Phosphor runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 2 Sep 2026.
Hosts, metrics, Docker and authorized_keys over a macOS terminal's live SSH connections
What the code does

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.
let process = Process()
public static func writeCommand(content: String, path: String = "~/.ssh/authorized_keys") -> String {
mounts: [{src:'prod_worker_data', dst:'/data', mode:'rw'},{src:'/srv/app/config', dst:'/app/config', mode:'ro'},{src:'/var/run/docker.sock', dst:'/var/run/docker.sock', mode:'ro'}],

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.
