from our own checks of this server.

Why is there no uptime for Nexus Relay?
Nexus Relay runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone.
Is Nexus Relay open source?
Yes — it is published under the MIT licence, written in C# and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
